Dividing Decimals and Visual Models

Natalie Rhodes introduces a 5th-grade math lesson focused on dividing decimals by whole numbers using visual models. The lesson includes solving a problem about saving money on lemonade by comparing individual and group purchases. It also covers dividing trail mix using base 10 blocks, emphasizing the use of visual models to understand division. Students are encouraged to apply these methods to solve similar problems independently.
