State Board of Education-Adopted Grade Two Page 34 of 45 552 Example: How many different ways can you make 37¢ using pennies, nickels, dimes, and quarters? Example: How many different ways can you make 12 dollars using $1, $5, and $10 bills? 553 (Adapted from Arizona 2012 and N. Carolina 2013) 554 555 556 557 558 559 560 Measurement and Data 2.MD Represent and interpret data. 9. Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Show the measurements by making a line plot, where the horizontal scale is marked off in wholenumber units. 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 4 using information presented in a bar graph. Students use the measurement skills learned in earlier standards to measure objects and create measurement data (2.MD.9). For example they measure objects in their desk to the nearest inch, display the data collected on a line plot, and answer related questions. Line plots are first introduced in this grade level. A line plot can be thought of as plotting data on a number line. For example: 561 562 563 564 565 Students draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. They solve simple put-together, take-apart, and compare problems using information presented in a bar graph. (2.MD.D.10) 566 4 See Glossary, Table 1. The Mathematics Framework was adopted by the California State Board of Education on November 6, 2013. The Mathematics Framework has not been edited for publication.

In second grade, students represent data on a picture graph or bar graph (with single-unit scale) and interpret the results. Students organize, represent, and interpret data with up to four categories. In second grade, picture graphs (pictographs) use symbols that represent single units. Pictographs should include a title, categories, category label, key, and data. Students use data to pose and solve simple one-step addition and subtraction problems. The use of picture graphs and bar graphs to represent a data set (2.MD.D.10) reinforces major work at the grade in the cluster “Represent and solve problems involving addition and subtraction” and provides a context for students to solve related addition and subtraction problems (2.OA.A.1▲). Example: Students are responsible for purchasing ice cream for an event at school. They decide to collect data to determine which flavors to buy for the event. Students decide on the question, “What is your favorite flavor of ice cream?” and four likely responses, chocolate, vanilla, strawberry, and cherry. Students form two teams and collect information from different classes in their school. Each team decides how to keep track of the data (e.g., tally marks, in a table, check marks). Each team selects either a picture graph or a bar graph to display their data. They create the graph using paper or a computer. Examples of graphs are provided below. Team A: Bar Graph The Mathematics Framework was adopted by the California State Board of Education on November 6, 2013. The Mathematics Framework has not been edited for publication.
