I still had a lot of foam sticker letters left over from another project, and the other day I found a new use for them. I labeled several disposable cups with common letters, separated those particular letters from the rest of the foam alphabet and let M sort them.
For some reason, sorting is still more of a challenge for M than simple, one-to-one matching; so this activity took a little work for M to catch on. In the end, though, it seemed worthwhile.
