**Predict:** I predict that this problem will be about weight and quantities of things.

**Read:** Which deal costs less per gram?

A] $5 for 500 grams

B] $3 for 250 grams

**Clarify: **I have nothing to clarify.

**Strategies/Mathematicians Toolbox: **‘Prior knowledge’, ‘Work it out backwards’, ‘Try a simpler problem’.

**What’s the BIG question? **Which costs less: A or B.

**Working out: **Firstly I went well if it costs $5 for 500 grams then for every $1 you get 100 grams. With B I knew that A was cheaper because for every dollar in B you get less than 100 grams for $1 but in A you get 100 grams for $1.

**Summary:** The answer I got was A. I used strategies to help me work it out and with the prediction I did have to use some things to do with weight and quantities but also comparing numbers and weights together.
