On Thursday, Mrs Davey and Mrs Purchase decided that we could eat doughnuts in maths but only if we could complete the maths challenge that they set us.
Can you cut a doughnut into 8 equal parts using only three cuts? AND…. You can’t eat it or lick your fingers!
We tried to fold paper circles first and we were successful but you can’t fold a doughnut. Three folds were easy but we had to use a lot of our problem solving skills and determination to work out three slices. In Maple class, Daniel was first to realise that if you cut the doughnut twice and then made a tower for your third cut you would get eight equal pieces. Meanwhile, in Apple class, Eddie realised that if you turn the doughnut on its side and slice through then lay it back down to cut into halves and then quarters you would also get eight equal chunks. Others quickly followed suit and soon nearly everybody had eight pieces.
The teasing teachers then asked us to eat 3/8 of our doughnuts and to work out how much we had left. It was so delicious and so tempting that Harry had already eaten 8/8!
Who knew that fractions could be so much fun?
