Make a peek-a-boo cross that shows kids the relationship between a number and the other numbers touching it.
Students choose one of the 100's charts and a recording sheet. Toss a game chip onto the board and place their recording sheet over their number. They will see their number through the small hole in the center box and then complete the remaining four boxes for 10 less, 1 less, 1 more, 10 more. I put the sheets in a clear plastic sleeve so they are reusable. Students check their answer by referring back to the 100's board.
