15,000 Examples in Mathematics. Non-Table Multiplication and Division. Grades 3-4

The resource presents all methods of calculations and all types of tasks for automated calculation skills in non-table multiplication and division: all calculation algorithms (detailed explanation of how the operation is performed); tasks that allow for deeper understanding of the... material: find errors in examples, write the correct variant; insert the missing number or operation sign; insert missing numbers to make the equations true; solve equations; solve chains of examples; fill in the empty cells of schemes (calculations according to schemes).
Verification works will help check how well the topic is learned. By completing tasks, the student practices establishing cause-and-effect relationships, choosing a method of solution, develops mathematical intuition and logic, and practices calculation skills to the point of automatism.
