Marking on the number line
You learn to put a number in the right place on a number line.
How to work it out
- Find the big mark just before your number.
- Look how much one small mark is.
- Count the small marks forward until you get to your number.
Place 38 on the line
- Find the big mark before 38: that is 30.
- One small mark is worth 1.
- Count on 8 marks: 30 + 8 = 38.
