Addition and subtraction look basic and still decide papers when place value slips. 11+ questions mix column methods, mental strategies, and worded “how many more / left” stems. Independent papers often hide several operations in one story; grammar-style papers punish careless regrouping. Children who invert subtraction (smaller minus larger) or forget a carry lose marks they expected to bank. Practise both directions: compute cleanly, then estimate whether the answer is sensible. Pair this hub with word problems and money so the arithmetic survives messy wording. A thirty-second check — “is this roughly the right size?” — catches many expensive slips before they cost the mark.
