A trip to the supermarket or grocery store is usually a weekly and sometimes even daily event.  Bring your child along and keep them occupied with grocery store math activities that not only allow them to be involved with shopping for your family but also incorporate mathematics skills.

1. Cost of Meals

Step 1: If you’re planning a meal or even multiple meals, plan out the menu with your child before going to the store.
Step 2:  Make a list of items you will need and the quantity of each item.
Step 3: As you are collecting the items at the grocery store, have your child write down the cost of each item. For produce, make sure to weigh the items and have them determine the price before going to the cashier.

Note: Weighing items and determining total cost can be an ongoing activity throughout the supermarket for loose items that are priced by weight.

Step 4: Once you have returned home, your child can calculate the total cost of the meal and the cost per person in your family.

2. Daily, weekly and monthly amounts of customers

Ask the manager of a local store the average number of customers that come to the store each day. You can ask the manager together, or have your child ask independently if they are comfortable with doing so.  Using the answer they receive from the manager, have your child estimate the number of customers per week, month and even year.

Step 1: Using an item from your shopping list, find two brands of the same item in different sizes.
Step 2: Record the weight and price for each item.
Step 3: Calculate which one is the better buy based on price per unit.

4. Rounding Receipts

Step 1: Save all receipts from your shopping trip
Step 2: Have your child round each item price to the nearest \$0.10, \$0.50 and/or \$1.00.
Step 3: Calculate the total using each method. Compare.
