Looking for free games and activities for your Promethean or SmartBoard? Stop by Topmarks Education. The site offers resources for teachers and parents. It is based in the United Kingdom, so grade level designations are different from the United States (Key Stages instead of grade levels). However, it is easy to figure out which resources are best for your grade level based on the topics. There are activities for math, literacy, geography, art, music, and science.
There are a few activities that I plan to use with my Basic Skills kids, especially the Place the Penguins place value game. It is definitely worth stopping by this website.
