Number sense for algebra

Match numeric expressions. Use properties of + x division with number examples to prepare for simplifying algebraic expression. Self-assessment and self-check - when the Santa's train is assembled correctly, you can read a joke. No calculator is needed, but it can be allowed to speed up the process with a curious class. there is a couple of tasks that need long division and column (or other ) multiplication ; a couple of tasks with negative numbers, powers and fractions - again, useful to assess y11 and refresh what they remember about operations with numbers. I used it as a preparation for teaching simplifying algebraic expressions too and to help year 11 to review and make sense of the same topic. I am sure it can be used for a mental maths practice with top year 7. I hope you find it useful.
