Which Three Go Together?
10 min
Narrative
This Warm-up prompts students to carefully analyze and compare features of four geometric figures. In making comparisons, students have a reason to use language precisely (MP6). The activity also enables the teacher to hear the terminology students know and how they talk about characteristics of figures.
In the discussion, it is important to talk about things the writer had to pay attention to when they designed this activity.
Launch
- Groups of 2
- Display the image.
- “Pick 3 that go together. Be ready to share why they go together.”
- 1 minute: quiet think time
Teacher Instructions
- “Discuss your thinking with your partner.”
- 2–3 minutes: partner discussion
- Share and record responses.
Student Task
Which 3 go together?
Sample Response
Sample responses:
A, B, and C go together because:
- They are solid figures.
A, B, and D go together because:
- They have an area or volume with a value of 36.
A, C, and D go together because:
- They all have the side or edge lengths labeled.
B, C, and D go together because:
- Each of them has one side or edge length of 2 units.
Activity Synthesis (Teacher Notes)
- “What did you look for when deciding which 3 go together, or when finding a reason why 3 go together?” (the number of sides, the types of angles or corners, the way they were oriented, how many shapes there were in each)
- Record and display responses for all to see.
- “What did the writer of this activity have to pay attention to when they designed this activity?” (The writer looked for those same things but needed to make sure that all groups had at least 3 features in common. Also, each item needs to miss a feature that the other three items have.)
Standards
- 5.MD.3·Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
- 5.MD.C.3·Recognize volume as an attribute of solid figures and understand concepts of volume measurement.
