## 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

Estimate - To find a value that is close enough to the right answer, usually with some thought or calculation involved.

Compare - You compare to find out what is the same and what is different. You can compare numbers to find out if one is greater than or less than another.

Midpoint - The middle of something. The point halfway along.

Number line - A line with numbers placed in their correct position.
