About this worksheet
The chart has ten rows of ten numbers, from 1 at the top left to 100 at the bottom right. Ten boxes are empty, scattered across the chart, and the child writes the missing number in each.
A 100 chart shows the patterns in our numbers: across a row the ones go up by one, and down a column every number is ten more. Filling the gaps means using those patterns, which builds the number sense children use for adding and subtracting tens.
A worked example
Row 2: 11, 12, 13, 14, 15, 16, ☐, 18, 19, 20
- Look at the number before the gap: 16.
- Count on one: 17.
- Check with the number after: 17 comes just before 18.
- Write 17 in the box.
Answer: 17
The common mistake
What it looks like: Filling a box at the start or end of a row with the wrong ten, like writing 51 where 60 belongs.
Why it happens: At the edges of the chart the neighbor in the row is missing or on another line, so the child guesses.
How to fix it: Use the column: every number in a column ends in the same digit and is ten more than the one above. The box under 50 is 60.
