Section 1: Viewing and Representing 3-D Objects

 

You have now had experience building models from 2-D views in a digital environment. Try building models using a variety of other manipulatives.

  • If you have access to LEGO pieces or other building materials, like sugar cubes, building blocks, playdough, dice, or anything else you can think of, you will need them now.

  • If you don't have any physical materials to build a model, you can use virtual LEGO pieces online. You can find the LEGO materials by using a search engine and the keywords “LEGO digital designer.” You can also use the 3D Object Applet from Lesson 1.
