Learning Objectives
By the end of the session, Grade 4 students will:
- Identify Practical Needs: Recognize and brainstorm everyday items that can be enhanced or created using 3D design.
- Design Functional Objects: Utilize TinkerCad to design objects with practical uses, such as desk organizers, bookmarks with clips, or custom keychains.
- Apply Advanced Tools: Use alignment, grouping, and other advanced TinkerCad tools to create precise and functional designs.
- Enhance Creativity and Problem-Solving: Develop creative solutions to everyday problems through design.
- Prepare for 3D Printing: Ensure designs are optimized for printing by checking dimensions, overhangs, and wall thickness.

Structure and Lesson Plan (Total Time: 60 minutes)
1. Introduction and Inspiration (10 minutes)
-
Greet the Students:
- “Good morning, everyone! Today, we’re going to design objects that you can use in your daily life using TinkerCad.”
-
Introduce the Theme:
- “We’ll focus on creating functional items like desk organizers, bookmarks with clips, and custom keychains. These are things that can help you stay organized and make your daily tasks easier.”
-
Show Visual Aids:
-
Display images of various functional objects created in TinkerCad.
-
“Look at these awesome designs! These objects not only look cool but also serve practical purposes.”
-
-
Discussion:
- “Think about the things you use every day. What could be improved or what new item would make your life easier?”
2. Brainstorming Session (15 minutes)
-
Pair Formation:
- “Pair up with a partner and discuss ideas for a functional object you’d like to design.”
-
Distribute Materials:
- Hand out paper and pencils to each pair.
-
Guided Brainstorming:
-
Prompts:
- “What is something you use every day that you wish could be better?”
- “Is there an object you need but haven’t found the perfect version of?”
- “How can you solve a problem you face using a functional object?”
-
Sketching Ideas:
- “Draw a simple sketch of your idea. Think about its purpose and how it will help you.”
-
-
Teacher and Assistant Support:
-
Circulate the room to assist pairs with brainstorming and sketching.
-
Encourage creativity and practicality in their ideas.
-
3. Transition to Digital Design (5 minutes)
-
Explain the Next Step:
- “Now that you have your ideas on paper, it’s time to bring them to life in TinkerCad!”
-
Set Up Devices:
- Ensure each pair has their device ready with TinkerCad open to a new design workspace.
-
Reminders:
- “Remember to work together and refer back to your sketches as you design.”
4. Hands-On Designing in TinkerCad (25 minutes)
-
Guidelines and Expectations:
- “Use the tools and shapes in TinkerCad to start building your functional object. Focus on making it both useful and visually appealing.”
-
Design Techniques:
-
Alignment and Grouping:
- “Use alignment tools to position your shapes accurately. Group shapes together to form a single object.”
-
Combining Shapes:
- “Combine different shapes to create the parts of your object. For example, use cylinders for holes or connectors.”
-
Customizing Designs:
- “Add details to personalize your object. Maybe add your name to a keychain or decorative elements to a desk organizer.”
-
-
Examples:
-
Desk Organizer:
- Base: Rectangular box.
- Compartments: Smaller boxes for holding pens and pencils.
- Holes: Centered perfectly for cables.
-
Bookmark with Clip:
- Base: Thin rectangular shape.
- Clip: Small cylinder or hook shape attached precisely to one end.
-
Custom Keychain:
- Base: Small shape (circle, heart, etc.).
- Attachment: Hole centered perfectly for a keyring.
-
-
Teacher and Assistant Support:
-
Move around the room to provide individual assistance.
-
Help students troubleshoot alignment issues and grouping mistakes.
-
Encourage students to think about the functionality and aesthetics of their designs.
-
-
Encourage Creativity:
- “Feel free to experiment with different shapes and designs. Your object should be something that you find useful and cool!”
-
Reminders:
-
“Save your work frequently.”
-
“Check your design for any overhangs or areas that might need supports if printed.”
-
5. Sharing and Feedback (5 minutes)
-
Invite Students to Share:
- “Would anyone like to share their design with the class? Show us what you’ve created and explain how it works.”
-
Provide Positive Feedback:
-
“Your desk organizer is so organized and looks great!”
-
“I love how you added a clip to your bookmark—it makes it super functional!”
-
6. Conclusion and Preview of Next Session (5 minutes)
-
Summarize the Session:
- “Today, you designed functional objects that can help you in your daily life. You used advanced tools in TinkerCad to make your designs precise and practical.”
-
Preview Next Session:
- “In our next class, we’ll prepare your designs for 3D printing. We’ll learn how to check your models for printability and get them ready to be brought to life!”
-
Closing Encouragement:
- “Great job today! Keep thinking about how you can improve your designs and get ready to see them printed soon.”
Common Challenges and Solutions:
- Misaligned Shapes:
- Solution: Guide students to use the alignment tool to center shapes accurately before grouping.
- Grouping Errors:
- Solution: Ensure only the intended shapes are selected for grouping. Remind students to verify their selections.
- Overcomplicating Designs:
- Solution: Encourage students to keep designs simple and functional, especially when creating objects with practical uses.
Glossary
- Alignment: Positioning shapes accurately relative to each other to ensure proper functionality and aesthetics.
- Grouping: Combining multiple shapes into a single, unified model to simplify manipulation and design.
- Functional Object: An item designed to serve a practical purpose in daily life.
- Overhang: Parts of a model that extend outward without support, which may require additional design considerations for printing.
- Wall Thickness: The thickness of the outer walls of a 3D printed object, affecting its strength and durability.
- Shape Generator: A tool in TinkerCad that creates unique and complex shapes to enhance designs.
- Community Shape Libraries: Collections of shapes created and shared by the TinkerCad user community, available for use in designs.
- 3D Modeling: The process of creating a three-dimensional representation of an object using software.
