How do you teach proportions?
To introduce proportions to students, give them tables of equivalent rates to fill in, such as the one below. This will help them learn proportional reasoning. Work with these tables (first using easy numbers) until the students get used to them. You can tie in some of them with real-life situations.
What does proportion mean in math?
Definitions: A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 0.25 are boys (by dividing 1 by 4)

A good way to work with a ratio is to turn it into a fraction. Be sure to keep the order the same: The first number goes on top of the fraction, and the second number goes on the bottom. You can use a ratio to solve problems by setting up a proportion equation — that is, an equation involving two ratios.
