Training apparatus. 4th grade. 100 tasks in mathematics with solutions and answers. Rydze O.A.

This manual is intended for students of educational organizations. It is aimed at teaching fourth graders the ability to analyze the text of the problem, represent the problem in a convenient way to solve and build a solution using a model; Find different solutions, control the course and answer of the problem. Each section provides for a solution on the model and independently different types of tasks traditionally studied in the fourth grade: on the use of arithmetic operations (addition, subtraction, multiplication, division); calculation of the share; comparison and change of values ​​(increase/decrease by several units, several times); finding logical connections, dependencies between the values ​​in plot situations. For the development of control skills and self -control, a fourth grader is offered tasks of the section “Decide on our own”.
