This worksheet is a 1–100 hundreds chart with about 40% of the squares blank. To fill them in, kids use the chart's structure: the number to the right is one more, the number below is ten more. That makes it a place value exercise as much as a counting one. A child who sees 47 above an empty square can reason that it must be 57.
Click New problems for a new set of blanks, and raise Missing numbers as your child gets more confident. At 80–90% it's nearly a blank chart. The answer key shows the missing numbers in red.
Tips for using it
- Have your child explain one answer using 'one more' or 'ten more.'
- Start at 20% missing for kindergartners, 40–60% for 1st graders.
