A problem solving murder mystery! The mystery is set at the world cup where a dead body has been found in the England team’s changing room. Children need to solve five clues and eliminate suspects from a list until only the killer is left. The clues involve recognising number patterns, cracking a code, working out doubles of numbers and coordinates. Suitable for upper KS1/First level and lower KS2/Second level. A fun and engaging activity which works well in mixed ability pairs. Answers included for self/teacher/peer assessment.
