Exploring Stem-and-Leaf and Dot Plots in 5th Grade Math

Mr. Sanchez's lesson focuses on solving one and two-step problems using data from dot plots and stem-and-leaf plots. The video begins with an introduction to Louisa's race data problem, followed by a detailed analysis of both dot plots and stem-and-leaf plots. The lesson includes solving additional problems related to the race data and concludes with a summary of the key concepts covered.
