Nine rows, one for each step from 2 up to 10, with a labelled tab at the left of each and three numbers missing from every sequence. The blanks are placed at different points along each row rather than always at the end, so a child cannot simply keep adding from where the numbers stop. Twenty-seven numbers to fill in total, running as far as 100.
Every row here is a times table written out in full, which is the reason this page belongs with the multiplication ones rather than off on its own. A child who can count by 7s to 70 already knows the 7 times table and often has not noticed. Pointing that out once, while the finished page is still in front of them, tends to do more for confidence than another sheet of facts would.
