Use these Christmas calculations to challenge your pupils' understanding, ability to reason mathematically and algebraic thinking in a fun and engaging way!
Using images to represent numbers, children use what they know to discover the value of the images, e.g. x + x = 4 (where x is represented by a Christmas tree). They need to understand the meaning of =, + and - signs and the relationship between addition and subtraction. The calculations include doubles and decomposition of number 10 into pairs.
There are 3 pages of progressively more difficult calculations, as well as 3 pages with the numbers given in the top right hand corner for children requiring more support. As an extension, children could create their own reasoning challenges or write top tips to help others work out the calculations.
