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.

Create a Hierarchy Diagram Reflection Tool
Directions: Think about how you and your partner sorted, classified, and organized the
figures in your hierarchy diagram and answer the questions below.
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?
