Thirty-two column addition questions across four pages for Year 3 maths. Pupils warm up without exchanging, tackle one exchange with questions like 349 + 135, then double exchanges such as 147 + 285, and finish with four missing-digit puzzles. Every answer is in the key at the back. Covers the England National Curriculum columnar addition objective.
