Representations of Linear Relationships

5 min

Teacher Prep
Setup
Students in groups of 2. 1 minute of quiet think time, followed by partner and whole-class discussions.

Narrative

In this activity, students estimate the volume of different containers by reasoning about characteristics of their shape. 

Launch

Display the image for all to see and ask students to estimate which container holds the most liquid and which holds the least. Tell students to give a signal when they have an estimate and can explain their reasoning. 

Student Task

Which container holds the most liquid? The least?

<p>phot of 3 glasses. glass A, short, wide cylinder. glass b, tall, thin cylinder. glass c, hour glass shape, medium height.</p>

 

Sample Response

Answers vary.

Activity Synthesis (Teacher Notes)

Ask students to indicate which container they think holds the most liquid and record the responses for all to see. Invite a few students to share their reasoning and the characteristics of the container that were important in making their decision. If possible, record these characteristics on the images themselves during the discussion.

It turns out that B holds the least and A and C hold the same amount of liquid. If possible, consider showing the answer video.

Liquid is poured from one container to the other to see which one holds more liquid.
