Halving odd numbers and finding fractions of a number

Use these cards as a refresher in a starter or as a plenary to a lesson. Print them back to back so they have the answers on the reverse for self-checking. There are 16 questions for each set so you have more than one of the same question so children can become familiar with the process and how to solve them. Pupils take their first card and work out the answer - this can be checked on the back of the card. Then they move around the class and find a ‘partner’. They then attempt each other’s questions, check each other’s solutions using the back of the card and then find a new partner repeating the process.
