Number Line Basics
A number line is a straight line with numbers placed at equal intervals along its length.
Number lines help us visualize numbers and understand how they relate to each other. They're like a map for numbers!
A number line shows numbers in order from left to right, with smaller numbers on the left and larger numbers on the right.
Number lines are useful for:
- Counting forward and backward
- Understanding number order (which numbers come before and after)
- Comparing numbers (greater than, less than)
- Adding and subtracting
