About this worksheet
The chart has ten rows of ten numbers, from 1 to 100. Thirty boxes are empty, including boxes at the start and end of rows and gaps of two or three side by side.
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 6: ☐, 52, ☐, ☐, 55, ☐, 57, 58, 59, ☐
- The box before 52 is 51, one less.
- Count on from 52 to fill the next two: 53, 54.
- 56 comes between 55 and 57.
- The last box in the row is 60: ten more than the 50 above it.
Answer: 51, 52, 53, 54, 55, 56, 57, 58, 59, 60
The common mistake
What it looks like: Writing 50 at the end of the sixth row, repeating the number that ends the row above.
Why it happens: Each row ends with a ten, and the child copies the one they can see instead of counting on.
How to fix it: Count on from 59: the next number is 60. Then check the column: every number in the last column is ten more than the one above it.
