Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

Los Momentos de Mixing in Math son actividades de 5 a 10 minutos que mantienen a los chicos ocupados, aprendiendo sobre el mundo, y usando matemáticas por su cuenta.

This website contains several activities. Mixing in Math Moments are activities that take 5-10 minutes that keep learners occupied, learning about the world, and using math on their own.

En esta actividad, los aprendices exploran la simetría haciendo papel picado, una decoración común en México para las celebraciones.

In this Cyberchase activity, use grid coordinates to share secret pictures with a friend. Color squares of a grid to make a picture (like a smiley face) that you keep hidden from the other person.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners slide shapes to create unusual tiled patterns.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.

In this math lesson, learners follow step-by-step directions for making tangram pieces out of folded and torn paper. First, learners read "Grandfather Tang's Story" by Ann Tompert.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.

This PDF contains 12 calendars (12 months). Each month contains activities about math. Things to do on familiar holidays (like July 4), less common holidays (like Backward Day), and any day.
