Unit Title: Place Value and Multi-Digit Arithmetic

Lesson: 11 Measure and Estimate Volume

Approx. time:

60 minutes

CCSS-M Standards:3.NBT.13.MD2. Measure and estimate liquid volume of objects using standard unit of liters.

A. Focus and CoherenceStudents will know…

the relative size of standard units of liquid

Students will be able to…

measure and estimate liquid volumes using standard metric units (liters)

Student prior knowledge: Volume is the space a solid, liquid, or gas takes up. We measure the volume of liquids in liters and

milliters. Liters are units of measurement in the metric system.

Which math concepts will this lesson lead to? Students will be able to estimate liquid volume in

everyday items using 1 liter as a reference point. Students will be able to add, subtract, multiply, or

divide to solve one step word problems using liters as the unit.

B. Evidence of Math PracticesWhat will students produce when they are making sense, persevering, attending to precision and/or modeling, in relation to the focus of the lesson?

I know that liter measure liquid volume. I know that liter is not weight. I know that ____ is greater than 1 liter. I know that ____ is less than 1 liter. I know to use 1 liter as a reference point from which to

compare.

Essential Question(s) When and why do we use liters in real-life situations? What objects do we measure in liters? How much is 1 liter?

Formative Assessments

Anticipated Student Preconceptions/Misconceptions Confusing volume as weight 1 liter comes in various shapes Liters are bigger than milliliters (1000ml = 1 L)

Materials/Resources Different size liquid soda bottles labeled A,B,C, ( 1 liter, less than 1 liter, greater than 1 liter) Different shape liquid bottles that equals 1 liter Correcting pencil or pen

C. Rigor: fluency, deep understanding, application and dual intensityWhat are the learning experiences that provide for rigor? What are the learning experiences that provide for evidence of the Math Practices? (Detailed Lesson Plan)

Warm UpPass out the attached warm-up activity sheets to student pairs (Worksheet A). Read the instruction together. Students work in partner. We will be discussing your answer choices at the end of the lesson.

Lesson

Teacher tells students, “In this lesson, you will learn how to estimate liquid volume in liters by using 1 liter bottles as a reference object.”

Teacher reviews: “Volume is the space a solid liquid, or gas takes up. A balloon is an example of gas. A bag of rice is an example of a solid. A soda bottle is an example of liquid volume. We measure the volume of liquids in liters and milliliters. A liter can be measured with a water/soda bottle. A milliliter is measured with a dropper. A common mistake is confusing volume with weight or mass. For example, a liter of soda weighs 2.2 pounds and a liter of motor oil weighs 1.92 pounds.”

Present the various sized labeled liquid bottles in incorrect order of volume sizes and have students correct teacher’s arrangement. Ask students for reasoning. Teacher re-labels the bottles as less than 1 liter, 1 liter, greater than 1 liter. Teacher says, “We will be using the 1 liter bottle as a reference point to compare or estimate the volume of other containers.

Refer to teacher sheet 1, “Which object do you think will be filled up with 2 liters? (Refer back to the real 1 liter bottle and explain how the picture on the paper is scaled smaller but represent this real bottle.) Which object do you think will be filled up with 10 liters? Which object do you think will be filled up with 50 liters?” (Key: 2 Liter is the orange juice. 10 liter is the water cooler. 50 liter is the barrel.)

Pass out worksheet B to students. “Look at the number line. Point to where the 1 liter is. (Refer to the 1 liter soda bottle from model so students will connect realia to drawings/labels on sheet). Teacher may use attached clip art or bring in containers for activity. Teacher holds up various objects or pictures such as coffee pot, spoon, mug, water cooler, swimming pool, bath tub. Students will locate the point on the number line where the object would be located and label with object name. Students discuss responses in groups. Display one group’s paper for class, and have class agree/disagree. (Key: Less than 1 liter: spoon, mug, coffee pot; 1 liter: soda bottle; Greater than 1 liter: water cooler, bath tub, swimming pool)

ClosureRefer back to the warm-up sheet, “Would anyone like to change their previous answer and why?” Students revise

with correcting pencil or pen.

Key: (1 Liter items are Smart Water and motor oil. Clarify 1 liter can come in various shape containers. Less than 1 liter is the juice box. Greater than 1 liter is the 2 Liters Windex. Play dough is a solid, therefore not measured in liter )

Suggested Homework/Independent PracticeWorksheet C

Find three things in your home whose liquid volume can be measured in liters. Find one container that is 1 liter, one that is greater than 1 liter, and one that is less than 1 liter. Draw these objects on your paper in volume size order and label. What type of liquid was in each container?
