Five Steps to Five. A Trainer for Mental Arithmetic within 20 with Carrying Over through the Tens. Addition

“Five Steps to Five” is a new type of trainer aimed at helping students master the addition-subtraction table of numbers. This workbook presents examples with carrying over through the tens. To facilitate the training process, we have divided the actions: subtraction is given separately, and addition separately. To avoid tiring the child with monotony, we have inserted game pages after pairs of identical pages. This workbook also includes the ability to assess the correctness of the calculation: coloring the face of a clown. The last, fifth task on the page is focused on speed, so it can be used with a stopwatch. The central control pages can be torn out beforehand and used during the knowledge assessment stage after completing the entire workbook. “Five Steps to Five” is intended for a wide range of students from different schools working with various educational materials.
