Lesson/Unit Plan

Overview:

In this lesson, students learn why non-standard measures can be useful even when measurements must be quite precise. This Cyberchase activity is motivated by a video segment in which the CyberSquad must lower Digit, the Cyberbird, from the ceiling to remove an audiotape from the voice box of a statue of Hacker.

Content Standard(s):

Mathematics
MA2019 (2019)
Grade: 4

22. Use the four operations to solve measurement word problems with distance, intervals of time, liquid volume, mass of objects, and money.

a. Solve measurement problems involving simple fractions or decimals.

b. Solve measurement problems that require expressing measurements given in a larger unit in terms of a smaller unit.

c. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

Evidence Of Student Attainment:

Students:
When given multistep word problems involving units of measure will,

Represent and solve world problems involving whole number measurements and require expressing measurements when given a larger unit in terms of a smaller unit.
Example: Given a picture frame which is 2 feet long and 8 inches wide, express the perimeter of the picture frame in inches.
Represent and solve word problems involving two measurements given in the same units, one a whole number measurement and the other a non-whole number measurement.

Example: Given a picture frame with dimensions 1/2 ft and 8 in, express the perimeter of the picture frame in inches.

Use visual representations to illustrate a measurement scale.

Note: Quantities are limited to expectations in grade 4 standards and operations will not include division of fractions or decimals.

Teacher Vocabulary:

Operations
Distance
Intervals of time
Liquid volume
Mass
Number line diagram
Measurement scale

Knowledge:

Students know:

Relative sizes of units within one system of measurement.
Strategies to solve word problems involving the four operations.
Measurement units in the same system are multiplicatively related.

Skills:

Students are able to:

Solve measurement word problems
Involving distance, intervals of time, liquid volume, mass, and money.
Involving measurement conversion of larger units to a smaller unit.
Involving simple fractions or decimals.
Using diagrams to represent measurement quantities and solutions.

Note: Quantities and operations are limited to grade 4 standard expectations.

Understanding:

Students understand that:

Relationships among units within a system of measurement are multiplicative comparisons.
The size of the unit of measurement and the number of units are inversely related.
Addition and subtraction of measurements require measurements in the same unit and that the common unit is maintained in the answer.

Diverse Learning Needs:

Essential Skills:

Learning Objectives:
M.4.22.1: Define distance, time, elapsed time, volume, mass.
M.4.22.2: Determine elapsed time to the day with calendars and to the hour with a clock.
M.4.22.3: Express liquid volumes and masses of objects using standard units of grams, kilograms, and liters.
M.4.22.4: Use addition, subtraction, multiplication and division to solve one- and two-step word problems.
M.4.22.5: Recognize key terms to solve word problems.
M.4.22.6: Recall basic facts for addition, subtraction, multiplication, and division.
M.4.22.7: Identify monetary equivalents.
Examples: four quarters equal one dollar, five one-dollar bills equals five dollars.

Prior Knowledge Skills:

Define liquid volume, mass, grams, kilograms, and liters.
Recognize how the standard units of measure compare to one another.
Identify key terms for word problems.
Examples: Difference, altogether, in all, between.
Express the length of an object as a whole number of length units by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
Recall basic addition, subtraction, multiplication, and division facts.
Describe measurable attributes of objects such as length or weight. Describe several measurable attributes of a single object.
Compare equivalent units of time using hours and minutes.
Examples: 60 minutes = one hour, 30 minutes = one half of an hour.
Recognize key vocabulary and/or phrases associated with time.
Examples: Quarter 'til = 15 minutes before; half past the hour = 30 minutes after the hour M. 3.16.3: Compare the lengths of time to complete everyday activities.
Examples: Brushing your teeth = about 2 minutes; riding the bus = about 20 minutes.

Alabama Alternate Achievement Standards

AAS Standard:
M.AAS.4.22 Using vocalization, sign language, augmentative communication, or assistive technology, tell time on a digital and analog clock (to the hour, half-hour, quarter hour).
M.AAS.4.22a Measure mass, volume, or lengths of an object when given a measurement tool.
M.AAS.4.22b Using vocalization, sign language, augmentative communication, or assistive technology, identify and determine the value of penny, nickel, dime, and quarter.
