World Book Day – Numeracy

Recent Posts

The children used and applied their maths knowledge in this lesson to solve a murder mystery! The police had been called to investigate the murder at a hotel. As Chief Detective Officers, the children had to solve the crime.

There were 32 suspects—all of them an outlaw in the Wild West.  Each clue was left in a different code so that only the children, with their amazing code‐breaking skills, would be able to solve them all.

They could tackle the clues in any order. Once they had solved each clue they would be able to eliminate some of the suspects from their inquiries. Each clue would remove half of the suspects from the list, until they were left with just one.
