A hands-on maths mystery for your youngest learners. In “The Mixed-Up Shapes,” someone has muddled every shape and measurement in the classroom — and only sharp geometry thinking will sort the clues and reveal the culprit.

Across five evidence stations, students (ages 5-7) solve shape and measurement problems. Each correct answer rules out a suspect, a place, or a clue, until just one culprit remains. It’s a self-checking escape-room feel with the rigour of a full problem set — perfect for review, centres, early finishers, or a sub day.

SKILLS COVERED (Geometry & Measurement):
• Naming and sorting 2D and 3D shapes
• Identifying shape attributes (sides, corners, faces)
• Composing and partitioning shapes
• Comparing and ordering by length
• Logical reasoning and deduction

WHAT’S INCLUDED:
• Print-and-go student booklet (PDF) — 5 stations
• Full answer key (PDF) for instant marking
• Editable Google Slides version for digital or projected play

HOW TO USE: Print the booklet or share the Slides. Pupils work solo, in pairs, or in small teams, solving each station and crossing suspects off the board until they crack the case. The answer key makes it fully self-checking.

PERFECT FOR: maths centres, review and revision, early finishers, enrichment, substitute/cover lessons, and end-of-unit fun.
