Showing Results for rectangles

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

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.


Finding All of the Flat Shapes

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.

Area Strategies

Start a dialogue around area models! In this lesson, encourage students to ask questions as they multiply using area models. Use this lesson on its own or as support to the lesson Area Models and Multiplication.

Area with Multiplying and Adding

Area models are building blocks to more complicated multiplication and division. Use this lesson to refresh students on the relationship between multiplication and area to prepare them to use the area models strategy with larger numbers.

Area Models and Multiplication

In this lesson, your students will become familiar with shapes by identifying them in real life. Your students will love identifying how many sides shapes have by drawing and counting them!

Know Your Shapes!

What's the difference.... between two numbers? Play this fun game to get students talking and practicing subtraction. Use this scaffolded EL lesson plan alone or alongside **Subtraction Card Sharks.**

What's the Difference?

Practice calculating perimeter with the placement of carnival-themed games with given rectangular dimensions. Your students will use grid paper to determine the location of all the games they choose to make the perfect carnival.

Perimeter of Play

“Gong Xi Fa Cai, Hong Bao Na Lai!” This means "Happy New Year, Give me my red envelope!" Students will count coins and write the value all while learning about the Chinese New Year tradition of handing out red envelopes filled with money. 


Counting Money for Red Envelopes: A Chinese New Year Tradition

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

Help students visually represent multiplication with mixed numbers and whole numbers. Use this lesson as a standalone lesson, or as support for the lesson Multiplication of Mixed Numbers with Area Models.

Area Models and Mixed Numbers

Sorting takes on a new challenge for students in this activity which engages their critical thinking skills. As students determine defining attributes, they’ll figure out what makes a shape a shape!

Shape Sort

Get your students synthesizing various subtraction strategies as they work with a partner to solve word problems. This lesson can be used alone or with the lesson plan **Show Me the Money! Two-Digit Subtraction.**

Subtraction Strategies

It’s magic! In this lesson, students will “magically” move shapes together to form new shapes. Clay and toothpicks equal hands-on fun! Tangram challenges are provided for those students who need that little extra challenge.

Magical Movement

What is the likelihood that a polar bear will walk into the classroom? Students will consider this and other events using the concept of probability and the terms: Impossible, unlikely, likely, and certain.

Exploring Probability: What Are The Chances?

Students will explore geometric shapes by creating a painting of a trapezoid.

Trapezoids Are Special

Get your students excited to learn about fractions with this hands on lesson. Working in groups will help students learn from each other and share ideas.

Parts of a Set: Fractions

Mae Jemison was the first African American female astronaut to enter space. Use the Get to Know Mae Jemison lesson plan to learn more about this famous scientist. Children will then read and write about her, and create their own paper rocket.

Get to Know Mae Jemison

Students will get to explore three-digit numbers through base-ten blocks and written form. Students will get plenty of practice identifying the place values of a number both individually and with the class.

All About Three-Digit Numbers

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!

Give students plenty of practice adding to 20 with this fun game! Use this scaffolded EL Lesson alone or for more addition practice before teaching the **Do Math with M&Ms** lesson.

Addition Number Grab

Use this lesson to introduce the concepts of capacity and volume with young learners. This hands on lesson can be used as a scaffolded pre-lesson to Capacity Comparison. 

Exploring Capacity

Help students color-code their way to multiplying fractions! Students will learn how to multiply fractions using area models. Use this lesson on its own or use it as support to the lesson Area Models and Multiplying Fractions.

Visually Multiplying Fractions

Help your students visually represent equivalent fractions! Use this lesson on its own or or as support to the Show Me Equivalent Fractions! lesson.

Compare Visuals for Equal Fractions

Help students use two strategies that will help them figure out which three-digit number is greater than, less than, or equal to another three-digit number. Use on its own or with Let's Compare! Place Value Disks & Three-Digit Numbers.

Comparing Values

Fractions are in everyday life! This lesson reviews how to solve word problems involving fractions using tape diagrams. The problems include addition, subtraction, and multiplication of fractions.

Fractions and Word Problems
