What examiners actually ask

Mixed Operations appears in 29 of our 338 ready papers (163 tagged questions). It averages 5.6 questions a paper worth about 2.39 marks each. The typical question allows around 24 sec. It appears in 3 CSSE papers we hold.

Mixed-operations questions deliberately combine more than one calculation. Papers may present a single expression with several operations, or a word problem that needs multiply-then-subtract style thinking. Children who grab the first two numbers and add them lose marks before the real work starts. Teach operation spotting first: underline verbs and symbols, decide the order (BIDMAS when needed), then compute. These tags also catch “add and multiply” drills that sit between pure arithmetic and word problems. Practise writing a one-line plan before the working so method marks survive if arithmetic slips. Link this hub to BIDMAS and the four operations pages when a report shows mixed-operation weakness.
