Homework Assignment

Reflect Back and Look Ahead:

• You will learn how to make engineering drawings and use them in the design process
• You will learn how to make a CAD model and use it in the process of design

Challenge:  How do you design and create a challenging and entertaining cube puzzle?

Multiple Perspectives:

• John (TexPREP student)  I made all of my puzzle pieces the same color so that it was more difficult to solve.  I wanted to have the hardest puzzle to solve.  Students can practice on the easy ones and then try mine out.
• Jennifer (freshman engineering student) I put different textures on my puzzle pieces using pictures of my cat.  I think that cat lovers will enjoy solving my puzzle.
• Mike (Computer programmer) I really enjoyed solving the cube puzzle.  Some are easier than others.  I got familiar with the tools on an easy one and then had fun with some of the more challenging ones.  The only thing that I didn't like is that it doesn't let you know when the puzzle is solved.  It is a great way to work on 3D visualization skills.  Keep up the good work.
