Make the thinking visible
Example to work through together
4 × 3 = 12 because four equal groups each contain three marbles.
Try the starter activity
Draw 4 bags with 3 marbles in each; write 4 × 3.
Student practice
Draw 5 bags with 2 marbles each. Label factors and product.
Quick check for understanding
How many marbles?
Sample answer and teacher guidance
Sample answer: 12
Listen or look for: 5 × 2 = 10; five groups of two total ten.
Invite the learner to explain, demonstrate, draw or dictate their reasoning. Revisit a teaching step when the explanation is unclear.
Make it work for your learner
A little more support
Use physical cups and counters and count groups separately from items.
An additional challenge
Write a different equal-group story whose total is 12.
