Detective Workbook Guide and Answer Key: Secret Codes, Logic Clues, and Sequences

This teacher guide supports three companion detective workbook activities with instructions, worked examples, puzzle checks, and an answer key. Children practise decoding number-to-letter messages, reasoning from logic clues, and completing number or letter sequences to solve a mystery. Use it to model each task, pace the activities in order or choose one for a lesson, and help children explain evidence rather than guess. Keep the answer key covered until children have completed each activity.
