Section A: Practice Problems Metric Measurement

Section Summary

Details

In this section, we measured the length of objects using different length units. We learned that the centimeter is a standard length unit and we measured lengths in centimeters using base-ten blocks, rulers, and meter sticks. We learned that rulers represent length units using tick marks to show a length from zero.

We also learned that a meter is a length unit in the metric system that is longer than a centimeter. When measuring longer lengths, it is easier to use a meter stick. A meter has the same length as 100 centimeters.

Problem 1 (Pre-Unit)

How many connecting cubes long is the rectangle?

Problem 2 (Pre-Unit)

Jada has 16 red counters. She has 7 fewer yellow counters than red counters. How many yellow counters does Jada have? Show your reasoning with words, pictures, or numbers.

Problem 3 (Pre-Unit)

1. Which rectangle is the longest?

2. Which rectangle is the shortest?

Problem 4 (Pre-Unit)

Find the value of each expression.

Problem 5 (Lesson 1)

How many centimeters long is each rectangle?

Problem 6 (Lesson 2)

Here is a rectangle.

1. How many centimeters wide is the rectangle?

2. How many centimeters tall is the rectangle?

Problem 7 (Lesson 3)

How many centimeters long is each side of the triangle? Label each side.

Problem 8 (Lesson 4)

Here is a rectangle.

1. Estimate how many centimeters long the rectangle is.

cm

2. Measure the rectangle and record the measurement.

cm

3. How does your estimate compare to the actual length?

Problem 9 (Lesson 5)

A python is a snake that grows up to 9 meters in length.

1. Is the python longer or shorter than the animals you measured?

2. Is the python longer or shorter than the alligator and adult cobra together?

Problem 10 (Lesson 6)

Andre’s snake is 85 centimeters long. His lizard is 28 centimeters long. How many centimeters longer is Andre’s snake than his lizard? Show your thinking.

Problem 11 (Exploration)

Here are 2 rectangles.

1. Which rectangle do you think is longest?

2. Measure with a centimeter ruler to check your guess.

Problem 12 (Exploration)

1. Look for objects in the classroom that are about 1 centimeter long. Measure them and see how close they are to 1 centimeter.

2. Look for objects in the classroom that are about 1 meter long. Measure them and see how close they are to 1 meter.
