Question: Fill in the missing digits in the multiplication.
Predict: I thought this problem would be about multiplication.
Clarify: I had nothing to clarify.
Find the big picture: What are the missing numbers?
First I worked out that 3×6 is 18 so I put the 8 down and carried the 1.
Then I worked out that 3x? had to be 12 because plus the 1 would be 13, and that was 3×4, so I put down the 4 and carried the 1,
Finally I worked out that 3×2 is 6, plus the 1 is 7, so I put the 7 in the last box.
Summary: I used the guess, check and improve method.
