I’ve been asking my 7th graders to work in teams of three on these Jamboards at the start of class. I created them using problems/puzzles from Don Steward’s incredible blog. I give them a new one each week and they work on them every day for about 10-15 minutes in breakout rooms with consistent groups. I’m hoping to build their fluency and also get them in the habit of puzzling their way through problems.
I will keep adding to the collection as I create them. (And okay, fine…#4 is not strictly number sense.)
#1. Balancing Mobiles
Skills: Halving, doubling, reasoning about balance and equality.
#2. Factor Trees
Skills: Factors, multiplication and division.
#3. Make the Equation True
Skills: Fluency with multiplication, addition, and subtraction. Some slides include integers.
#4. Find the Shape Puzzles
Skills: Visualization skills. Reviews squares, rectangles, parallelograms, isosceles trapezoids, and right triangles.
