Lesson details
Key learning points
- Identify the digit in the place value place the number is being rounded to - then find the previous and next multiples.
- Then identify the digit to the right of this - this is the critical digit.
- If the critical digit is a four or less, we round to the previous multiple.
- If the critical digit is a five of more, we round to the next multiple.
Keywords
Round - When we round, we make a number simpler but keep its value close to what it was. The result is less accurate, but easier to use.
Critical - Something that is critical has crucial importance.
Common misconception
Mistakes may be made when identifying the previous multiple of the power of 10 or when giving the rounded answer (missing off any digits that have a larger value).
Use numbers lines, the stem sentences and learning about the critical digit to support children to identify previous multiples and when giving their answer.
