BYOM Lesson Workbooks
# BYOM 4th Grade Workbook

The
proposed Russian Math Books for primary school mathematics course is part of a unified continuous
mathematics course for preschoolers, primary school, and grades 4-5 of
secondary school. It is designed to achieve new educational objectives,
including personal, cross-curricular, and subject-specific learning outcomes,
as well as readiness for self-development based on fostering students'
cognitive motivation, universal learning actions, and overall learning skills.

Mathematical knowledge in the course is not considered an end in itself but rather a means of developing specific personal and cross-curricular educational outcomes, mathematical activities, and the development of children's thinking, senses, emotions, creative abilities, and motivational factors. The stated objective is achieved through the use of the didactic system of the activity-based method by

L. Peterson. The technology of the activity-based method involves the following structure for introducing new knowledge in lessons:

1. Motivation (self-determination) for the activity.2. Activation of prior knowledge and identification of difficulties in a trial learning action.3. Identification of the place and cause of the difficulty.4. Construction of a project to overcome the difficulty.5. Implementation of the constructed project.6. Initial consolidation with verbalization in external speech.7. Independent work with self-assessment against a benchmark.8. Integration into the knowledge system and review.9. Reflection on the activity (lesson summary).Lessons of other types follow a similar structure: reflection (i.e., review and consolidation of knowledge, self-assessment, and correction of errors), as well as lessons focused on building knowledge systems and developmental assessment. Such lesson construction not only helps students develop a solid foundation of mathematical knowledge but also engages them in performing a comprehensive set of universal learning actions during each lesson.

The complex of pedagogical conditions that ensure the implementation of the activity-based method technology includes the following didactic principles: activity, continuity, holistic representation of the world, minimax, psychological comfort, variability, and creativity. These principles maintain their significance in the system of educational and management support for children's well-being. Thus,

L. Peterson's educational system enables the establishment of a unified educational, developmental, and health-preserving process based on an activity-based approach.

The educational system can be implemented at different levels: the basic level,
the technological level, and the system-technological level. The basic level of
the activity-based method (ABM) includes the following 7 steps:

When working at the basic level of ABM within the framework of didactic principles, the principle of activity is transformed into the principle of activity activation within the traditional education system. Special attention should be paid to the principles of minimax and psychological comfort, as their proper application allows each student to progress at their own pace, tackling challenges at their "maximum" but manageable level of difficulty. Ignoring these principles, on the other hand, can lead to student overload.

The described lesson structure systematizes the innovative experience of Russian schools, making it an accessible step for every teacher. It yields rapid results, including positive dynamics in students' knowledge acquisition, and development of their thinking, speech, and cognitive interest. The basic level of ABM can be easily mastered by any teacher during their initial acquaintance with the educational system by

L. Peterson, and it serves as a starting point for self-development when fully adopting the activity-based method.

The technological level of ABM implementation refers to the level of teacher's
work where the transitional structure (8 steps) and the system of didactic
principles of Peterson’s educational system are implemented. Concepts such as
benchmark, self-assessment benchmark, and detailed model are included in the
practice, and motivation for cognitive activities is organized at the levels of
"I want" and "I can".

The technological level of ABM implementation allows for the following:

1. Ensure all the outcomes of the basic level of ABM implementation.2. Create conditions for the development of general learning skills, including the ability to learn.The system-technological level of ABM implementation refers to the level of teacher's work where the comprehensive structure of educational activities (9 steps) and the system of didactic principles of Peterson's educational system are implemented. Concepts such as educational activities and their structure are included in the practice.

The system-technological level of ABM implementation allows for the following:

1. Ensure all the outcomes of the basic level of ABM implementation.2. Develop general learning skills specified in the educational standards.

Connection with practice, real-world problems

Full-fledged mathematics education is impossible without children understanding the origin and significance of mathematical concepts and the role of mathematics in the system of sciences. Therefore, one of the main tasks of the school curriculum is to reveal to students all three stages of mathematical knowledge formation.

These stages are:

1. The stage of mathematization involves constructing a mathematical model of a fragment of the real world.2. The stage of studying the mathematical model involves constructing a mathematical theory that describes the properties of the constructed model.3. The stage of applying the obtained results to the real world.For example, natural numbers are not initial abstractions, so their study is preceded by familiarizing students with finite collections of objects. Similarly, the study of addition and subtraction of natural numbers begins with the consideration of concrete operations of combining finite collections and removing a part of a collection. The study of formal operations of addition and subtraction of two-digit numbers is based on operations with symbolized representations of these numbers using dots and shapes (following the historical development of these operations).

The above-mentioned demonstrates how the first stage of mathematical modeling, the construction of mathematical models of the surrounding world, is reflected in the mathematics curriculum for first grade. The second stage, intra-model investigation, is associated with the study of addition and subtraction operations with single-digit numbers, constructing an addition table, and studying operations with two-digit numbers. Finally, the third stage is reflected in solving word problems where the learned operations with numbers are applied in practical contexts.

The curriculum achieves continuity between preschool education, primary school, and secondary school through the integration of technology, content, and methodologies, ensuring a seamless educational process across all stages of learning. The selection of content and the sequence of studying key mathematical concepts were based on a systemic approach.

The development of the thinking style necessary for the successful use of ICT (Information and Communication Technology) leads to a reassessment of the importance of many skills and abilities. For example, the ability to create and implement an action plan, strict adherence to given rules and algorithms, assess the plausibility of the obtained answer, explore various solution options, organize information search required to solve a given problem, and more, gain particular significance. Therefore, Peterson’s mathematics course effectively addresses all the objectives of the subject area "Mathematics and IT.«

The course has a differentiated approach, allowing children of different levels of preparation in schools and classes of all types to work with it based on the principles of minimax and psychological comfort. The selection of children to work with the course is not assumed based on their level of preparation, but rather on the teacher's level of preparation.

The instruction is conducted at a high level of difficulty (the "maximum" level), meaning it is within the "zone of proximal development" of the most advanced children. It takes into account each child's individual characteristics and abilities and fosters each child's belief in themselves and their abilities.

Practically, this means that BYOM presents tasks and the pace of learning that are of a sufficiently high level. From the very beginning, all children are placed in situations that require intellectual effort and productive actions. However, in instructional tasks and independent work, only the child's success and progress relative to themselves are evaluated. Mistakes are seen as working situation that requires correction, identification of the cause, and rectification. Ongoing and final assessments are conducted at a lower level than classroom work, which practically leads to the disappearance of low grades. Final grades are based on the number of "achievements" (which are evaluated with high grades only) and marks for tests. Low scores may appear very rarely, only when a child has shown negligence or failed to complete an assigned task that is clearly within their capabilities. It is preferable if the child themselves gives them a negative grade in accordance with the norms established in the class.

However, the high level of material presentation is not considered as a mandatory requirement, but rather as a suggestion and an opportunity for each child to achieve success, motivating them to take action. Therefore, the teacher should notice and support any, even the smallest, success of the child - their activity, involvement in the process of finding a solution, their accurate judgment, or simply an attempt to propose their own hypothesis. A student's incorrect answer should not evoke a negative reaction from the teacher, annoyance, or lecture. It is better if one of the students corrects the answer, saying, "What do you guys think?" In this situation, it is the teacher's role to provide moral support to the one who made the mistake: "Well done! You helped us understand!" or "Do you agree? Do you understand now? Well done!" and so on.

The principle of minimax is a self-regulating mechanism for multi-level learning. As mentioned above, it does not require any special selection of children to work with it. Furthermore, engagement in educational activities, internal activity, and the development of a habit of reflecting on each step is particularly important for children with developmental issues. However, working at a high level of difficulty must be accompanied by creating an atmosphere of trust, respect, and friendliness in the classroom, allowing each student to believe in their abilities and truly "unfold themselves." The teacher must believe in the student, saying, "You can do it!" The students must believe in themselves, thinking, "I can do it!" and all the other students in the class should believe in their classmates, saying, "They can do it!" Otherwise, education will lose its personal significance for the child, and the school will not be able to fulfill its main mission - to help the child achieve their individual maximum.

The volume of tasks in the course sets the level of the individual educational trajectory for the most prepared children. Therefore, it is not expected that every child will complete all the tasks. Only 3-4 key tasks on each new topic and review tasks are mandatory for everyone, which reinforces the essential learning outcomes. The range of tasks can be expanded for more advanced children. However, overloading children, including with homework, should be avoided.

The consolidation and reinforcement of knowledge in the main content and methodological lines of the course (numerical line, text-based problem-solving) are conducted in parallel with the exploration of new mathematical ideas in additional lines (geometry, algebra, data analysis, etc.). Therefore, the practice exercises do not tire the children, especially since they are usually presented in a playful form (code cracking, riddles, etc.). Each child with a lower level of preparation has the opportunity to gradually master the necessary skills from the essential learning outcomes, while more advanced children are constantly provided with intellectual stimulation, making mathematics lessons appealing to all children, both strong and less prepared.

It is fundamentally important for each child to experience the joy of discovery and develop confidence in their abilities and curiosity in every lesson. Interest and success in learning are the key parameters that determine the comprehensive moral, intellectual, and physiological development of a child and, therefore, the quality of working with children.

Some of the topics included in the 4th-grade curriculum have traditionally been taught in the 5th grade. The decision to introduce them at an earlier stage is driven by several reasons. One of the most significant reasons is the need to take into account sensitive periods, which are the most favorable periods from a psychological perspective for acquiring certain knowledge. For example, in the 3rd grade, learning about multi-digit numbers within the range of 12 digits is easier than in the 5th grade, because children enjoy working with "long" numbers.

By the 4th grade, students accumulate fatigue from complex calculations, and they are not only logically but also emotionally ready for the next step - the introduction of fractions. The new numbers, their properties, and the algorithms that students construct on a tangible basis evoke surprise, joy, and sometimes even enthusiasm from their independent victories (which teachers in higher grades do not often observe when teaching fractions in the 5th or 6th grades). Through this emotional reinforcement, necessary training in operations with whole numbers is conducted simultaneously with the study of fractions, and the corresponding techniques for mental and written calculations are brought to the level of automated skill.

The transfer of this material from the 5th grade to the early years of the school became possible thanks to the new methods proposed in the curriculum, such as graphical modeling of text-based problems, associative techniques for solving equations, and others, which significantly reduced the time required for studying many topics in the curriculum.

In the 4th grade, there are several successful methodological innovations. Among them, we can mention the technique for solving fraction (percentage) problems, problems involving simultaneous motion, solving inequalities with natural numbers, exploring the properties of geometric shapes through constructions and measurements, reading and constructing motion graphs, and more. For example, the timely introduction of the percentage symbol (%) in the 4th grade as one of the notations for a hundredth part of a quantity helps eliminate the difficulties that students in higher grades face when studying percentages. It also improves the quality of solving simple fraction and percentage problems (for cases involving operations with numbers) in the future.

Thanks to the described transfer of material from higher grades to the early years of school, time is freed up in the 5th and 6th grades to address topics that are significant for 11-12-year-old children from both psychological and preparatory perspectives for their further study of the mathematics curriculum in grades 7-9. These topics include logic, modeling, the development of geometric concepts, variational and functional thinking, and more. Moreover, the quality of learning the middle school mathematics curriculum is significantly enhanced because the methodologies presented in the primary school course eliminate the need to translate the conclusions into the language used in higher grades.

Creative assignments in the textbook's work system

A highly effective means of allowing each child in the class to unfold and realize their potential is through creative work. Creative assignments, where children come up with ideas, create, and invent, should be regularly introduced, preferably 2-3 times a week. In these assignments, children can come up with examples for a learned computational technique, create a problem based on a given expression (e.g., 60 + 15 × 3 or a ÷ 5 − b ÷ 8), solve a problem of a specific type (e.g., related to motion, cost, work) or based on a given theme (e.g., about sports, animals, historical events), draw patterns or geometric shapes with specified properties (e.g., a right triangle, a pattern of circles), decode or encode the name of a city, book, or movie using computational examples, and so on.

Creative assignments are typically given as additional homework alongside the mandatory portion and are never graded poorly. The most successful creative works can be compiled into a "Problem Book" at the end of the year, with the students themselves being the authors of their respective works. Such assignments, where children act not as mere performers but as creators, have a profoundly positive impact on the development of children's personalities and contribute to a deeper and more solid assimilation of knowledge.

Volume and difficulty level of homework

It is recommended that students be given two-level homework assignments, consisting of a mandatory part and an optional (additional) part.

The mandatory part should be manageable for the child to complete independently and should not exceed 15-20 minutes of their independent work time. It is also recommended to give assignments based on the children's own choice, for example: "Choose and complete one task from #4-7 that you like."

The optional part, which is completed at the student's discretion, can include additional tasks, asterisk-marked assignments, and so on.

Types and forms of classroom work

It is necessary to diversify the types and forms of work in the classroom. The lesson should include collective, group, and individual forms of work, as well as oral work and work in grid notebooks. The practice of computational skills should be systematic and sufficiently intensive during lessons, but should not exceed 3-4 minutes. It is advisable to give computational exercises a developmental character by selecting answer numbers in such a way that the resulting series can be analyzed and classified, and patterns can be identified by the children. This will help not only to reinforce counting skills but also to prepare children’s thinking for activity-based methods.

When forming concepts using the methods adopted in the course, all types of memory are engaged in students – not only visual and auditory memory but also motor, imagery, tactile, and others.

Working in the workbook should not exceed, as a rule, 10-12 minutes. It mainly involves the independent completion of tasks by the students, which have been prepared beforehand during frontal work with similar but different tasks.

The time for independent task completion is usually limited (typically, from one to three to four minutes). Then, the task is checked using a Smartboard. Children compare their solution with the model answer or sample for self-checking and mark themselves with a "+" or "-." As a result, the child's ability for self-monitoring is purposefully developed.

Since the tasks are checked by the children themselves when completed independently, the teacher focuses primarily on the children's developed self-monitoring skills and record-keeping accuracy during their assessment.

The
system of knowledge assessment

The course includes a multi-level system of knowledge assessment: self-monitoring when introducing new material, peer monitoring during its practice, instructional control through independent assignments, ongoing assessment through periodic tests during the academic year, and a final assessment comprising two stages: a transfer test ("minimum") and a final test (to assess the level of program mastery).

The independent assignments are set at a high level of difficulty, and therefore only success is evaluated. Specifically, if the entire independent task is completed without errors (typically achieved by 3-5 children in the class), a grade of A is awarded. After each independent task, children who made mistakes work on correcting them.

If the error correction is successful and the teacher observes that the child has understood the material, a grade of B or even A can be given for that task. Grades of F or D are not given for independent assignments. "No grade" (indicating that nothing was earned) serves as a more significant signal for the child to be active and correct their own actions than receiving poor grades. The teacher's task is to motivate each child to understand their mistakes and correct them.

The level of tests should be lower than that of independent assignments (but higher than administrative control), and all children should be evaluated. It is recommended that test tasks be designed so that approximately three-quarters of the class can handle them and achieve grades of A or B.

Intensive exercises to practice computational skills should be included in almost every lesson. It is advisable to give these exercises a developmental character by selecting answer numbers that allow children to analyze, classify, and identify patterns in the resulting series. This approach will help not only consolidate counting skills but also prepare children for active problem-solving methods.
