Five Steps to Five. A Trainer for Oral Calculation within 100 with Transition through the Decade. Addition

"Five Steps to Five" is a new type of trainer aimed at training students in mastering the addition-subtraction table of numbers. This workbook features examples with transitions through the decade.
To facilitate the training process, we have separated the actions: subtraction... is provided separately, and addition separately.
To avoid tiring the child with monotonous calculations, we have inserted game pages after pairs of similar pages.
This workbook includes the possibility to assess the correctness of the calculation: color the clown's face.
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 pre-teared out and used at the knowledge assessment stage after completing the entire workbook.
"Five Steps to Five" is addressed to a wide range of students from different schools working based on various educational materials.
