I found these great 3 section trays at the Dollar Tree and they are perfect for sorting. I use them for all types of things, but this one is sorting coins. To make it I used clear packing tape to adhere a coin to each section.
The kids do great sorting these and after they sort we count the number of coins(we are not ready to to count the actual amount of money yet). I will have more ideas for this in the next few days. I jut forgot to take a picture and pictures are always better!
