• Summarise key concepts learned during the lesson with a class discussion

Extension Activity:

• For early finishers, provide an extension activity where they design their own prism shapes and calculate their surface area and volume

Homework:

• Homework activity suggestion: Create a real-world scenario where students need to calculate the surface area and volume of a prism they encounter in their daily lives

Standards Addressed:

• 10.G-GMD.A.2: Understand and apply the formulas for the surface area and volume of prisms.

To further engage students in understanding prisms, you can consider the following hands-on activities:

1. Prism Manipulation: Provide students with physical prisms made of different materials (e.g., plastic, wood) and have them manipulate the prisms to identify their bases and faces. This tactile experience can help solidify their understanding of the 3-dimensional nature of prisms.

2. Building Prisms: Have students use building blocks or clay to construct their own prisms. This activity allows students to physically create prisms, helping them visualize the concept of 2 congruent bases in parallel planes.

3. Prism Exploration Stations: Set up different stations around the classroom with various prism models, where students can rotate and examine the prisms from different angles. This activity encourages students to explore prisms in-depth and understand their properties.

4. Prism Surface Area Challenge: Provide students with different prisms and challenge them to calculate the surface area of each prism. This interactive challenge can make surface area calculations more engaging and competitive.

5. Virtual Reality Prism Exploration: If available, use virtual reality technology to allow students to immerse themselves in a virtual space filled with different prisms. This modern approach can enhance students' understanding by providing a unique and interactive experience.

These hands-on activities can help students visualize and comprehend the concepts related to prisms more effectively.

To set up the hands-on activities for engaging students in understanding prisms, you may need the following resources and materials:

1. Prism Manipulation:

   • Physical prism models made of different materials (plastic, wood, etc.)

   • Labels to identify bases and faces of the prisms

2. Building Prisms:

   • Building blocks or clay for students to construct their own prisms

   • Rulers or measuring tools to ensure accuracy in creating prisms

3. Prism Exploration Stations:

   • Various prism models (different shapes and sizes) for students to explore

   • Rotating platforms for easy examination of prisms from different angles

4. Prism Surface Area Challenge:

   • Different prism models for students to calculate surface area

   • Worksheets or grids for students to record their calculations

5. Virtual Reality Prism Exploration:

   • Virtual reality headsets or devices with prism exploration software

   • Guidance on how to use the virtual reality technology effectively

Additionally, you may need access to a classroom or space where these activities can be set up comfortably. It's also beneficial to have supporting materials such as worksheets, answer keys, and any necessary instructional guides to facilitate the hands-on activities smoothly.

Incorporating group work or collaboration opportunities within these hands-on activities can enhance student engagement and promote cooperative learning. Here are some suggestions on how to implement group work in the prism-related activities:

1. Group Prism Manipulation:

   • Divide students into small groups and provide each group with different prism models.

   • Encourage students to work together to identify the bases and faces of the prisms, discussing their observations and reasoning with their group members.

   • Have groups present their findings to the class, promoting discussion and peer learning.

2. Collaborative Prism Building:

   • Assign groups of students to work together to build a specific type of prism using building blocks or clay.

   • Encourage collaboration and communication within the group to ensure the prism is constructed accurately.

   • Have groups showcase their prisms to the class and explain the process they followed to create them.

3. Station Rotation for Prism Exploration:

   • Arrange stations with different prism models around the classroom.

   • Have groups rotate through the stations, encouraging students to discuss and compare their observations of the prisms at each station.

   • Provide group tasks or questions related to the properties of the prisms at each station to promote collaboration.

4. Group Prism Surface Area Challenge:

   • Form small groups and present each group with a set of prism models to calculate surface area.

   • Encourage students to work together to solve the surface area calculations, discussing their strategies and reasoning with their group members.

   • Hold a friendly competition among groups to see who can correctly calculate the surface area of the prisms in the shortest time.

By incorporating group work and collaboration opportunities, students can benefit from peer interaction, shared problem-solving, and diverse perspectives, leading to a more enriching learning experience in the exploration of prisms.

Incorporating technology or online tools can enhance group work and collaboration in prism-related activities. Here are some suggestions for using technology to facilitate group work:

1. Online Collaboration Platforms:

   • Utilize platforms like Google Workspace (Google Docs, Google Slides) or Microsoft Teams for group work on identifying prisms, calculating surface area, and determining volume. Students can collaborate in real-time on shared documents or presentations.

2. Virtual Whiteboard Tools:

   • Platforms such as Jamboard or AWW App allow students to work together on a virtual whiteboard to sketch out prism structures, label bases and faces, and solve surface area and volume calculations collaboratively.

3. 3D Modeling Software:

   • Platforms like Tinkercad or SketchUp enable students to create and manipulate 3D models of prisms virtually. Groups can design their own prism shapes, explore different dimensions, and calculate surface area and volume within the software.

4. Online Quiz and Polling Tools:

   • Use tools like Kahoot or Poll Everywhere to create interactive quizzes or polls related to prisms. Groups can compete in quizzes to test their understanding of prism properties and calculations.

5. Virtual Reality (VR) Prism Exploration:

   • If available, VR platforms like CoSpaces Edu or Nearpod VR can provide an immersive experience for students to explore virtual prisms together. Groups can navigate through 3D environments to identify different prism shapes and properties.

6. Video Conferencing Tools:

   • Platforms such as Zoom or Microsoft Teams can facilitate group discussions and presentations on prism-related tasks. Students can collaborate virtually, share their screens, and engage in discussions with their group members.

By integrating technology into group work activities, students can collaborate effectively, engage in interactive learning experiences, and strengthen their understanding of prisms through digital tools and resources.
