Mathematics. 1st Grade. Developing Subtraction and Addition Skills

This textbook will facilitate effective learning of mathematics in the 1st grade. In a simple and accessible form, it will allow for the development, consolidation, and assessment of the child's key skills on the most important topics of the subject studied.

Carefully selected examples will help not only to master the simplest arithmetic operations of addition and subtraction within 20 but also to learn how to correctly present mathematical solutions.

All tasks are clearly formulated and systematized within a single spread. The work completed on each page can be independently assessed by the child - by circling a sun in the margins with the corresponding grade.
