- addition and subtraction
- use the hundred chart as a number line to do addition and subtraction; show how to add or subtract the tens first by counting up or down, then the ones by counting left or right.
- or use dice and add/subtract all the way to 100/1.
- multiplication and factors
count by a number from 2 to 10 and discover the pattern it makes. use colored disks or print multiple hundred boards: one set is a complete hundred board and the second set is the number by which you are counting, colored to match the bead stair.
- odds and evens
after discussing the concept of odd and even, cover 10 odd or even numbers from a set of 20 numbers and discuss patterns or observations
- cut a hundred board along the lines into various puzzle pieces for the child to put back together
