Showing Results for of a rectangle using square units

Your students will become junior math detectives as they hunt down the missing side of a rectangle by applying the area formula for rectangles. The only clues they have are the rectangle's area and the measure of one side.

The Case of the Missing Rectangle Side

Young mathematicians will enjoy demonstrating their skills with this lesson on finding area. It addresses the concepts of length, width, and square units. 

What's My Area?

You need the length and the width to find the area of a rectangle or square, but what if one piece of information is missing? Use this lesson alongside *What&#39;s My Area?* or on its own.

Finding Area: What Information Do I Need?

Students will become more familiar with common metric measurements by matching everyday objects with the metric mass and volume units they would use to measure them. 

Estimating Measurements of Mass and Volume Using Metric Units

In this lesson, your students will calculate and illustrate area for rectangles using area models, where one side length includes a fraction.

Illustrating Areas in Fractional Units

Let your students learn how to find the area of rectangular objects by doing hands-on activities. Your students will love finding the area of various rectangular objects around the classroom!

Finding the Area of a Rectangle

Help your students get creative as they apply multiplication skills to find the area of a community garden of their own design! In this lesson, students will practice finding the area of a rectangle within a real-world context.

Multiplication and Area in the Community Garden

Use this vocabulary-focused lesson to teach your students about area. It can stand alone or be used as a pre-lesson for *Finding the Area of a Rectangle*.

All About Area

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.   

What Is the Area of Your Classroom?

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.

Area Arrangements

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

Building Squares

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.

Using Tape Models to Compare Like Fractions

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.*

Which Unit of Measurement?

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. 


Calculating Volume Using the Formula (L x W x H)

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

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. 

Information Gaps and Finding the Area

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).

Converting Metric Measurement in Word Problems

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.

Adding Mixed Numbers Using the Decomposition Strategy

Teach your students to subtract mixed numbers with like denominators using the strategy of decomposition. This strategy helps students to manipulate and break down numbers to help them solve tricky subtraction problems. 

Subtracting Mixed Numbers Using the Decomposition Strategy

Let's divide! In this hands-on lesson, your students will get in on some fraction action when they pair up to create and compare fraction models with the same denominator.

Fraction Action: Rectangles

Teach your students to create equivalent fractions by multiplying by different fraction forms of 1 whole like 2/2 or 4/4. This lesson also includes drafts of area models.

Equivalent Fractions Using Area Models

Imagery is one of the most important tools in a narrative writer's arsenal. In this lesson, students will will learn to craft vivid scenes by selecting powerful verbs and adjectives, as well as to critique descriptive writing using the same criteria.

Using Adjectives and Verbs to Make Writing Come to Life

How do your students measure up when it comes to metrics? This lesson introduces young mathematicians to grams and kilograms and allows them to explore the units' real world applications.

Gram I Am

Introduce your students to area and teach them to use the formula **Area = Length x Width** within the context of real world problems.

Multiplication and Area

Teach your students fair shares with this hands-on resource. Using this lesson plan, your class will create, label, and illustrate sums for fair shares using a folded paper model.

A Fair Share of Fractions

Use this lesson to help your ELs use information from text features to better understand the text. It can be a stand-alone lesson or a support lesson for the Text Features: Reading that Makes Sense lesson.

Using Text Features for Comprehension

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.

Perfect Perimeter

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.

Polygon Perimeters with Tantalizing Tangrams!

In this lesson, students will find the perimeter of figures using cheese crackers. Next, they'll design a floor plan for their cheese cracker dream house, to help them practice and retain the formula for finding perimeter.

Finding Perimeter

Why walk when you can mosey? In this lesson, students will learn how to use synonyms to express shades of meaning in their writing. Introduce the topic with a book, then brainstorm descriptive options for overused words.
