Math practice becomes a detective adventure in Junior Detective Agency: Math Mystery Case Files. Young detectives take on 5 exciting mystery cases, each filled with suspects, clues, puzzles, and mathematical evidence.
But there is only one way to crack each case—solve the math correctly and use the answers to eliminate the suspects.
Every investigation includes 4 different clue challenges, giving children a fun reason to practise important early math skills while thinking carefully about what each answer means.
Inside, young detectives will tackle activities involving:
• Addition and subtraction
• Adding three numbers
• Missing numbers
• Word problems
• Elapsed time
• Maps and directions
• Coordinates and grids
• Number properties
• Balanced equations
• multi-step number challenges
After solving all four clues, children complete their Case Report, name the culprit, and collect a secret letter.
Solve all five cases and the letters unlock one final mystery!
Designed for Grades 1–2 and ages 6–8, this large 8.5 × 11-inch activity book combines math practice, logical thinking, reading comprehension, and problem-solving in an engaging screen-free format.
Full solutions are included at the back, making it easy for parents, grandparents, home schoolers, and teachers to check each investigation.
