#### Countdown Challenge: Shadow Sleuth

In this shadow sleuth activity, students use proportions and indirect measurement to determine the measurement of given objects. This one-page activity contains three problems.

Lesson Planet

#### Measuring Beads

Students compare the weight of the students's favorite soft toys directly and then indirectly using beads.

Lesson Planet

#### Measuring Up

Proportional reasoning, ratio, and indirect measurement come to life in a series of seven lessons. Learners will convert measurements into customary and metric units. They also use real-world examples to solve problems involving scale as...
