Lesson details
Key learning points
- Knowing where multiples of 100 are placed on an unmarked number line supports in positioning 3-digit numbers accurately.
- Marking halfway steps helps to estimate the positions of numbers.
- Counting in steps of 1, 10 and 100 helps us to position a number on a number line.
Keywords
Estimate - Estimate means finding a value that is close to the answer.
Position - Position means where something is located.
Unmarked - Unmarked means that many of the steps on a number line are not given.
Common misconception
Pupils may struggle with positioning numbers on 0-1,000 lines.
Relate the positioning of numbers on 0-100 number lines with 0-1,000 number lines (e.g. 19 and 190, 37 and 370).
