Welcome to Lesson 3 of our design thinking lesson series. Starting with LESSON
Welcome to Lesson 2 of our design thinking lesson series. Starting with Lesson 1, this set of 7 lessons will show you how to walk a group of learners through a design challenge of your choice: a fun, engaging, and relevant way to introduce them to new tools, skills, and career options.
Lesson 3: Ideate: How can we use sketching to record and share our design ideas? How can we use collaboration with others to refine our design ideas?
Note – part 1 of this lesson is a detailed drawing and sketching review, part 2 is on brainstorming ideas. If you feel your students need extra time on learning how to sketch, consider turning parts 1 and 2 into their own lessons.
Many careers involve the ability to ideate and come up with design solutions for a job: plumbers utilize ideation as they consider how to run pipes through a building, horticulturalists ideate and sketch designs of which plants should go where.

Tools & Materials
Material List
- Design Thinking Template and notes from Lessons 1&2
- Scrap paper for drawing
Tool list
- Pencil
- Ruler and/or straightedge
- Set of twelve to sixteen large blocks or small plain boxes
- Computer or tablet with word processor and sketching app
- different 3D objects to sketch, eg, cylinders, rectangular prism, cube, triangular prism, etc.
Optional
Procedure
-
Rewrite the following six steps on the board if necessary: Step 1 Empathize, Step 2 Define, Step 3 Ideate, Step 4 Prototype, Step 5 Test, Step 6 Make, Step 7 Share and Reflect.
-
Hand each student a few sheets of scrap paper. Explain to them that this lesson will be about learning how to express their design ideas to their peers. Note: If students are not yet familiar with sketching 2D and 3D shapes, consider splitting this lesson into two sessions, one for sketching and one for ideating.
-
Start by leading students through a basic sketch warmup: show them the GIFs here or try it on the board for them to follow along. Use about half a page for each exercise, and spend about 1 minute or so on each (or longer if necessary). Remind students that this is a warmup, that they’re welcome to make a mess of the paper, and it will be recycled at the end of the exercise.
-
Give students a movement break.
-
Have them try sketching a more complex 3D shape, such as two boxes stacked on each other, or a toy car. Help them visualize the complex shape as made up of simple 3D shapes in the previous step.
-
Set up four different “sculptures” with a few large blocks or boxes each, leaving lots of space all around them. Tell students to be careful not to bump or move the sculptures.
-
Let students circulate through the room to make orthographic (2D: top, front, side) and isometric (3D) sketches of the block sculptures. Some students may get through all four sculptures, some may only get through one or two.
-
Have a quick discussion with the class again about ways to contribute to a positive environment where people are comfortable sharing their ideas. Remind them that they ALL have the right to be heard and respected, which also means a responsibility to listen to and respect their peers. Record a list of their suggestions on the board so they can refer to it while brainstorming and collaborating.
-
If needed, review the design challenge, and the success determinant and parameters lists they developed in lesson 2.
-
Give them 5 or more minutes to individually sketch a minimum of three of their own product ideas (on the design template or on scrap paper).
-
Divide the class into small groups. Give them another 5 minutes to each share their three product ideas with the group, then note any feedback they get for each sketch on their design template.
-
Ask students to discuss all the design ideas amongst their group with the goal of choosing one of their three ideas to move ahead with in their design process. Encourage students to help speak positively about designs while helping their groupmates choose which one to move ahead with.
-
Once every student has chosen their favourite design idea to move ahead with, you could add one last level of collaboration by allowing the groupmates to give each idea one “wish”, or “constructive suggestion” to improve on the design ideas.

Sketching warm-up
3D isometric sketches
2D orthographic sketches
Practice sketching objects
Part 2: Ideating
Extension Challenges
- Encourage students to think about and look for different materials that they might be able to use in their design, and make some notes on the benefits or drawbacks to using each material.
- Ask students to consider what tools and materials they might want or need to learn more about in order to build their product.
