No match:Rounding
Twenty-five numbers to round to decimal places and significant figures, ending with zeros that must stay (7.996 to 2 d.p. is 8.00). Cross each answer off the bank; the five with no match give the letters for an anagram. The bank holds 35 for 3456 to 2 s.f. and the answers you get by cutting off instead of rounding.
A free key stage 3 and GCSE number puzzle with answers, spec code N15. It goes with the lesson on rounding to decimal places.
