I love using incentive charts in my resource room. That being said, not every child is the same. Some children need a reward sooner than others. These charts are the same design, but the charts have different number of squares to fill. I have created the same chart with 20, 16, 12, 10, 8, 6 or 4 squares. There are 4 designs with every size chart. You choose what you need for each child. Since these all have the same design, they also work great as one wants to increase the behavior and decrease the reward.
At four per page, these reward charts are perfect size for any chart stickers. Why buy charts, when you can print these cute charts and have exactly the size you need?
