Note:
This was quite hard and did not really give the bottom kids access to the problem. I think is was the combination of doing 5ths, which he had not used before in this unit, having and numerator of 2, and the added in measurement (which had a lot of kids stuck on - which side are cm and me running around making sure people where measuring from 0).

You have a long strip of gum. It was [15cm, 25cm, 1m] long. My dog took a bite before I could stop him and ate 2/5 of the strip. How much was left?
Here is a hook so the kids knew what I was talking about...
How hard this guy finds it to open is a horribly painful anticipation....
