# Found Pounds

### Source Institutions

NCTM Illuminations

In this lesson, learners create memorable benchmarks for ounces and pounds by playing a scavenger hunt game in which they gain points for finding objects that weigh approximately an ounce or pound. Learners practice weighing objects and discuss why it is important to know the difference between ounces and pounds. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

#### Common Core State Standards for Mathematics:

• CCSS.Math.Content.3.MD.A.2: Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.(more info about this benchmark)
• CCSS.Math.Content.4.MD.A.1: Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two column table.(more info about this benchmark)
