We have had so many acorns in and around the school grounds that they just couldn't be ignored. They became the ideal resource for maths.
First, we had to estimate how many acorns were collected by Walter.

Then we had to count them all. The students agreed that counting in tens would be a good way to get through the pile so every child took 10 acorns at a time.
Lastly, we had to count the groups of ten...290, 300, 310, 320!
