A 20-year-old with Down syndrome is preparing to purchase five items from a list. Which math skill is most likely needed for budgeting the purchase?

• A. Using a handheld calculator to compare prices and ensure that the total cost of the five items is within budget
• B. Rounding the cost of each item selected to the nearest dollar and adding those amounts to estimate the total cost of the items
• C. Practicing how to count out one-dollar bills to pay for the purchase at the checkout counter
• D. Determining whether the balance on a debit card will cover the cost of the purchased items

Answer: (B)

Estimating costs by rounding to the nearest dollar is a practical budgeting skill. By rounding each item’s price and adding those rounded amounts, you get a quick, easy total that shows whether five items will fit within the available money. This approach keeps planning simple and helps someone decide early if they need to adjust selections before shopping. Using a calculator for exact totals or practicing counting cash are useful for later steps, but for the purpose of budgeting upfront, rounding and estimating the total is the most efficient way to gauge affordability. Checking a debit balance or paying with cash are about after-the-fact handling, not the planning stage.
