'Arrange the shapes in order of size. Put the smallest first.'
The first thing to do was look at the mathematical language and check we understood what it meant. An important question we asked was;
'What is size?'
We discussed comparing them by sight or cutting them out to compare. This was not very mathematical so we came up with the idea of measuring the longest side or working out the perimeter. Once we had these measurements then we could put them in order. We needed to measure and add correctly. Our answers were different depending on the strategy we chose.
