In this Math Monday, we’ll cover one of my favorite math activities - MATH: Unit Price. Calculating unit price is a practical skill that students can immediately use as a valuable shopping hack. It’s also timely, as the news is filled with stories about inflation, cost of living, and shrinkflation. By calculating unit price, students can keep an eye on how much their purchases really cost. 

The Activity: 

Students practice calculating unit price using real-world examples of shopping for groceries and school supplies. 

The activity includes an example problem with Edpuzzle video, practice problems, and reflection questions. At the end, students consider why buying the package with the cheapest unit price might not always be the best real-world decision.
