Predict: I predict this problem is going to be about numbers, division, multiplication and problem solving.

Read: “I Think of a number, multiply it by 3 and then divide by 2. If the result is 18, what was the original number?”

Clarify: *nothing to clarify *

What’s the **BIG** Question?: What was the original number that was thought of in the question

Strategies: “Guess, Check and Improve” (Please follow this link to more strategies at my mathematicians-toolbox)*:http://kaitlin2012.global2.vic.edu.au/maths-toolbox/*

Solving Procedure: First, I did a lot of guess check and improving. When I got the answer 36, I then decided that 36 can be divided by 2 to get 18. So then I thought of a number that timed by 3 equalled 36 and that was 12. To finish off with, I made an equation like this: 12×3 divided by 2 = 18 so that my answer could be 12.

Summary: After all i got the answer 12. I used my strategie guess, check and improve. I was very happy to get my strategie I chose right!
