3000 examples in mathematics. Calculations according to schemes within 100. All actions with three numbers. Answering

The manual in the form of schemes presents examples for the addition, subtraction, multiplication and division within 100. Their solution is an excellent training to form the skill of fulfilling all oral calculations provided for by the school curriculum.

The design of examples according to schemes is a good preparation for acquaintance with block diagrams and linear algorithms that are considered in the study of computer science in elementary school. Analyzing the schemes, students find the numbers with which arithmetic operations need to be performed, train in establishing causal relationships, choosing a solution method.

The material of the manual will help to consolidate the studied, to train logical thinking.

For self -testing at the end of the book, answers are given.

manual can be used in school lessons and for independent classes at home.
