How Coupons Teach Math in 12 Different Ways

Here’s a list of twelve ways coupons teach math. This math teacher uses coupons to teach students how to improve their math skills and live frugally at the same time with couponing.

This is probably an obvious one, but as you add up your groceries, you’re performing addition! When you subtract coupons and sales, you’re performing subtraction! This is an easy way to teach math with coupons.


When you’re doing it with money, it makes it easier to explain to the kids why the decimal point needs to line up! It makes no sense for you to add $2.50 and $3 to get $2.53.


This is another easy way to see how coupons teach math! If bags of potatoes cost $2 each and you need to buy four bags, how much will you pay? (Tip: the answer is $8.)


Division is best used in couponing to discover unit price and find out if you’re really getting a good deal or not.


If your bag of grapes weighs 1.3 lbs, and it costs $.92 per lb, how much money will your grapes cost? This is a perfect time to demonstrate multiplication with decimals!

Multiplication with Decimals

This is the same as regular division, although when you’re calculating unit price, you are most likely going to be working with decimals instead of whole numbers.

Being able to move between the different measurements in order to compare prices is very important in couponing!
