The Fifth Grade Biome Project!
The oldest had to use all manner of Jedi mind tricks to wrap the outside of the shoebox. I think he used about 60 square feet of wrapping paper trying to figure it out. I resisted the urge to take over or even step in to direct, but just barely.
Fifth Grade ends with the standard Math and Reading EOG tests, plus a bonus Science one. More standardized testing. Awesome.
