KnoTiles$14.95 Everyone is familiar with the utilitarian and decorative uses of knots, but mathematicians study knots as well. KnoTilesTM is a puzzle that serves as an introduction to the mathematics of knots and the symmetry of knot designs. All of the knots through seven crossings can be formed with the set, and the instructions contain over a dozen brain teasers. The puzzle pieces feature photographic rope images, with a second color of rope on some pieces to allow the formation of links (like knots, but with more than one strand). 105 cardboard pieces. Grades 3-12. [Add to Cart] [View Cart] |

What's more, if a face is viewed upside down, as different rightside-up face is seen! Making Faces comes with instructions that include several brain teasers plus a game using the pieces. Four reproducible worksheets cover translational and rotational symmetry in tessellations, the mathematics of combinations, and drawing 2-way faces. 120 cardboard pieces, packaged in a plastic jar.
