Maths Even More Pizza and Things

I have created a DLO on Even more pizza and things. There is a clue of how many people are there and many more can be seated. We had to solve it and explain how we found out.

Doubling and Halving - Problem Solving

This is my DLO on Doubling and Halving. We had a list of questions we had to answer. We could only use the doubling and halving strategy to answer it. My opinion on the doubling and halving strategy is that it is useful for numbers less than 500. I would recommend a different strategy for really big numbers.
