This 'addition with numbers' puzzle is a great enhancement tool for helping with addition. This puzzle can be used as both a jigsaw puzzle and a memo game which adds that extra element of entertainment and challenge. Featured in this puzzle, are 8 rows in sets of two, where the puzzle pieces on the top row show the basic addition, and the piece directly underneath, displays the answer.
One puzzle piece has a problem while the other piece shows the solution. The numbered 'solution' puzzle piece is coloured which encourages and engages attention. Using this puzzle will quickly help you to familiarise yourself with the answers, helping you to learn fast, in a fun and exciting way.
The answers are displayed in chronological order from 1-20, and this helps the younger children to count easily. Imprinted on the frame, you will find an additional basic 'problem' which equals the answer directly above it. Because of this, the memo game can be played without any puzzle pieces in the frame.
