Okay, so there's new movie and it's got something about tesseracts in it, and the book was by Madeleine L'Engle, then this is what you've been looking for! This is the only set of plans on TeachersPayTeachers for a four dimensional cube, better known as a "hypercube" or "tesseract." Includes easy to cut out plans for the following: • blank hollow hypercube • hypercube with printed graphics, including the various names and properties of a hypercube. • a "filled" hypercube which has a cube inside the hypercube. Comes complete with photographs and step-by-step instructions on how to build the models. All you need is a pair of scissors, photocopier, glue stick. Flux capacitor not necessary! MORE CONTENT FOR THE SAME PRICE! • I added an activity sheet where students use patterns to predict how many points on would find on all cubes up to the dekaract, the ten dimensional cube. More to come ! For more information on teaching students about the fourth dimension, see Mary Carr's excellent Geometry Enrichment for Flatland - The Movie.
