SFUSD Mathematics Core Curriculum, Grade 3, Unit 3.11: Volume and Weight, 2014–2015

Unit Overview

Big Idea

Volume and mass are attributes that can be estimated and measured using appropriate standard units.

Unit Objectives

● Students will be able to measure and estimate liquid volumes and masses of objects using the standards units of grams, kilograms and liters. ● Students will be able to solve one-step word problems involving masses or volumes that are in the same units using addition, subtraction,

multiplication, or division.

Unit Description

In this unit, students will continue to build their understanding of measurement expanding it to include the topics of Volume and Mass. Students will find exact and estimated measurements using liters when measuring volume, and grams/kilograms when measuring weight. Students will use all four mathematical operations applying their understanding of volume and weight to solve one-step word problems.

CCSS-M Content Standards

3.MD.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 unit, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

Progression of Mathematical Ideas

Prior Supporting Mathematics Current Essential Mathematics Future Mathematics

In second grade, students recognized the need for standard units of measure (centimeter and inch) and used rulers and other measurement tools with the understanding that linear measure involves an iteration of units. They recognized that the smaller the unit, the more iterations they will need to cover a given length.

Third grade is students’ first exposure to the measurement of mass and volume. Students will measure and estimate volume and mass, using grams, kilograms, and liters. They will also use multiplication, division, addition, and subtraction to solve one-step problems.

In fourth grade, students will understand the relative sizes of measurement units within one system specifically: grams, kilograms, and liters. Within this system of measurement, students will gain practice in converting units from grams to kilograms and kilograms to grams

Unit Design All SFUSD Mathematics Core Curriculum Units are developed with a combination of rich tasks and lessons series. The tasks are both formative and summative assessments of student learning. The tasks are designed to address four central questions: Entry Task: What do you already know? Apprentice Task: What sense are you making of what you are learning? Expert Task: How can you apply what you have learned so far to a new situation? Milestone Task: Did you learn what was expected of you from this unit?

What Do You Know About Weight and Volume?

What will students do?

Mathematics Objectives and Standards Framing Student Experience

Math Objectives: ● Assess students’ prior knowledge in concepts of weight(how much an

object weighs and volume (how much liquid a container holds). ● Assess student knowledge of choosing appropriate tools to measure

weight and volume. CCSS-M Standards Addressed: 3.MD.2 Potential Misconceptions

● An object weighs the same if it is the same size. ● Objects are only measured linearly (1-D), just length. ● One tool is used for all measurements. ● Students might confuse the word ‘volume’ with ‘sound volume’.

Launch: ● Remind students they learned how to measure length of objects in

second grade. ● Brainstorm when they might have have measured how heavy

something is or how much liquid a container holds in real life. ● Remind students they already have some knowledge about weight and

volume from life experiences. During:

● Student complete the Entry Task individually. Closure/Extension:

● After teacher reviews entry task to assess what students already know, teacher may choose to review it as a whole class.

Weighing and Measuring

What will students do?

Mathematics Objectives and Standards Framing Student Experience

Math Objectives: ● Students will solve one-step measurement problems using

addition, subtraction, multiplication, and division. ● Students will measure weight in grams and volume in

liters. CCSS-M Standards Addressed: 3.MD.2 Potential Misconceptions

● The terms and abbreviations, g and L, may be confusing. ● Students may confuse the operations they should use for

each problem and forget the labels that distinguish weight and volume.

Launch: Remind students they have been practicing measuring weight and volume using grams and liters. They have also been using these measurements to solve one-step measurement problems. Tell them they will be solving some real life problems involving reading the measurement of weight on a scale and solving problems with that information. During: Students will solve the problems and explain their thinking individually. During this time, the teacher will walk around and note strategies students are using to solve their problems. Closure/Extension: Have a class discussion where students can share the strategies or misconceptions they had. Other students can explain their own strategies to clear up misconceptions. The teacher can also showcase some students’ work to model the grade-level math that was expected. This might be a good time to include a math talk based on some of the misconceptions collected during the observations and class discussion.
