3000 examples in mathematics. Tests and verification works. 1st grade

This manual contains tests and verification works on one of the basic topics for 1st grade - «Addition and subtraction within 10». Many parents are convinced that their children calculate very well, but one can only be completely confident in this if the counting skill has been brought to automaticity. In this case, the answer to an example is written by the child within 3-5 seconds. Each page provides examples for independent solving. After them, on the right, the student writes down the time taken to solve them. On the left, there are digits indicating the ideal time, satisfactory, and poor results that should make the student think. Along with each test, there are examples for working on errors. The manual can be used as additional material in mathematics lessons, as well as for home study.
