Objective

By the end of this lesson, you will be able to understand the muscular system and how it relates to the movement of hands, as well as learn some basic sign language.

Materials and Prep

• Chart paper or whiteboard
• Markers or chalk
• Printed hand anatomy diagrams
• Printed sign language alphabet chart

No prior knowledge or preparation is required for this lesson.

Activities

1. Start by discussing the muscular system and its importance in our body. Explain how muscles help us move and control our hands.

2. Show the printed hand anatomy diagrams and point out the different muscles in the hand. Discuss their functions and how they work together.

3. Engage the student in a hands-on activity where they can feel and observe their own hand muscles. Have them make different hand movements and ask them to identify the muscles responsible for each movement.

4. Introduce the concept of sign language and its importance in communication for people with hearing impairments. Show the printed sign language alphabet chart and explain how each letter is represented using hand movements.

5. Practice signing the alphabet together. Start with a few letters and gradually add more as the student becomes comfortable.

6. Encourage the student to create their own sign language messages using the alphabet they have learned. They can write short sentences or spell out words using the sign language alphabet.

Third Grade Talking Points

• "Muscles are special tissues in our body that help us move our hands and other body parts."
• "There are different muscles in our hands that work together to help us grip objects, write, and perform various tasks."
• "Sign language is a way of communicating using hand movements, especially for people who cannot hear."
• "The sign language alphabet consists of different hand shapes that represent each letter of the English alphabet."
• "By learning sign language, we can communicate with people who are deaf or hard of hearing."
• "Let's practice signing the alphabet together. Start with the letter 'A' and we'll work our way through the entire alphabet."
• "Now that we know the sign language alphabet, we can create our own messages using these hand movements. Let's try spelling out our names or simple words."
