Avril had to build a dodecahedron and use it to calculate surface area for math. (She's about half-way done with Math-U-See's Pre-Algebra.) There was also dodecahedron in Phantom Tollbooth, one of the books she had to year for Challenge B this year. So she added faces to the surfaces so it would match the dodecahedron in that story. She's been keeping this interesting, handmade trinket on her school desk just for fun the of it.
