This Year 3 Measuring and Comparing Mistake Investigators resource is designed to develop children’s problem-solving and reasoning skills by encouraging them to identify and explain mistakes.

For each objective, there are four carefully structured questions: one with a correct answer and three with mistakes. Children are challenged to spot the error, find the correct answer, and explain their thinking.

The resource is ideal for group work, sparking discussion and collaborative learning. It focuses on key objectives such as comparing lengths (m/cm/mm), measuring and comparing mass (kg/g), and measuring the perimeter of simple shapes.

If you’re looking for a resource that builds confidence and deepens reasoning, this is the perfect choice!
