How to Use a Number Line
A number line shows numbers in order, evenly spaced along a line. On these worksheets, every number line counts with the same step, the same jump from one number to the next. Children look at the numbers that are given, work out the step, and fill in the missing numbers by counting forward or backward.
How do the levels work?
The first levels count by ones, up to 20 and then up to 100. The next levels skip count by 2, 3, 4, and 5 up to 100, and the last one counts by tens up to 1,000. Every number on a line is a multiple of its step, just like in a multiplication table.
Tips for number lines
- Find two neighboring numbers first: the difference between them is the step.
- Count forward to fill a box on the right, and backward to fill a box on the left.
- Check your answer with the next number given on the line.
- Say the numbers out loud to learn the skip counting patterns by heart.
