Although we may not realise it, maths is all around us during the festive period, from working out the timings of the turkey to (miscalculating) the length of fairy lights needed to wrap around the tree! 

Check out our festive maths questions! They’re perfect as a classroom activity, or for bringing in the festive season at home.

Question 1: Merry mental maths

  • Multiply it by 3
  • Divide by the number of ‘Geese a-laying’

Question 2: Santa’s sleigh
