What is a double number line?
A number line is a visual aid and a simple and effective way to help children understand numbers, practice basic addition and subtraction, and learn fractions.
Double number lines are an excellent tool, for example, when given a price for a quantity of an item. And then, the student needs to know the price for more items.
How are the double number line diagrams used?
Double number line diagrams are used as a visual aid to solve math problems. The two lines on the diagram represent two different numbers.
And the double number line shows the equivalent ratios.
Example 1: Price of flowers
One flower costs $5.
So the top line of the double line shows the number of flowers, and the bottom line indicates the price.
Example 2: Recipes – eggs and flour
Let’s say you’ll need to make a bigger cake. But your recipe shows only how to make a small cake. To make the small cake you’ll need, for example, 2 eggs and 1 cup of flour. If you want to make a bigger cake using 6 eggs, how many cups of flour do you need?
The top line shows how many eggs are used for the recipe, and the bottom line will show how much flour will be needed.
The top line will be 2, 4, 6, 8…
And the bottom line is 1, 2, 3, 4…
The double number line diagrams show perfectly the numbers that represent equivalent ratios. Just check the place where the tick marks match.
Example 3: How many batches of powdered drink mix can you make?
If you need 3 teaspoons for every 2 cups of water, how many cups of drink mixtures can you make with 15 teaspoons of the powdered drink mix? How many teaspoons of powder is needed if you want to make 6 cups of drink mix?
The top line shows the teaspoons: 3, 6, 9, 12, 15, 18…
And the numbers on the bottom line represent multiple batches/the cups of water needed: 2, 4, 6, 8, 10, 12…
Number lines are a helpful visual aid for basic math operations, fractions, and solving problems. Double number line diagrams offer an even more precise way to see equivalent ratios. Printable versions of these helpful tools can be found on this page for your convenience. I hope you find them helpful!
