Mathematics. Grade 2. Account within 100. Part 1

This manual contains 3000 examples for addition and subtraction within a hundred. The theme "Hundred" is one of the basic topics of the elementary school. Like any other topic studied by a child at this age, it requires attentive understanding and good consolidation.
Many parents of seven and eight-year-old schoolchildren are convinced that their children think very well, but you can completely be confident in this only when the account skill is brought to automatism. In this case, for example, the student writes an answer after 4-7 seconds.
How to use the book
Each page shows 6-7 columns of 52 example. At the end of the column, time is recorded. In the lower left corner, control numbers are indicated: the ideal time of solving one column, satisfactory and the result that should make the student think of. No need to demand from the schoolboy at this time the calligraphic writing answers.
It is difficult for the teacher to check such a large number of examples, so it is better if the time spent on the solution of each column will be celebrated by adults.
In order to achieve good results, every day you need to solve one page.
The manual can be used as additional material in mathematics lessons, as well as to work at home
