Lesson details
Key learning points
- Identify the next and previous whole numbers to the number being rounded.
- Identify which whole number is nearest to the number being rounded.
- If the value of the tenths is 5 or greater then round to the next whole number.
- If the value of the tenths is less than 5, round to the previous whole number.
Keywords
Multiple - A multiple is the result of multiplying a number by an integer. For example 2 × 5 = 10 so 10 is a multiple of 2 and 5.
Next - Something that comes after something else.
Previous - Something that comes before something else.
Rounding - Rounding means making a number simpler but keeping its value close to what it was.
Common misconception
Pupils say the previous multiple of one as a whole before e.g. previous multiple of 3.4 as 2 or 2.4
Place the number on a number line and clarify the whole numbers it sits between.
