Note from the author:
A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU. The outlined content above was added from outside of Formative.

Solve It! Can you arrange all of these pieces to make a rectangle with no pieces overlapping and no gaps?

The pieces have been recreated as virtual algebra tiles in a Google Drawing.
1. Click here to create a copy of that Google Drawing.
2. Arrange the tiles on the Google Drawing to form a rectangle with no pieces overlapping and no gaps.
3. Take a screenshot of your completed work.
4. Upload your screenshot to the canvas. Resize if necessary. 2
