A wonderful starter lesson for 2022 finding how to make the numbers 1 to 25 with the four digits 2022 and mathematical symbols and it is actually possible!
Bonus marks can be given for using the four digits in the order 2022 and an extension idea is included which involves continuing the problem to find the numbers 26 - 50. It is possible to find at least 15 of these 25 numbers.
This works well as a full class activity and pupils can initially work on their own, then share their solutions in pairs and then finally see if the whole class has found the 25 solutions between them.
