Will's adding game

Will is ready for adding and subtracting. This summer Mike gave Will an adding worksheet and I was very surprised that he could do the entire worksheet with very minimal help. We just gave him candy to use with his worksheet and it helped him understand the concept so well. I was trying to think of something else that would help him add but wasn't just a worksheet. I found this idea (again, don't know where) and will use this with Will. I looked for dried beans but couldn't find where we had them hidden so we just used Good and Plenty.
