Mathematics Alignment Lesson Grade 5 Quarter 2 Day 48 Common Core State Standard(s) 5.G.3 Understand that attributes belonging to a category of two-dimensional figures can also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. 5.G.4 Classify two-dimensional figures in a hierarchy based on properties. Alignment Lesson Create a Hierarchy Diagram (Day 2 of 2) 1. Discuss Journal Prompt question from yesterday’s homework. 2. Give each student pair a piece of chart paper on which to transfer their hierarchy diagram from yesterday. Give students 10-15 minutes to transfer their diagrams. 3. As students are working, circulate and choose 4-5 pairs of students to verbally share their hierarchy diagrams with the class later in the lesson. Try to choose as many different variations as possible. 4. Post all hierarchy diagrams around the room and invite students to take a quick gallery walk. Standards for Mathematical Practice Standard 3 - Construct viable arguments and critique the reasoning of others. Standard 6 - Attend to precision. Materials Needed: Blackline Masters, “Create a Hierarchy Diagram Reflection Tool” Chart paper and markers Assessment Informal: Hierarchy diagrams created by pairs Assess individual student responses on “Create a Hierarchy Diagram Reflection Tool.” 5. Invite each of the pairs of students you strategically selected to share their hierarchy diagrams. As students share, engage the class in Math Talk, incorporating some of the following questions as appropriate: Questions for Student Pairs Presenting: What did you find most challenging about creating your hierarchy diagram? What figures did your group have the most trouble organizing into the hierarchy diagram? Why? Questions for Other Members of the Class: How did this group classify and organize their twodimensional figures? How does the organization of the figures in this hierarchy diagram compare to the one you and your partner created? Are there any figures for which you don’t agree with their location in the hierarchy diagram? Note: Be sure to address misconceptions and misplaced figures by allowing students to talk to each other and share their own experiences and thinking. Continue to focus student discussion back to the definitions, and encourage students to draw examples and non-examples to help address the misconceptions. 6. If time permits, invite other pairs of students to present their hierarchy diagrams and engage in similar discussion as above. 7. Instruct students to complete Blackline Master, “Create a Hierarchy Diagram Reflection Tool,” and collect student responses for assessment purposes. Homework Blackline Master- “Examples and NonExamples of Two-Dimensional Figures” Wake County Public School System, 2012 8. Students should complete Blackline Master, “Examples and Non-Examples of Two-Dimensional Figures,” for homework.

What did you find most challenging about creating your hierarchy diagram? What figures did you and your partner have the most trouble organizing into the hierarchy diagram? Why? How does knowing the definitions and properties of twodimensional figures help you classify and organize them in a hierarchy diagram?
