One of the most-missed easy marks in 11+ maths. 4+6×2 is 16, not 20 — and papers test exactly that reflex several times.
What 11+ bidmas / order of operations questions cover
At 11+ level, bidmas / order of operations means bracket-first evaluation and multi-operation expressions. Our free worksheet library grades every topic across four tiers — Foundation, Developing, Secure and Greater Depth — so a child can enter at their level and climb.
How to use the worksheets
- Diagnose: one Secure-tier sheet, unaided. Score under 70%? Drop a tier. Over 90%? Climb one.
- Little and often: 15–20 minutes daily beats a weekend marathon — retention lives in the gaps between sessions.
- Review errors out loud: the child explains what went wrong; you resist explaining first. Self-diagnosis sticks.
- Fold into mocks: once a topic hits Greater Depth, let full timed mock papers keep it warm rather than more isolated drilling.
