Calculating Unit Rates

When you begin the Shopping for Deals: Unit Rate Performance Task worksheet, you step into a real‑world shopping scenario instead of just solving numbers. You’re given several products or bundles with different prices and sizes, and your job is to figure out which one gives the best value. Rather than guessing or eyeballing the price tags, you calculate unit rates—like cost per item, cost per ounce, or cost per kilogram—and compare them carefully. This turns a normal trip to the store into a smart math investigation.

This worksheet guides you through calculating unit rates step by step. You learn to divide the total cost by the number of units to find the cost for exactly one unit. For example, if a 12‑pack costs $18, you compute $18 ÷ 12 = $1.50 per unit. Some problems present snacks, stationery, or household items with different pack sizes. Others use time or distance contexts to show how unit rates help compare options in non‑shopping situations. Each problem builds your reasoning skills and helps you think like a careful shopper or planner.

As you work through the tasks, your logical thinking and decision‑making grow stronger. You might see that a larger package looks cheaper, but the unit rate proves otherwise. You learn to read information, choose the correct numbers to divide, and interpret the result in context. Some questions even ask you to justify why one choice is better or how much money you’d save. Every correct comparison boosts your confidence and shows that math helps with everyday decisions.
