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.
One resource I use to teach bar graphs is the Lakeshore hands on math tray. Lakeshore also has trays for Venn Diagrams, sorting, patterns, and counting. These trays are designed for small manipulatives like counting bears, Unifix cubes, or foam counters. If your school does not have instructional money available to purchase these trays, they can be easily made using 2-3 ice cube trays glued to a base or taped together.
When I teach students about graphs we first collect data by reading an article or taking a class vote, for example. We record data and then use manipulatives to represent the data on the bar graph. After this whole group learning, students can use graph paper to draw and color the bar graph as independent practice. I recommend taking a vote related to the manipulatives for the first lesson. For example, students could vote on their favorite color or plastic animal. Rubber stamps are also good for making pictograph-type bar graphs on paper.
