## Budgeting is a challenging topic for many students with special needs. The process has many components, multiple steps, and involves application of money and shopping math topics. This post describes an activity to develop competence in budgeting by shopping for a food for a week with a money limit.

The activity is presented on a Google Doc and can be completed with online shopping at a grocery store of choice or at Stop and Shop. A gift card image is used to lead into a discussion or lessons on balance. This is a preview of a full budget activity shared on another post.

### Identifying Food Items

The first step is to identify the foods to eat. To keep it simple, only the meals for a single day are identified and will be extrapolated to cover the whole week. This will not take into account snacks to reduce the task demand. This also leads into lessons on nutrition, e.g., identifying macronutrients and what they provide our bodies.

### Shopping

The student identifies the food item for each meal and enters the item, cost, and of servings. A discussion or minilesson on number of servings may be conducted first.

After shopping, the student determines if there are enough servings to cover all 7 days. If not, the number packages (bottles, etc.) are determined. This can be done by multiplying by 2, 3, 4 until more than 7 is computed. Then the total cost for the food item is computed.

Then the grand total is computed at the bottom. This leads to a discussion about the budget as the student compares the total with the amount or balance on the gift card(s).

## Shopping is Dense with Math Tasks

I recently worked with a student on an online grocery shopping activity – finding ingredients for mac and cheese. We had the ingredients listed in a column on a Google Doc (allows both of us to edit the doc simultaneously) and then he cropped and pasted a photo of each ingredient (see photo below). The goal was for him to identify the total he need and the total cost in planning for actual shopping or to continue with the online shopping. Note: he wasn’t actually buying anything at this point but this was a step in preparing him to do so.

This activity is dense with math tasks and shopping related tasks. The math tasks include the following:

• Identify the price (vs quantity of the item or unit price).
• Interpret the quantity for the ingredient.
• Identify the units (oz and cups)
• Convert units
• Compare amount in box with amount needed.
• Determine how much more is needed, if any.
• Compare choices before selecting the item, (Barilla Pasta vs another brand).

To convert units, the “mathy” approach can be used or the student may simply use an app. For this student we chose an online unit converter (see below). This is more complicated that it appears. The student must choose the units and the order (in this case convert cups to ounces or vise versa), distinguish between imperial and US cups, understand that you enter the quantity (the search results in 1 US ounce appearing by default), and then interpret the decimal (keep in mind the ingredient quantities are in fractions).

Life skills math is more complex and challenging that parents and educators may realize. As a result, the planning for developing these skills should begin much sooner rather than later – not to mention the actual logistical tasks of shopping, e.g. finding an item in the grocery store.
