2D to 3D Thinking

In Ms. Geppert’s technology class, fourth-grade students are stretching their thinking from 2D to 3D, in preparation for upcoming lessons on 3D printing.

The students were given cards that had flat, 2D diagrams displayed on them, that guided them on where to place Keva planks to create various angles. Over the course of the lesson, students needed to create three different perspectives, and check their designs with the photo examples they were given.

This exercise helps students think about all 3 dimensions, which prepares them for their intro to Computer Aided Drafting (CAD), and how to think through alignment and design in 3D.

Ms. Geppert said that “it is pretty common for a student who is new to CAD software to make a creation and think it is aligned until they change the perspective on the screen and then find it’s leaning. Before we print, we want to have thought ahead about these kinds of design flaws.”
