Unit 7

3rd Grade

Lesson 10 of 12

Objective

Understand liquid volume as an attribute of objects that is measured in liters and milliliters. Develop benchmarks for 1 liter and 1 milliliter.

Common Core Standards

Core Standards

  • 3.MD.A.2 — Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem. Excludes multiplicative comparison problems (problems involving notions of "times as much"; Excludes compound units such as cm³ and finding the geometric volume of a container.

Foundational Standards

  • 2.MD.A.1

Criteria for Success

  1. Understand liquid volume as an attribute of a liquid related to how much space it takes up.
  2. Compare the volume of liquid in different containers. 
  3. Develop benchmarks for 1 liter and 1 milliliter. 
  4. Determine whether amounts of liquid have a volume of about 1 liter, about 1 milliliter, or more or less than either benchmark.

Tips for Teachers

  • For Anchor Task 2 as well as the Problem Set, students will need a medicine/water dropper to approximate the volume of 1 milliliter and a 1-liter bottle to approximate the volume of 1 liter. If you do not have enough of these objects, use anything in their place that has a volume close to those measurements.
  • For the Problem Set, you’ll need a classroom set of about 12 containers for students to compare to the benchmark volumes of 1 milliliter and 1 liter. You could be very strategic and set out particular items that you’d like students to measure that are close to each benchmark volume (e.g., spoons, thimbles, bottle caps, etc. for 1 milliliter as well as large plastic cups or bottles, pitchers, Tupperware containers, etc., for 1 liter).
  • For the Extra Practice Problems, students will need the same objects for the 1 milliliter and 1 liter benchmarks as are used for the Problem Set. If you use these as homework and don’t want students to bring these objects home, you could also assign the task of “Capacity Ordering" from 3.MD.2 - About the Math, Learning Targets, and Rigor from the Howard County Public School System, which asks students to find five containers and list their capacities in order, which wouldn’t require students to bring home benchmark measures. 

Lesson Materials

  • 1-quart container (1 per small group) — There are other options to use in place of this material. You can also just use one for the teacher if materials are limited. See Anchor Task 1 Notes for more information.
  • 1-pint container (1 per small group) — There are other options to use in place of this material. You can also just use one for the teacher if materials are limited. See Anchor Task 1 Notes for more information.
  • Half-liter container (1 per small group) — There are other options to use in place of this material. You can also just use one for the teacher if materials are limited. See Anchor Task 1 Notes for more information.
  • Quarter teaspoon (1 per small group) — There are other options to use in place of this material. You can also just use one for the teacher if materials are limited. See Anchor Task 1 Notes for more information.
  • Water (About 3 liters per small group)
  • Medicine or water dropper (1 per small group) — Students can use any container with a capacity of about 1 milliliter. These are also needed for the Problem Set and Extra Practice Problems. See Tips for Teachers for more information.
  • 1-liter plastic bottle (1 per small group) — Students can use any container with a capacity of about 1 liter. These are also needed for the Problem Set and Extra Practice Problems. See Tips for Teachers for more information.
  • Various containers (About 12 per class) — These are needed for the Problem Set. See note in Tips for Teachers for more information.

Problem 2

The milliliter and liter are standard units used to measure liquid volume. A dropper full of water has a volume of about 1 milliliter (mL). A medium-sized bottle of soda has a volume of a liter (1 L). 1,000 milliliters is the same volume as 1 liter. Decide whether the water in the following containers has a volume of about 1 milliliter, about 1 liter, or neither. 

a.   Container A

b.   Container B

c.   Container C

d.   Container D

Problem Set

15-20 minutes

Discussion of Problem Set

  • What unit would you prefer to use to measure the volume of each container in #2 and #4?
  • How are the units milliliter and liter similar? How are they different? 
  • What new math vocabulary did we use today to communicate precisely about how much a container can hold?

Target Task

5-10 minutes

Additional Practice

The Extra Practice Problems can be used as additional practice for homework, during an intervention block, etc. Daily Word Problems and Fluency Activities are aligned to the content of the unit but not necessarily to the lesson objective, therefore feel free to use them anytime during your school day.

Word Problems and Fluency Activities

Word Problems and Fluency Activities

Help students strengthen their application and fluency skills with daily word problem practice and content-aligned fluency activities.
