This worksheet contains six addition grids of increasing difficulty. The first has low single digit numbers whereas the final has higher double digit numbers, no larger than 20.

Each A4 page contains two challenge grids so you can save on paper whilst still having enough space for those children who write large than others.

Depending on your children鈥檚 ability, you can set the timer anywhere from a minute to five if necessary. It鈥檚 good way to assess their ability to perform arithmetic quickly and also makes for good homework practice.

My children generally really enjoy the challenge!
