Lesson Plan : Graphing and Probability

Teacher Name:
 Jessica Bolen
 Grade 3

 Graphing and Probability
 Students will graph, classify, count, round, use probability, ratios, and estimating. Academic Content Standard: Data Analysis and Probability Standard. Benchmarks: A. B. C. F.
 Students will be able to: count, sort and classify m&m's by their color. Students will graph their data on a bar graph. Students will use the data to figure ratios and determine probability.
 Students will participate in a hands on activity using cooperative learning while collecting, analyzing, and interpreting data.
 Small bags of M&M's. Paper, pencil, rulers and markers.
 Each student will be given a small bag of M&M's. Teacher will review sorting and classifying as previously done in the class.
 Students will work alone to classify and sort their M&M's. Students will then graph their information on a bar graph. After illustrating their results students will form small groups to compare their findings. Next students will need to be in groups of 4-6 to combine their data and make a new graph.(This lesson could be broken into the course of the week depending on time.) Finally the groups could come together to combine all information to make a whole class bar graph showing the results. Students can then as a class discuss the results and make ratios of the different M&M's. The class can then use probability activities to see how many of each color is likely to be found in bags of ten or twenty M&M's. Have the class test out the probability. Then enjoy the M&M's.
 Teacher should be walking the room monitoring class discussion on the similarities and differences in the graphs.
 The teacher may need to group students struggling with the concepts with students who are confident with their math skills and make sure all students are actively participating. Students who are not allowed to have chocolate may need a special snack while the other classmates are enjoying M&M's.
Checking For Understanding:
 Students could complete a worksheet using the class graph to write ratios. Oral assessments while the teacher is circulating the room. Have students write a description of the project and what they learned by completing it.
 As a class review why it is important to understand and know how to read graphs. Discuss place and ways ratios and probability can be used in real life situations.
