Unit Cost and Actual Shopping

I previously shared that grocery shopping has a lot of tasks that are overlooked. One is working with unit costs. There are two math tasks related to unit cost, interpreting what a unit cost is and computing the total cost for buying multiple items.

When I take a student into a grocery store to work on unit costs, where is what I do. I start with a pack of items (photo on the left) and ask the student to compute the cost for 1 item, in this case, “what is the price for the pack of chew sticks, how many in a pack, how much for 1 chewstick?” Then I prompt the student to compute the total if he buys 3 packs. This allows the student to differentiate between the two tasks. The cost per items is easier to grasp and then is followed with the same prompts for a jar of sauce (below right).

I then have the student compare unit costs for the large vs the small jars and ask, “do you want to pay $4.99 per ounce or $5.99 per ounce.” This language is more accessible than “which is a better deal?” You can work towards that language eventually.

These tasks can be previewed at school with a mock grocery store. The price labels can be created on the computer.

Counting Money as a Game

The Allowance Game is retail game tailored to students who are learning to count money.

 

I revised it to make it more authentic and more functional.

  • I changed some money amounts to necessitate the use of pennies (see below)
  • I use real dollars and cents to provide more opportunities to handle real money
  • I differentiate by creating different task demands. For example
    • I was using the modified version with 2 clients
    • One was learning to count out dimes and pennies only, but could manage ONES simultaneously
    • This student would also be provided a coin chart I use to teach students how to count with coins
    • The other was practicing with ONES, and all coins up to a quarter
    • I collected data on a data sheet – 1 per student

The students loved playing the game, it was engaging so they practiced the counting out money, I was able to collect data, and I was able to differentiate. When I co-taught a Consumer Math course, I would assign a para (instructional assistant) to facilitate the game with a couple students and to collect data.
