The Triangle worksheet groups the addition questions followed by the subtraction questions. Pupils work mainly with three-digit numbers while becoming familiar with missing values in different positions.

⭕ Circle – Middle-ability level

The Circle worksheet mixes addition and subtraction more fully and varies the position of the missing number. This encourages pupils to decide which operation or inverse operation is needed.

⬜ Square – Higher-ability level

The Square worksheet introduces a wider number range, including totals greater than 1,000, while continuing to vary the operation, equation structure and position of the missing value.
