Do you need extra help for EL students? Try the Exploring CapacityPre-lesson.

Students will be able to compare the capacity of different containers based on the container's attributes.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

(10 minutes)
  • Gather the students together and show them your cup of water, tea, or coffee.
  • Ask the students to think-pair-share what the maximum amount of liquid your cup can hold is called.
  • Allow a few students to share their ideas with the rest of the class.
  • Explain to the students that the maximum amount of liquid your cup can hold is called its Capacity.
  • Tell the students that today they will be comparing the capacity of different containers based on the container's Attributes.
(15 minutes)
  • Put the students in small groups of 5–6 students. Pass out the plastic coverings and ask students to tape/drape the coverings over their tables.
  • Give each small group 3–5 different containers including pudding containers, applesauce containers, rectangular tupperware containers, yogurt containers, and tin cans. Each small group needs the same containers.
  • Provide each group with a scoop of some kind, such as a measuring cup (1/2 cup or 1 cup). Make sure each small group has the same size scoop.
  • Place the bucket of water on each table.
  • Explain to the students that in their small groups, they will first predict how many scoops they think each container will hold (e.g. The tin can will hold ____Scoops of water.) They should record this information in their maths journals.
  • Model completing a PredictionTo support students in understanding the task.
(5 minutes)
  • Ask a small group to model the process and orally share their prediction with the rest of the class.
  • Give students five minutes to make their predictions. Rotate around the classroom and support students as needed.
(10 minutes)
  • Instruct students to figure out how many scoops of water each object holds and record their findings in their maths journals.
  • Provide sentence frames to support students in writing down their findings, such as:
    • My prediction was right/wrong because the ____(object) held ____(number) scoops. I thought the ____(object) would hold ____Scoops.

Enrichment:Advanced students may want to measure the capacity of more objects or oddly shaped objects.

Support:Struggling students may benefit from working with a partner.

(10 minutes)
  • Have students indicate which container has the greatest capacity and which container has the least capacity.
  • Ask students to answer these questions in their journal: Which container has the greatest capacity? How do you know?
(5 minutes)
  • Allow a few students to share out their findings.
  • Hold a discussion about how the attributes of the objects might have caused them to predict the capacity would be less or more than its actual capacity.
