Why did Reception only have one shoe on today?

If you’d popped into Reception class today you would have found them all sitting on the carpet with one shoe on. Why?

They were having a maths lesson and were practising their estimating skills. They filled their shoes with Unifix bricks and had fun trying to estimate how many they managed to fit in. First they had to make a guess and wrote the number down on a white board then they counted in tens how many actually fitted in their shoes. There were lots of great guesses – large and small – all round!
