Grade 2 learning - green screens and advanced rekenreks

Bonjour! This week the students continued refining and revising their instructional video for a game using the rekenreks. They are mostly ready to share with the other students next week. Next we looked at constructing some more advanced rekenreks using smaller beads - this time that go up to 100 - students can modify their game to play with numbers to 100 and use their more advanced tools for higher-order mathematics. Here is a partially - completed large number rekenrek:

The next five rows will be different in some way so as to show quickly if a number is more or less than 50. Bon weekend!
