Tasks on motion without tension. Workbook. Grades 2 - 3

The technique laid down in this book is built on the fact that the student solves all the tasks for movement, practically unfolding the plot of the problem by the posectory. Having experience in solving problems according to such a technique, the child will always be able to choose the correct algorithm for solving problems and will never confuse the action of multiplication and division when solving the problem (the most characteristic mistake!).
In addition, constant emphasizing the relationship of tasks for movement and tasks about work, as well as solving problems with economic content allows you to learn how to represent the essence of these families of tasks. If the student copes with the solution of all> tasks from this manual, it means that 90% of possible difficulties in the fourth grade simply do not arise.
