Dear parents!
All of you have heard of the multiplication table, but not all of you know about the table of addition and subtraction within 20 - an oral account. Knowledge of the table - the basis of the account, especially in cases where the sum of the numbers is greater than 10. These cases arouse the child's difficulties. We are ready to help you. Training exercises will help your students in successful learning of mathematics. We offer them for your first-graders.
