Fully charge the tablets and robots.
Install the Wonder Workshop Blockly app on each tablet.
Have recycled materials easily accessible for students to work with.
Have students review and discuss this lesson’s coding concepts in groups. This can include:
Explain to students that when coding with Blockly, we use block commands to sequence from the top down in the proper order. Example: We put our socks on first and then shoes -- not the other way around.
Example: We put our socks on first and then shoes, not the other way around.
Students should be far enough along to understand that loops are a repeated set of instructions that can be placed inside a Repeat Forever or Repeat block. Ask, “What tasks in the real world require multiple loops?”
Sample response: A relay race where you have to run through an obstacle course and dump water in a pail. Different sets of instructions that are repeated in the relay task could be: running through obstacles, pouring water in a bucket, passing a water bottle to the next person.
Have students discuss the various event handlers in the When block (such as When Top Button 1 or When Clap).
Say, “Today you will design a new accessory for Dash to solve a classroom problem. It’s time for you all to become designers!”
Use the 2-5 Design Thinking Presentation to introduce the iterative design thinking process to the class. Say, “Design thinking has been used to develop all kinds of inventions we use each day, like smartphones, cars, board games and video games. We can use design thinking to improve conditions in our classroom.”
Understand: “It’s important to understand how those around us feel about things. When we understand how users are feeling and the problems they face, we can learn about problems that we all might share.”
Define: “Designers must be able to identify a problem or a need that they will attempt to solve. For example, our classroom floor gets messy after craft activities. That’s a problem.”
Ideate: “The word ‘idea’ is the root word of the word ‘ideate.’ That’s because when we ideate, we come up with ways to solve a problem. Brainstorming allows us to come up with all kinds of ideas and then work together to decide on which ideas we’d like to try first. For example, we could design a program and accessory for Dash to sweep up the floor.”
Plan: “Once designers select the best solution, they make a plan. They draw a diagram of their design and figure out what materials they will need. For example: You will probably need legos to build a sweeper for Dash to clean the floor.”
Build: “You can begin by building a rough version of your group’s design. This rough version is called a prototype. We do this in the same way that we would create a rough draft when we write. It’s okay to make mistakes, because that’s how we learn to make improvements. During construction, we frequently stop to test and retest our prototype. Then we ask ourselves, 'How can we improve it?' Each time we make a change in our design, we retest our prototype. It does not need to be perfect. It just needs to work well enough to test out the features of your group’s design.”
Test: “Once we’ve built a Dash accessory that sweeps the floor, we must test it out. Does it work? Does it solve the problem? If not, can we tweak it in some way to make it work? Is the problem in the accessory or the program we’ve written? It’s okay to make mistakes. The important thing is to learn from our mistakes and make changes, when needed. We can also get feedback from our peers and from the people who will be using the accessory. We can use that feedback to improve our designs!”
What are the different stages of the design thinking process?
Why is it important to have different stages?
What does the word “ideate” mean, and why is it an important part of the design process?
Which stage is most important, and why?
Ask, “What kinds of problems do we run into in the classroom?”
Sample responses: “Trash on the floor, the classroom getting too noisy, papers being left out, the lights being left on.”
Work with the class to brainstorm the problems that bother them in the classroom. List the problems on the whiteboard or poster paper.
Do not judge ideas as good or bad at this time.
Once you've gotten all ideas written down, read them aloud.
Discuss what accessories students could design for Dash that could help solve some of the identified problems.
Could Dash have a bulldozer to sweep the floor?
Could Dash have a hand to help turn off the lights?
Discuss how students could program Dash to demonstrate the accessory.
Could you use a loop to have Dash dance and entertain the students?
Could you use a When block/Event Handler?
What is the problem that you would like to solve?
What will you build as an accessory for Dash to solve that problem?
How will you use the blocks in Blockly to solve your problem?
How could you include the When or Repeat block in your program?
Which parameters will need to change when programming Dash? (Sample response: “distance, speed, time, events.”)
Will you have Dash say something or make a sound?
Divide the class into small groups (ideally 2–3 students per robot) and distribute a Design Thinking Workbook to each group.
Have groups use the Design Thinking Workbook to guide them through the design process. Make sure students get their work approved before they advance to the next design stage.
Share the Evaluation Rubric with the class so that students are aware of your learning and performance expectations.
Have student groups use the Design Thinking Workbook to:
Record the list of classroom problems that was created by the class.
Discuss and add any other classroom problems to the list.
Narrow this list down to a top classroom problem.
Explain the selected problem in detail.
Remind students that they may need to compromise.
Have student groups use the Design Thinking Workbook to:
Brainstorm and record possible solutions for their selected problem.
Select their top solution.
Explain the selected solution in detail with words and diagrams.
Have students use the Design Thinking Workbook to:
Establish team roles such as:
Lead Programmer: Holds the tablet and integrates group member ideas to create the program in Blockly.
Documentarian: Records, writes, and/or draws all group results, thoughts, and progress. Illustrates group designs and ideas.
Lead Builder: Collects the materials needed to build the accessory. The lead builder oversees the building and testing of the prototype.
Draft a detailed sketch of their accessory idea for Dash.
Each student in the group should contribute to the sketch by using different-colored pencils/markers/crayons.
By giving each student a different-colored pencil to draw, the teacher can tell that all students have participated in the planning of their group’s accessory.
Have each group share their sketch with you.
Have students make any needed adjustments to their original plan based on your feedback.
Have students use the Design Thinking Workbook to:
Make a list of the recycled materials they will need to build a prototype of their design.
Gather the necessary materials.
Build the prototype.
Have each group share their prototype with you.
Have them making any needed adjustments based on your feedback.
Have students use the Design Thinking Workbook to:
Plan a program for Dash that will help demonstrate their accessory design.
Use the Blockly app to develop their program.
Record the results of their code and prototype.
Make any improvements based on their test.
The program should contain criteria that you’ve established based on students’ coding abilities. For example, the criteria could include: sequences, loops, and/or event handlers.
Remind students of the criteria (e.g., “Don’t forget to include a When block and a Repeat block. Think about which portion of the program Dash must repeat more than once”).
Have students create a presentation that includes the following elements:
Images of the invented accessory for Dash.
Screenshot of the final program created in the Blockly app.
Video of Dash using the accessory.
Have students organize their presentation using posters or digital platforms such as Seesaw, iMovie, or Google Slides.
Have student groups take turns presenting their projects to the class.
Encourage students to give each other feedback on their designs, programs, and/or presentations. Possible questions/feedback includes:
“How did you (build that accessory and what did you use)?”
“I like how you (added lights and sounds to your program).”
“What if you (recorded a sound for your program)?”
Did your design work as planned? Why or why not?
How could this design be scaled up for use in the real world?
Do you think other classes could use your accessory/program?
What was the hardest part of the design process?
If you had time to redesign, what would you change?
Use our Evaluation Rubric to review students’ work and presentations.
[Optional] Share your students’ work with the world using @wonderworkshop and #dashanddot!
Make sure that all groups have drafted a plan for their program that includes your established criteria before giving them a tablet to code.
Check in with groups as you circle the room. Ask guided questions such as:
What is your group’s classroom problem?
How are you going to solve the problem?
What challenges have you faced?
How did you overcome them?
Create heterogeneous ability groupings so that those who are stronger can help those in need.
Use a talking object for the brainstorming stage. When the object is passed to the student, he or she may share an idea. This avoids students talking over one another.
While some students are challenged by the basic requirements of this lesson, incorporate more complex programming requirements for students who have demonstrated mastery. This can include:
Adding Dot to the program when using When blocks/ Event Handlers.
Developing another accessory that solves a different problem.
Using the Wonder app to program Dash.
For struggling students, scale down the project by:
Having them use the Path app to program Dash.
Minimizing the programming requirements (e.g., requiring them to use only movement and lights).
Students can:
Take a picture and share their designs with each other to get feedback.
Record videos to share their ideas with the school community.
Write a persuasive pitch about their innovation.
Create a pencil/paper or online Glogster.edu poster to explain how their innovation works.
