Francois Tregouet, STEAM Coordinator and 3rd grade teacher, lead an collaborative project between 4th graders and kindergarteners. The 4th graders studied polygons and learned how to code Probot to trace them. Kindergarteners learned to identify polygons, named them, both in English and French, and recognized their names in capital letter, lowercase and cursive. Both grades then met: the 4th graders coded Probot to trace polygons and Kindergarteners had to name them orally, and identify them by their writing as well. This is a perfect example of peer teaching, with a twist of high-tech!
