Today the students were given a 2-D copy of a shed (see 2nd picture below) and asked to recreate it on the computer using the FABLAB Model Maker Software. We used a printout from the Balanced Assessment series that asks students to create an advertisement for a shed that is depicted in net form. The problem, as set forth in the Balanced Assessment materials, gives students a chance to cut out and glue together a pre-made model shed, measure the model accurately, figure out the measurements of a real-life shed from the key and then write an advertisement for the shed. We decided to ask the students to create it to scale, then build it with our digital fabrication tools, and compare them as a more authentic assessment of the measurement piece of this task. We also wanted the students to explore various parts of the software (with little formal instruction) to see what they would discover, use and share with one another.

The following are pictures from student work in the lab:

Then they began building with the program. IMG_7960.JPG They had to find where to change the settings from inches to centimeters, they had to adjust for the fact that the paper model was 3.5 cm and they couldn't figure out how to adjust the size to a half of a centimeter.

Some explored with the patterns you can put on the sides of the buildings.IMG_7958.JPG

Here's one example of a completed shed from all sides:

Our next step is to run them off on the silhouette machine and compare them--we'll have an authentic assessment of how well we could recreate a model by how close the actual 3-d model is to the paper model we used as a pattern.
