The learning connection
Embodied cognition is at play as students physically arrange cards representing steps in a proof. By manipulating visual elements, they bridge abstract ideas with tangible actions, reinforcing their grasp of deductive reasoning.
Try it with your learner
1. Create 10 index cards with different steps of a proof (e.g., statements, reasons). 2. Shuffle the cards and mix them up. 3. Set a timer for 15 minutes. 4. Work together to arrange the cards in the correct order to form a valid proof. 5. Discuss why each step is necessary. 6. Try creating your own proof with new cards — can you simplify it?
