Perfect for St. Patrick's Day!
Using Bar Graphs, Tally Charts, and Picture Graphs (Pictographs)
[ ] 1 box of Lucky Charms Cereal (or more). It is probably a good idea to pour the cereal in a small bowl or have them packed in small bags to make it easy to pass out.
[ ] White Glue per student or table
[ ] Pencil
[ ] Tally Chart, Bar Graph and Pictograph Worksheets (from this packet)
[ ] A plate or bowl for sorting the marshmallows and the plain cereal
1. Introduce what graphing is. What is it used for?
2. Explain what the term data means.
3. What things can data help us see? How is data used in every day life? When did you last use data?
4. Explain that every graph needs a title and a scale (or key),
5. Have students sort their bag/bowl of Lucky Charms. Students should remove the plain cereal first, then sort the marshmallows by type (hearts, blue moon, shooting stars, etc.)
6. Students will then collect data by filling out the tally chart.
7. From the tally chart, students will be able to complete both pictograph and bar graphs.
8. Students (or the teacher) can select the scale. Each marshmallow can represent 1 or each marshmallow can represent 5 in the box. Choose the scale that is most appropriate for the quantity of cereal per student.
Common Core State Standards and Lesson Objective
2.MD.D.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph.
3.MD.B.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
