Christmas Maths Mystery KS2 Worksheets, Whodunnit Problem Solving for Year 3 to 6 with Answers

Santa's golden sleigh bells have vanished the night before Christmas Eve! Eight North Pole workers were near the workshop. Seven are innocent. Your pupils solve seven maths clues, cross off a suspect with every correct answer, and catch the thief.
