Building...Rethinking...Rebuilding 3-D Structures

Building our 3-D structures has officially BEGUN! Armed with only 15 straws, 5 pipe cleaners, and 3 feet of tape (because building materials are expensive in the real world!) we set out to make the strongest 3-D structures possible. The strength of our structures will be tested by stacking gram weights on top of a square of mat board that our structure MUST be able to support.

Henry and Ella thought about why their design
would be strong

We're realizing that the original design plans we had need to be revised! Even though we know the triangle is the strongest polygon, it has still been tricky to figure out how to incorporate the triangle into our 3-D designs. Even though we used our whole Math Workshop today to build, many people still need to revise and rebuild their structures tomorrow. Building takes a lot of time!

revisions to their original rectangular prism design
Ty'onte and Max have decided to build a triangular prism
