LESSON 4 Who Is Right?
A third-grade class did the experiment Kind of Bean. Tara and Kim were partners, and Mark and Jason were partners. They used the same container of beans and the same scoop. Each pair took their own sample. Their data tables are below.
The girls and boys compared their data. The girls said, “Oh, no! One of us must have done it wrong. Our answers do not match!”
The girls and boys compared their data. The girls said, “Oh, no! One of us must have done it wrong. Our answers do not match!”
