IM 6.3.3 Lesson: Measuring with Different-Sized Units
Your teacher will show you two rods. Does it take more green rods or blue rods lined up end to end to measure the width of a piece of printer paper?
STATION 1: Each large cube is 1 cubic inch. Count how many cubic inches completely pack the box without gaps. Each small cube is 1 cubic centimeter. Each rod is composed of 10 cubic centimeters. Count how many cubic centimeters completely fill the box.
STATION 2: Your teacher showed you a length. Use the meter stick to measure the length to the nearest meter. Use a ruler to measure the length to the nearest foot.
STATION 3: Watch the video.
Count how many times you can fill the quart bottle from the gallon jug.
Count how many times you can fill the liter bottle from the gallon jug.
STATION 4: Use the applet to record the weights of different objects in different units.
Record their weights in ounces, pounds, grams, and kilograms.
STATION 5: Count how many level teaspoons of salt it takes to fill the graduated cylinder to 20 milliliters, 40 milliliters, and 50 milliliters. Pour the salt back into the original container.
Which is larger, a cubic inch or a cubic centimeter? Did more cubic inches or cubic centimeters fit in the cardboard box? Why?
Did it take more feet or meters to measure the indicated length? Why?
Which is bigger, a quart or a liter? Explain your reasoning.
Use the data from Station 4 to put the units of weight and mass in order from smallest to largest. Explain your reasoning.
About how many teaspoons of salt would it take to fill the graduated cylinder to 100 milliliters?
If you poured 15 teaspoons of salt into an empty graduated cylinder, about how many milliliters would it fill?
How many milliliters per teaspoon are there?
How many teaspoons per milliliter are there?
People in the medical field use metric measurements when working with medicine. For example, a doctor might prescribe medication in 10 mg tablets.[br][br]Brainstorm a list of reasons why healthcare workers would do this. Organize your thinking so it can be followed by others.
IM 6.3.3 Practice: Measuring with Different-Sized Units
Decide if each is a measurement of length, area, volume, or weight (or mass).
How many centimeters across a handprint
How many square inches of paper needed to wrap a box
How many gallons of water in a fish tank
How many pounds in a bag of potatoes
How many feet across a swimming pool
How many ounces in a bag of grapes
How many liters in a punch bowl
How many square feet of grass in a lawn
Clare says, “This classroom is 11 meters long. A meter is longer than a yard, so if I measure the length of this classroom in yards, I will get less than 11 yards.” Do you agree with Clare? Explain your reasoning.
Tyler’s height is 57 inches. What could be his height in centimeters?
A large soup pot holds 20 quarts. What could be its volume in liters?
Clare wants to mail a package that weighs [math]4\frac{1}{2}[/math] pounds. What could this weight be in kilograms?
Noah bought 15 baseball cards for $9.00. Assuming each baseball card costs the same amount, answer the following questions.
At this rate, how much will 30 baseball cards cost? Explain your reasoning.
At this rate, how much will 12 baseball cards cost? Explain your reasoning.
Do you think this information would be better represented using a table or a double number line? Explain your reasoning.
Jada traveled 135 miles in 3 hours. Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.
How far did Jada travel in 1 hour?
How far did Andre travel in 1 hour?
Who traveled faster? Explain your reasoning.
