Arrange these shapes in order of size. Put the smallest first.
How are you deciding on the order?
"I printed the shapes and then measured the length of each shape at the longest point."
Louise and Rosie said:
"We observed the area of each and tried to rearrange the shapes in our heads to compare them."
"I cut out the shapes then cut each up into little pieces and laid them on top of each other to see which was bigger. I also put them on a grid with small squares and counted the number of squares for each."
