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.
Previous - Something that comes before something else is known as the previous thing.
Next - Something that comes after something else is known as the next thing.
Rounding - Rounding means making a number simpler but keeping its value close to what it was.
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.
