This is an interactive hundreds chart. Students can choose a color and splat numbers from 1-100. Use it to practice one more, one less, ten more, and ten less. It is also helpful when counting by ones, twos, fives, and tens.
There are four numbers that are missing from the hundreds chart. A cute little character is peeking out of the square of one of the missing numbers. The student needs to drag the correct missing number back to the square.
