Students will find angle sums using a baseball diamond diagram.

Use this lesson to help your students learn about partitioning shapes into parts with equal areas. Students will explain rectangular shape area in fractions of a whole.

Your students will have a blast thinking about polygons and making these paintings inspired by Wassily Kandinsky!

With this activity, students will identify shapes, build 3-D shapes, and practice describing shapes with a partner.

Shape up your students' understanding of geometrical attributes with this hands-on math lesson. Students will gain a better understanding of how to describe a shape by the number of edges and vertices it has, rather than by its name.

Give your students a head start on 3D shapes with this lesson that has them use their observational skills to identify what differentiates the shapes.

Teach your students about the attributes that make each shape unique. Use this as a stand alone lesson or as a pre-lesson for Are You Connected to Me?

In this lesson, your students will use hands-on visuals to learn about fractions! Your students will love using manipulatives to practice placing fractions on a number line.

In this lesson, your students will play "I Spy" to identify 3-D shapes. They will use language to describe the shapes and be able to compare them easily.

Explore 3-D shapes with your students and help them identify and talk about the relevant attributes of three-dimensional shapes, all while using real-world examples! Use this as a stand-alone lesson or alongside the Shape Models lesson.

Geometry is a core of mathematics in the early years. Help students recognize and draw shapes given specific attributes such as the number of corners and sides. This lesson can be a stand-alone activity of paired with 2-D Shapes!

Teach your students about symmetry with real life objects! Have them draw lines of symmetry for various shapes, food items, and objects.

Bring on the polygons! Your students will build their understanding of polygons and sort shapes into categories based on their attributes in this lesson.

Students will learn out how to partition a rectangle using by partitioning shapes with rows and columns.

Students will solve area problems by multiplying side lengths for rectangular shapes in real world contexts.

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.

It’s pizza time! Students will be introduced to the concept of partitioning shapes to create fractions that demonstrate halves, fourths, and eighths. This lesson is the first of two lessons that address second grade fraction concepts.

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.

Slice those pieces and mix it up! In this lesson that follows “Slice It Up! Part One,” students will begin recognizing different ways to create equal shares in whole shapes, creating a fraction poster by the end of the lesson.

Symmetry is everywhere, but it's often hard to notice. This lesson explores a few ways to identify it. By folding and making mirror images for different shapes, students will discover a new world of symmetrical figures.

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.

Explore the beauty of Navajo rug weaving with this lesson that integrates indigenous culture, math and art. Students will learn and practice symmetry and create a design in the tradition of the Navajo rug pattern called “Two Grey Hills”.

What's in the bag? This fun math lesson involves using defining attributes as clues to draw conclusions. Young learners will have a great time making guesses about different objects and creating their own shape riddles.

Get your students discussing the attributes of polygons by having them categorize statements as always, sometimes, or never true. Use this lesson independently or alongside Characteristics of Polygons.

Where's the other half? In this lesson, young mathematicians learn the relationship between halves and symmetry through a fun scavenger hunt. Your students will have a blast figuring out what makes a shape symmetrical.

How are quadrilaterals connected? In this lesson, your students will learn about the relationship between quadrilaterals by drawing, defining, and labeling different ones.

A hands-on approach makes geometry fun! Use this lesson to teach your students about the basics of perimeter with geoboards.

Root, stem, flower, leaf! In this hands-on science lesson, your students will create their own plants to help them identify and remember the parts of a plant.

In this lesson, your students will collect and organize data to make a beautiful bar graph! They will also practice analyzing the graphs with the information they have.

Provide students with an opportunity to identify the wholes that are correctly divided into halves, thirds, and fourths (equal shares). Use this activity alone as a support lesson or alongside Cookie Fractions Fun.
