# What Is a Sphere? How to Recognize Spheres in Everyday Objects - Lesson Plan

• Do you want to make learning about 3D shapes fun and engaging for your young students? With this lesson plan, you will explore one of the most common and exciting 3D shapes: the sphere. Your students will learn what a sphere is, how to recognize it, and why it is important to know about it.

They will also watch a video, play some games, and do activities to help them practice finding spheres in everyday objects. By the end of this lesson, they will be able to identify and name spheres with confidence and enthusiasm.

## Why This Lesson Plan Is Great for Kids

• This lesson plan is designed to appeal to the curiosity and creativity of young learners. It uses various methods, such as visual, auditory, kinesthetic, and social, to engage different learning styles and preferences.
• This lesson plan is aligned with the Common Core State Standards for Mathematics for kindergarten and first grade. It covers the following standards:
• G.A.2: Correctly name shapes regardless of their orientations or overall size.
• G.B.4: Analyze and compare two- and three-dimensional shapes in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners"), and other attributes (e.g., having sides of equal length).
• G.A.1: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
• This lesson plan is also suitable for pre-k students who are ready to learn about 3D shapes. It introduces the concept of spheres in a simple and accessible way, using familiar objects and examples.

Duration: 20 - 30 minutes

Objectives: By the end of this lesson, students will be able to:

• Define what a sphere is
• Identify spheres in different sizes, colors, orientations, and materials
• Compare spheres with other 3D shapes
• Name some real-life objects that are shaped like spheres
• Demonstrate understanding of the properties of spheres, such as rolling in any direction and having no edges or vertices

This lesson plan is flexible and adaptable to different classroom settings and situations. You can adjust the duration, difficulty, and number of activities according to your students' needs and interests. You can also use different materials and resources that are available to you.

• ### Previous knowledge

Before attending this lesson, students should know:

• The names of some basic 2D shapes, such as circle, square, triangle, rectangle
• The difference between 2D and 3D shapes
• How to sort objects by shape

### Materials

For this lesson, you will need:

• A computer or a projector to show the video (Video link: https://youtu.be/vAbwr8Hfct8)
• A speaker or headphones to play the sound
• A whiteboard or a chart paper to write on
• A marker or chalk to write with
• Some objects that are shaped like spheres, such as balls, oranges, apples, balloons, marbles, etc.
• Some objects that are not shaped like spheres, such as cubes, cones, cylinders, pyramids, etc.
• Some paper plates or cardboard circles
• Some scissors
• Some glue or tape
• Some string or yarn

• ### Introduce the lesson

To introduce the lesson, you can do the following:

• Write the word "sphere" on the board or the chart paper. Ask the students if they know what it means. Explain that a sphere is a 3D shape that looks like a ball. It is round and smooth all over. It has no flat faces, no corners, and no edges.
• Show the students some examples of spheres that you have prepared. Ask them to name them and describe them. For example: "This is a ball. It is red and bouncy." "This is an orange. It is orange and juicy." "This is a balloon. It is blue and inflated."
• Ask the students if they can think of other objects shaped like spheres. Please encourage them to look around the classroom or think of things they have seen or used before. Write their answers on the board or the chart paper.
• Tell the students that today, they will learn more about spheres and how to recognize them in everyday objects. They will watch a video, play some games, and do activities to help them practice finding and naming spheres.
• ### Warm-up

To warm up the students, you can do the following:

• Play a game of "I Spy" with spheres. Choose an object shaped like a sphere and say: "I spy with my little eye something round and smooth." Give the students some clues, such as the object's color, size, or location. Let them guess what it is. Repeat with different objects until everyone has a chance to participate.
• Play a game of "Simon Says" with spheres. Give the students some commands that involve spheres, such as: "Simon says touch a sphere." "Simon says roll a sphere." "Simon says bounce a sphere." "Simon says, hold a sphere over your head." Ensure to include some commands unrelated to spheres, such as: "Simon says clap your hands." "Simon says jump up and down." If you say "Simon says" before the command, the students should follow it. If you don't say "Simon says" before the command, the students should not follow it. If they do, they are out of the game. The last student standing wins.
• ### Introducing the concept

To introduce the concept of spheres, you can do the following:

• Show the students the video from mathskills4kids.com. The video is about 3 minutes long, explaining what a sphere is and how to recognize it. It also shows examples of spheres and asks questions to check the students' understanding. You can pause the video at any time to ask or answer questions, clarify doubts, or emphasize important points.
• After watching the video, review the main ideas with the students. Ask them to recall what they learned from the video. Write their responses on the board or the chart paper. For example: "A sphere is a 3D shape that looks like a ball." "A sphere can roll in any direction." "A sphere has no flat faces, no corners, and no edges."
• Ask the students to compare spheres with other 3D shapes they know, such as cubes, cones, cylinders, or pyramids. Ask them to identify the similarities and differences between them. For example: "A cube and a sphere are both 3D shapes, but a cube has six flat faces and a sphere has none." "A cylinder and a sphere are smooth all over, but a cylinder has two flat faces, and a sphere has none." "A pyramid and a sphere are both 3D shapes, but a pyramid has flat faces, corners, and edges, and a sphere has none."
• ### Activities and games

To reinforce the concept of spheres, you can do the following activities and games with the students:

• Have a scavenger hunt for spheres. Divide the students into small groups and give each group a basket or a bag. Ask them to look around the classroom or outside for objects shaped like spheres. They should collect as many as possible and put them in their basket or bag. Set a time limit for the hunt, such as 10 minutes. When the time is up, ask each group to show their findings to the class. Count how many spheres each group has collected and declare the winner.
• Have a sorting activity for spheres. Give each student a paper plate or cardboard circle and some glue or tape. Ask them to cut out pictures of objects shaped like spheres from magazines, newspapers, catalogs, or flyers. They should glue or tape them onto their paper plate or cardboard circle. They can also draw their own pictures of spheres if they want. Ask them to share their work with the class when they are done. Compare and contrast their choices and discuss why they are spheres.
• Have a craft activity for spheres. Give each student some string or yarn and some scissors. Ask them to cut out different lengths of string or yarn and tie them together at one end. They should then wrap them around their fingers or hands to form a ball shape. They can use different colors of string or yarn if they want. When done, ask them to tie off the other end of their string or yarn ball and cut off any excess. They can then decorate their balls with stickers, glitter, beads, or anything else they like. Ask them to share their creations with the class when they are done.
• ### Group Sharing

After the activities and games, you can invite the students to share their findings and experiences with the rest of the class. You can ask them questions like:

• What did you learn about spheres today?
• How did you recognize spheres in everyday objects?
• What was your favorite activity or game?
• How did you work with your partner or group?

Encourage the students to use the vocabulary they learned, such as sphere, solid, roll, edge, and vertex. Praise their efforts and achievements, and provide feedback as needed.

• ### Conclusion

To conclude the lesson, you can review the main points and concepts with the students. You can use a chart or a poster to summarize the characteristics and examples of spheres. You can also ask the students to recall some interesting facts they learned about spheres, such as how they can roll in any direction and have no edges or vertices. You can also show them some more examples of spheres in real life, such as planets, bubbles, or balls.

### ✨ Assessment

To assess the students' understanding of the lesson, you can use different methods, such as:

• Observing their participation and performance during the activities and games
• Checking their worksheets or projects
• Asking them oral or written questions
• Giving them a quiz or a test

You can use a rubric or a checklist to evaluate their knowledge and skills. You can also provide feedback and suggestions for improvement.
