Help your students learn the standard measures of length and foster critical thinking with this engaging lesson. Use alongside The Smaller They Come or as a stand-alone activity.

Advance your students from relative measurements to learning about standardized units with this lesson that teaches them about inches and feet by using common classroom objects.

In this lesson, your students will measure the lengths of items and then make a line plot to show the measurement data. They will get hands-on by measuring and surveying the class.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

This support lesson provides students the opportunity to use two different tools to measure the length of familiar objects while introducing content specific vocabulary words. Use alone or alongside the lesson How Big is the Playground?

Students will learn to convert metric units by applying concepts in word problems. Exercises and worksheets incorporate length (meters), and optional practice offers more instructions on mass (grams) and volume (liters).

Allow your students to explore the pros and cons of different strategies used to find the area of rectangles. Use this as a stand alone lesson or as a pre-lesson for the Multiplication and Area in the Community Garden lesson.

Students will use the inverse relationship between multiplication and division to complete an area formula in a real-world situation. Use this lesson on its own or as support for the lesson The Case of the Missing Rectangle Side.

Teach your students to find the perimeter of polygons using real world examples. They will make polygon pictures using tangrams and practice finding the perimeters of the polygons in their masterpieces.

Help your students use rulers in the classroom with this lesson! Encourage them to measure items around them using centimeters to understand shapes and sizes.

Get your students comfortable discussing their math thinking in converting centimeters to meters. This lesson may be used on its own or as support to the lesson Converting Metric Measurements to Decimals & Fractions.

Look out! Measurement is all around us! In this lesson, students will learn about measuring tools and how to use them. Students will work cooperatively on a fun measurement hunt, exploring and applying concepts of measurement using inches.

Word problems can be overwhelming to students, but if they have a tool to help them, they can handle it! Use this as a stand alone lesson or alongside Stepping Through Addition and Subtraction Word Problems.
