Proportional Relationships in Math

Penelope, in her math lab, explores proportional relationships using tables, proportions, and graphs. She demonstrates how to create a table for mixing dyes in specific ratios and uses Harold the beetle's speed to illustrate proportions and graphs. Penelope also shares her project on curing math phobia, highlighting the use of scale factors. The session concludes with Penelope's farewell.
