A quick starter on finding 10 or 100 more or less for Year 3 maths. Six questions in two rounds: Quick Fire jumps such as 10 more than 452, then Number Chains that add and subtract in steps, including a mystery start number pupils work out backwards. The answer key covers all six items. Matches the England National Curriculum objective on finding 10 or 100 more or less than a given number.
