That the students learn how to generate multiple, fast ideas through time-intensive model building.

Prepare materials for building models and set an alarm on the clock. First round could e.g. be 10 minutes. Time is reduced as the students warm up and get comfortable with the process.

It is often a good idea to agree on several rounds where the students build a new idea each round. The rounds have to be intensive; the students need to be under pressure and the more rounds they complete, the better. The students should become better at rapidly visualizing their ideas in a simple way. After building the solutions/ideas/concepts, the students present these to their team members. Whether they present their models after each round or at the end of the whole process is optional. This technique is targeted towards ideas development and they should therefore be prioritized and processed.

The students can also choose to further develop or add onto each other’s models. Through visualization, the challenge and the possible solutions become clearer than when the students brainstorm on post-its.

Rapid Prototyping – 1,000 Ideas helps the students loosen up and kick-starts their creative mindsets. The technique is good to use after one of the other ideas development techniques, where the design teams have developed many new ideas and have opened up to creative processes.


  • Preparation, building materials are laid out, the timer is set.
  • Rapid Prototyping – 1,000 Ideas could be e.g. four rounds of 10 minutes (e.g. reduce time for each interval).
  • The ideas/models are presented in the design teams, discussed/analyzed and the models the students want to continue working on are chosen.

Execution time
1 lesson.

Stop watch, building materials: Cardboard, paper, string, rubber bands, straws, plastic, tape, scissors, glue, crayons, pens, post-its, etc. The teacher can also choose to give the students less materials, e.g. LEGO or modeling clay, skewers and string. This helps the students focus on how to visualize their ideas in the fastest and simplest way.

The students work at their stations or somewhere else according to their needs and split up into groups of 2-3 people.
