Maths Mate Term Four Sheet Six Question #24

Predict: I predict this problem will involve multiplication, numbers and missing numbers.

Read: “Fill in the missing digits in the multiplication.”

Clarify: nothing to clarify

What’s the BIG Question?: What digits go in the boxes that also fit into the multiplication sum?

Strategies: “Have I seen a similar problem” (For more strategies, check out my “Mathematician’s Toolbox” page, here is the link: Enjoy!)

Solving Procedure: Firstly I did the sum of 6 x 3 which equalled 18 so I put the 8 in the available box and carried the 1. Next I knew that I had a carried 1 and the bottom number in the answer section had to be a 3 so I put 4 in the next available box and did the sum 3 x 4 + 1 I got 13, so I then carried the 1. Finally I did the last sum of 3 x 2 + 1 and got seven so I put 7 in the last available box.

Summary: In the end I completed the multiplication sum and used my estimated strategy. My predictions were also correct!
