Common Core State Standards for Mathematical Content :
Measurement and Data
MACC.2.MD.9Generate 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 whole number units.
MACC.2.MD.10Draw 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. / Comments:
Students had experience with line plots in the Unit of Study 9–Length and Customary Measurement.

See common performance task link below.
Unpacking the Standards for this Unit: Within this unit students collect information about categorical and numerical data and construct organized displays of data in formats such as tally charts, line plots, picture graphs and bar graphs which may go up to four categories. Beginning in second grade, students are expected togenerate the data and construct the graphical representation.Critical thinking skills are developed as students make decisions about how information should be collected and organized. As students are constructing their data displays, they should be aware of how the data display is interpreted by persons not involved in the actual development of the graph. Students should be familiar with both horizontal and vertical graph orientations.Students will encounter problems which require data interpretation and be asked to make inferences from the data. Classroom discussion on analyzing data and solving problems with data is vital.Students whose experiences are limited to interpreting pre-prepared data displays (e.g. workbook pages) are missing key components of this standard. At this time, students will utilize a one to one correspondence with data representations (e.g. one item within a category is represented by one tally mark, one picture, or one unit on a bar graph).

Common Performance Task with Rubric for this Unit:InThe Zoo, students organize data by creating a tally chart and bar graph then answer questions about the data.

Future learning: Collecting, classifying, representing data, and interpreting data supports students in understanding information about the world around them. Students should understand the graphed data involves asking and answering questions and the representation has an impacton the reader. Students utilize categorical and numerical data within informational text and throughout science standards.
