We are thrilled to announce that Geometiles, a multi-award winning set of interlocking tiles is getting a new look. We are launching a limited edition of Geometiles Glow in the Dark — just in time for Haloween, the first big holiday of the school year.

Halloween is an excellent opportunity to take advantage of students’ enthusiasm and inject some spooky fun into math activities. Think of constructing stars and ghosts that shine or a pumpkin made of regular, orange Geometiles with glow-in-the-dark eyes.

Halloween Math: Glow in the Dark Spinners
Spinners are not only loved by kids but can be a great STEM learning tool as well. From studying spinning colors to probability, the possibilities are endless.
Invite you students to create a spinner made of glow in the dark and regular Geometiles. Above is a spinner in regular light.

Halloween Math: Geometric Jack-o’-lantern
In the spirit of Halloween, invite kids to create geometric jack-o’-lanterns. Introduce or discuss different shapes, like circles, squares, triangles, rectangles, pentagons. Discuss areas and find a way to count the number of polygons used to construct the solid. The solid is called a rhombicosidodecahedron, and here’s how you construct it with Geometiles.

Halloween STEM Activities: Glow in the Dark
1. After students complete their Glow in the Dark Math activities with Geometiles, invite them to find out the science of how the glow in the dark stuff works.
2. Experiment with different sources of light to see which are best absorbed by the phosphor. Ultraviolet light charges in the fastest time. Try direct sunlight, energy saving bulbs, and standard bulbs.
