Unit 3 Overview
Examples of Hands-On Manipulatives in Geometry Topics
In the third unit of the mini-course, participants will discover how hands-on manipulatives can be used to enhance comprehension of various geometry topics, including surface area and volume of three-dimensional figures, different types of transformations, and more. The unit ends with participants working in small groups to create a lesson plan for a given geometry topic that incorporates the use of hands-on manipulatives to support mathematical understanding to demonstrate their learning.
Lesson 1: Volume and Surface Area
Lesson 2: Triangle Theorems
Lesson 3: Geometric Transformations
Lesson 4: Design Geometry Lesson Plan
Lesson 1: Volume and Surface Area

Task 1 - Directions: Watch the following videos that demonstrate how to use unit cubes to find the volume of rectangular prisms and nets to find the surface area of various figures.
Analyze the videos and describe how the use of hands-on manipulatives enhances student learning. Specifically think about how hands-on manipulatives provide advantages over just memorizing the formulas for volume and surface area. Explain how you may use the information learned from these videos to improve your existing lesson plans (200-300 words). Post your response to the discussion board. Reply to at least one classmate.
Task 2 - Directions: If there are additional hands-on manipulatives that you use in your classroom to support the learning of volume and surface area, please add it to the Slide 6 of the Jamboard using a Sticky Note. This shared list of hands-on manipulatives will continue to grow throughout the mini-course as members keep contributing to the shared space. Refer to the Jamboard at the end of each lesson to get inspiration for new idea of how you can utilize hands-on manipulative in your mathematics classroom.
Lesson 2: Triangle Theorems

Task 1 - Directions: Watch the following videos that demonstrate how to use hands-on manipulatives to prove several triangle theorems.
Analyze the videos and describe how the use of hands-on manipulatives enhances student learning. Explain how you may use the information learned from these videos to improve your existing lesson plans (200-300 words). Post your response to the discussion board. Reply to at least one classmate.
Task 2 - Directions: If there are additional hands-on manipulatives that you use in your classroom to support the learning of simplifying expressions, please add it to the Slide 7 of the Jamboard using a Sticky Note. This shared list of hands-on manipulatives will continue to grow throughout the mini-course as members keep contributing to the shared space. Refer to the Jamboard at the end of each lesson to get inspiration for new idea of how you can utilize hands-on manipulative in your mathematics classroom.
Lesson 3: Geometric Transformations

Task 1 - Directions: Watch the following videos that demonstrate how to use hands-on manipulatives to complete geometric rotations on a coordinate grid.
Analyze the videos and describe how the use of hands-on manipulatives enhances student learning. Specifically the key differences between the two methods and the advantages of the method you prefer. Explain how you may use the information learned from these videos to improve your existing lesson plans (200-300 words). Post your response to the discussion board. Reply to at least one classmate.
Task 2 - Directions: If there are additional hands-on manipulatives that you use in your classroom to support the learning of solving equations, please add it to the Slide 8 of the Jamboard using a Sticky Note. This shared list of hands-on manipulatives will continue to grow throughout the mini-course as members keep contributing to the shared space. Refer to the Jamboard at the end of each lesson to get inspiration for new idea of how you can utilize hands-on manipulative in your mathematics classroom.
Lesson 4: Design Geometry Lesson Plan
Task 1 - Directions: Participants will work in small groups to design a geometry lesson plan centered around using hands-on manipulatives to promote mathematical reasoning and greater levels of understanding. Each groups will be assigned one of the following topics for their geometry lesson plan:
- Volume of a Cylinder
- Volume of a Cone
- Surface Area of a Cylinder
- Triangle Exterior Sum Theorem
- Triangle Inequality Theorem
- Translating Figures
- Reflecting Figures over the x-axis and y-axis
Lesson Plan Template - Each lesson plan must include objectives, instructional plan/activities, hands-on manipulatives used, a rationale of how the use hands-on manipulatives was beneficial to student learning.
Task 2 - Directions: If there are additional hands-on manipulatives that you use in your classroom to support the learning of any geometry topic, please add it to the Slide 9 of the Jamboard using a Sticky Note. This shared list of hands-on manipulatives will continue to grow throughout the mini-course as members keep contributing to the shared space. Refer to the Jamboard at the end of each lesson to get inspiration for new idea of how you can utilize hands-on manipulative in your mathematics classroom.
