Hundred Square

This activity provides an opportunity for students to work on spatial visualization and number sense together. Learners are presented with a hundred grid and told there is another printed on the reverse side. They must work out the unseen numbers for several positions on the grid. Ideas for implementation, extension and support are included along with a printable sheet of grids.

    • What better way to have students get on familiar terms with the hundred grid than to have them visualize it in reverse, or upside down, or in jigsaw puzzle-like sections? For similar resources see Number Grid, Jigsaws and Give the Dog a Bone, all in this catalog.
