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
- If the value of the hundredths is 5 or greater then round up to the next tenth
- If the value of the hundredths is less than 5, ignore the hundredths and round down to the previous tenth
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.
Keywords
