Frequency Tables, Dot Plots, and Stem and Leaf Plots

This week we focused on ways to collect and organize data. We began by making frequency charts and dot plots, which aren't new for 4th graders. We simply reviewed their set-up and purpose. We then moved to stem and leaf plots. These are new for 4th graders, so we spent a whole math block just creating them with made-up data. The next day we brought in some already-made stem and leaf plots so that we could really evaluate them to determine what they represented.
