Jack’s Playground Plan Extension Activity
Create New Toy Designs With Tinkercad and hold them in your hand with a Merge Cube
On the Time to Innovate page in Jack’s Playground Plan, students use their innovative designer skills to create a new toy.
In this extension activity, students will use Tinkercad to create their new toy with this free, web-based 3D design platform. Find Tinkercad at www.tinkercad.com.
When their new toy is ready, you can have a Toy Showcase by walking around to see everyone's creative designs.
One more fun extension within Tinkercad is to hold their toy using the Merge Cube and augmented reality (AR).
