Unpacking the Standard: 2.MD.D.10
Student Friendly Learning Target: 2.MD.D.10
Visual Representation of Learning Target: 2.MD.D.10
This standard focuses on the students’ ability to create bar graphs and pictographs from data, and then use these graphical representations to solve problems. This skill builds on previous standards involving organizing data and creating plot lines. It relates to addition and subtraction work emphasized in grade 2, and it prepares students for more in-depth data analysis and visualization in future grades.
Understanding the Standard:
- Provide a variety of opportunities for students to categorize objects or other data sets in the world around them. Such activities might include sorting shoes, personal attributes (e.g., hair color, eye color, boys and girls), ways they get to school, favorite color. Once the sets have been determined, guiding students to create a display of the information in a bar or picture graph is expected.
- Students need to be able to compare as few as two sets of data and up to four sets of data and then use another set to make a generalization. Upon mastery, students can then use numerical references of the data to compare using addition and subtraction.
- Give students sets of data in addition to just having children collect data, and have students create graphs to represent the data. Giving them multiple opportunities to create graphs from given data will enable students to understand how to create visual graphs.
Questions to Focus Instruction:
- Are students able to answer questions related to the information in the graph and compare sets of data for greater understanding?
- Can students create bar graphs that accurately represent data?
- Can students extract data from bar graphs?
- Can students use data in bar graphs to solve one-step addition and subtraction problems?
Mastery at this level includes the ability to separate a set of objects into many categories and then communicate the reasoning for each grouping. Go to 1.MD.C.4
to see previous skills in this progression.
At Grade Level:
Students can create their own bar graphs and pictographs to represent data. Students can solve one-step addition and subtraction problems using bar graphs and pictographs.
Students will create a scaled picture graph of collected data. Students will also solve one- and two-step problems that pertain to the graph and data. Go to 3.MD.B.3
