Grade 3 Common Core Math: Data and Graphs

Grade 3 Common Core Math: Data and Graphs gives students everything they need to organize, graph and read data, in the order a teacher would teach it. Students sort buttons and survey answers by two and three attributes in two-way tables, Venn diagrams, Carroll diagrams and tree diagrams. They plan questions, collect data by watching, testing and asking, and turn tallies into frequency tables. Then they draw pictographs with a key and bar graphs with scales of 2, 5 and 10, each with a title, labels and a source, and read graphs at three levels: reading off a value, comparing, and making a decision.

The mean is taught by leveling out towers of cubes until every tower is the same height, before students add and share. Two pages use real snowfall data from NOAA for January to May 2026: students graph the snowy days in Duluth, Minnesota, then compare Burlington, Vermont, with Portland, Maine, using the mean and the mode. Probability pages use the five likelihood words to predict, test with a bag of tiles, and decide, and a class activity asks whether another Grade 3 class will have the same mean and mode as ours. A two-page class data investigation takes students from their own question to a graph they present.

Inside: teacher notes with a teaching order over about four weeks, timing, materials, differentiation, the common misconceptions and a map from standard to pages; five teaching pages with worked examples; ten practice pages; four activities; an end-of-unit assessment; and an answer key with every answer worked out and checked. The scaled-graph pages line up with Common Core 3.MD.B.3; the mean, mode and probability pages go a little beyond Grade 3, and the notes say where to skip them. Everything is black and white and nothing depends on color. The free sample is the teacher notes and the pictograph practice page.
