Differentiation in Action

Make Connection s: Students need to spend time using base ten blocks to understand addition. Be sure that connections are made as students as students move to drawing representations and then to abstract. Have base-ten blocks on the desks throughout the entire topic for student use. GFletchy 3-Act Math Task: It All Adds Up. This task pairs nicely with Open Middle: Sums to 100. Students can also be challenged to model their solutions with pictorial representations or base-ten blocks.
