Today I uploaded a quick math product. I added domino addition sheets. When children use dominoes to learn addition they see the visual of the dots as well as the number fact that they write themselves. I always used this when I was teaching kindergarten. Blake has had domino sheets in pre-K but they had the dots filled in and the kids didn't use actual dominoes. I think they have more fun with the real thing... and they learn more by filling in all the information themselves. my page on Teachers Pay Teachers... it's free there too! My next product will have a few free pieces, but the rest will be sold.
