Lesson Details
Key learning points
- The position of numbers can be estimated on unmarked number lines using an understanding of relative size.
- The midpoint, five in this case, should be marked to support positioning
- We can compare numbers on a number line by looking at how far away from other numbers they are.
Common misconception
Children may find it hard to draw their own number lines.
Place the first, last and midpoint numbers first and use fingers or cubes to space the other numbers out equally.
Keywords
