A number line is a visual representation of numbers on a straight line. This line is used to compare numbers that are placed at equal intervals on an infinite line. Zero (0) is considered to be the origin of a number line. As we move towards the right side of a horizontal number line, the numbers increase; as we move towards the left, the numbers decrease.
Number Paths
Number Paths
Number paths are great for younger children to learn how to count. They are an informal learning tool for games, fun and precursors to the concept of distance and length when using a number line.

How to Draw a Number Line
How to Draw a Number Line
Step 1: Draw a horizontal line with arrows on both ends.
Step 2: Choose a scale depending on the given number. For example, if you have to plot 5, then you can choose a scale of 1. If you have to plot 50, you can choose a scale of either 5, 10, or 25.
Step 3: Mark the points at equal intervals. So, if you have chosen 1 as the scale, then mark 0, 1, 2, 3, 4, and so on.
Step 4: Locate the given number. Mark it.
Number lines are an important way to represent numbers because they allow the concept
of a number to be expanded to decimals, fractions, and negative numbers, and they unify different kinds of numbers and present them as a coherent whole (Beckman, 2022). Depending on the grade you're working with as a teacher the introduction to number paths can be relatively an easier concept for students. They know how to count and learning to plot numbers is the new concept. My goal is to continue working on how to help students working on plotting those numbers with 5 or 6 digits.
