The hundreds chart is the workhorse of early math: it teaches counting sequence, patterns in tens and ones, and the +1/-1/+10/-10 moves that make mental arithmetic click. This one comes with seeded gaps for the child to fill.
Choose easy, medium, or hard to blank 10, 20, or 35 numbers, or drop to the 1-50 chart for kindergarten. Every shuffle deals a completely fresh set of gaps, and the answer key prints the missing numbers in green.
