Resource of the week: Christmas adding puzzle

Looking at my stats I can see that everyone is very busy with Christmas assemblies, shows, shopping, eating, drinking etc so I will shortly be joining you all and have a few days off. I will leave you with a little puzzle in case you have nothing better to do!

Put the numbers 1, 2, 3, 4, 5 in the bottom layer of baubles on the Christmas tree. The next layer is made by adding the pairs of numbers below and so on up to the top.

The numbers on the bottom row can be put in any order – what order will give the highest possible total at the top?

Answer is given for those who have eaten too many mince pies.

Happy Christmas
