About the Junior Mini Mathematical Murder Mysteries (Ages 7-11)
Here are our top reasons to buy the Junior Mini Mathematical Murder Mysteries (Ages 7-11):
- 16 detective-style maths mysteries for children in Years 3 to 6, ages 7-11

- Written by Jill Whieldon and published by Tarquin
Your child, somewhere in Years 3 to 6, gets 16 crimes to solve, and the maths is the only way in.

Each case in this primary maths workbook uses the number work, shapes and data handling your child meets in class. The book spans Years 3 to 6, so you start at the level your child needs now. A confident Year 2 child who wants a stretch can join in.

There are 16 mysteries in this printed workbook, each a short case with questions to work through. In one, your child solves negative number calculations and then uses logic to pin down the time and place. In another, six suspects' statements hide two arithmetic errors.
The puzzles reward careful checking, so your child goes back over the working instead of rushing on. The topics are the ones the KS2 SATs cover, though nothing here reads like a test paper. A Year 7 child steadying the basics will enjoy the cases too.
