## Grocery Store Math

Most older children truly dislike going to the grocery store.  However, grocery shopping can be the perfect opportunity to introduce your child to real life cases where math is important and useful.

## Estimating

Most people at the store have a general idea of how much money they can or want to spend.  Ensuring that they stay below that amount means that a person must have an idea of how much money the items in their cart cost.  Have your child practice estimating by rounding the price of each item you put into your cart and then adding the rounded numbers.  Make it a game to see how close they can get to the actual total of your groceries at the end of the trip.

## Making change

When you put an item in your cart, have your child tell you how much change they would get back if they bought that item with a five, ten, or twenty dollar bill.  You could also make this a little simpler for a child by only working with the dollar amounts, not the cents.

## Multiplication

Have your child tell you what multiple pounds of either fruits, vegetables, or meat would cost based on the price per pound cost.  For example, if grapes cost \$2.00 per pound, how much would 3 pounds cost? (\$6.00)  This could also be practiced with multiple items. (If these apples cost \$0.30, how much would 10 apples cost?)

## Division

Your child can use the cost of items packaged together to find the individual cost of one of the items. If a package that contains five boxes of macaroni and cheese costs \$2.50, then one box would cost \$0.50. (\$2.50 divided by 5)

No matter what age your child is, the grocery store is a great place to practice using the math that he is learning every day.  Grocery store math – part 1 has some great ideas for math activities to do with younger children in the grocery store.
