Points Of Interest

Purpose

• To give the child more practice with number combinations, and help him to memorize the addition tables.

Variation

The child takes each slip from the box, finds the answer and then puts the slip in the lid of the box so that he does not repeat it. He can record the answer or just memorize it. The answer may be checked on the summary of the addition tables or an answer provided on the back of each slip.
