Finding the area of a rectangle is a key measurement skill to know. In this lesson, your students will enjoy practicing this skill by determining the area of their classroom.

Students will get hands-on practice by building shapes with pipe cleaners in this lesson all about the defining attributes of rectangles. Use as a stand alone lesson or with the Shapes for Kindergarten lesson plan.

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.

In this hands on lesson, students create squares with different fraction pieces while building their knowledge of adding fractions with different denominators.

Teach your students to compare fractions using symbols ( >, < = ) in three easy steps. Using this lesson plan, your class will compare like fractions using tape diagrams.

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.

The world is their measuring stick! In this lesson, students will practice measuring objects using the world around them for units of measurement.

Get your students explaining estimations and measurements of liquid volumes and masses of objects! Use this lesson independently or alongside Estimating Measurements of Mass and Volume Using Metric Units.

Learning about shapes isn't "square" with this lesson! Students will learn what makes up a shape and learn to draw them themselves which will turn into a fun hands-on clay molding activity.

Notetaking doesn’t just have to fit in a square! In this lesson, students will use different shapes to help them take notes and remember what they should be paying attention for as they read.

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.

Students will begin to calculate volume of different rectangular prisms using base ten cubes and then transition to using the formula V = L x W x H. Students will then practice using the legendary fifth grade activity, Cootie Catchers.

Use this lesson plan to teach your students to illustrate division as multiplication using number lines.

Facilitate rich math conversations with this lesson on finding the missing information in problems related to the area of rectangles and squares. It may be taught by itself or used as support to the lesson Finding Area: Furnishing A Room.

Use this lesson to reinforce using sentence level context clues to decode challenging words in a nonfiction text. This can be used as a stand alone activity or a support the Using Context Clues to Understand Word Meanings lesson.

This lesson helps students identify even and odd numbers, which sets the foundation for learning about division, prime numbers, and even square roots. Use this hands on lesson alongside Odd One Out!

Students will get hands-on experience manipulating shapes in this preschool-friendly activity. With the help of shape blocks and worksheets, little learners will get the hang of squares, triangles and rectangles in no time.

2D shapes are all around us! In this lesson students will explore the properties of four different shapes—triangles, circles, rectangles, and squares! They will learn that they can find these shapes anywhere in the world around us.

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).

Make the number work for you! Use this lesson to teach your students to add mixed numbers with like denominators using the strategy of decomposition.
