Double number lines (also known as ‘stacked number lines’) consist of two single number lines with corresponding pairs of values lined up.Double number lines provide a way to visually compare two quantities and are a representation that can be applied to many different mathematical situations.

What is the definition of a double number line?
Definition: Double Number Line Diagram. A double number line diagram uses a pair of parallel number lines to represent equivalent ratios. The locations of the tick marks match on both number lines. The tick marks labeled 0 line up, but the other numbers are usually different. Figure 2.3.1.
What is the difference between a number line and a double number line?
A double number line shows each of the quantities on its own number line, with corresponding pairs of values lined up; the units on each number line are not the same unless there is a 1:1 ratio between the quantities.
How is a double number line similar to a ratio table?
Both double number lines and tables can help us use multiplication to make equivalent ratios, but there is an important difference between the two representations. On a double number line, the numbers on each line are listed in order.For this reason, sometimes a table is easier to use to solve a problem.
What is the double of 4?
8

What is the difference between a double number line and a table?
A double number line dictates the ordering of the values on the line, but in a table, pairs of values can be written in any order.
Why would double number line diagrams be difficult to use in some situations?
Sixth graders interpret and solve ratio problems. Understand ratio concepts and use ratio reasoning to solve problems.3: Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
Why is a number line important?
Number lines are important because they present numbers in real life. Primarily, because they enable negative numbers to be represented in a way that made sense.This result meant that the number line became a versatile and powerful visual tool to help students understand numbers.

What is a ratio table?
A ratio table is a structured list of equivalent (equal value) ratios that helps us understand the relationship between the ratios and the numbers. Rates, like your heartbeat, are a special kind of ratio, where the two compared numbers have different units.
How do I teach my child the number line?
Basic Number Line Skills
- Find the dot marked on a number (and name the dot)
- Place a dot at the desired location.
- Find the desired number below the number line’s tick mark*
- Add the missing number.
- Learn the numbers to the right are higher than numbers to left.
- Determine which number is greater than, less than or equals.
Why do kids use number lines?
Using number lines can help children to develop counting skills without the use of an aid. Children should also be able to count, read and write numbers to 100 in numerals and also be able to count in multiples of 2s, 5s and 10s.
