Big Thinkers

In this series of lessons, you’ll be exploring a process known as the "double-diamond". It's end-to-end problem solving, applicable to any area of the school, work, or life, reaching far beyond just design. It helps you back up your thinking and start from real problems, understand the root of them, and determine the correct problem to solve. From there, you’ll learn how to ideate and come up with interesting solutions, plus techniques for narrowing them down to the strongest.

Lesson 1

Discover & Define

This lesson will be focused on finding problems to solve, and understanding their causes.

Each student should work to brainstorm about problems they face day-to-day, aim to create a comprehensive list, then narrow it down to one they’d like to move forward with solving. This will cover both the discovery and definition phases of the double-diamond.

Lesson 2

Develop, Part 1

In this lesson we will be exploring potential solutions to their problem, using the ‘Crazy 8s’ brainstorming method. We will go around the class and have each student read out the problem they’ve decided to solve and causes behind it.

Each student then brainstorms ideas, and presents them to the class who will help them to pick their best idea by voting using sticky dots.

Lesson 3

Develop, Part 2

In this lesson we will be working out a flow for your solution using ‘journey mapping’.

Figure out the core moments of engagement on post-it notes. What prompted them to take action? What happened just before the core moment? What will happen just after? What happens in the long-term? Then organise these moments in a timeline, creating a storyboard.

Lesson 4


In this lesson, we will be visualising our solutions. Working from the student-created storyboards, they will create a more refined visualisation designed to help others understand their solution.

Lesson 5


The grand finale! This is where students will share their finished presentations with the rest of the class.
