Lesson details
Key learning points
- Identify the next and previous tenths to the number being rounded
- Identify which tenth is nearest to the number being rounded

Common misconception
When recording which multiple of 0.1 a number is nearest to, pupils may forget to include the ones.
Make sure pupils have plenty of opportunities to continue counting and rounding with multiples of 0.1 beyond one whole.
