Mobius strip made with clay

Week 13: Clay Möbius Strips

There are lots of amazing paper Möbius strips that are fun. You can cut down the middle, twist multiple times, make a Möbius paper chain, and try it with various materials. For a basic paper tutorial, I found a good one here. Rather than creating the classic paper strips, this week learners will be

Week 12: Galileo and Gravity

This week we are going to take a look at applied math. Learners will be given a ramp (this can be a ruler), a ball that fits on the ramp, measurement device (ruler) and a timer. With these instruments learners can investigate the relationship between distance and time as the ball rolls down the ramp

Week 11: Soma Cubes

I love Martin Gardner’s work and books that brought math to so many people in a fun and engaging way. One of the topics he covered was Soma Cubes. This week learners can create and play with this wonderful seven piece puzzle that was invented by Mr. Piet Hein during a lecture on physics. I […]

a dragon curve made with toys on the left and with lines on the right

Week 9: Dragon Curve

The Dragon Curve is a fractal that is well explained in this numberphile video. This week learners can create a dragon curve with a strip of paper, Lux Blox, Python programing, Legos or toothpicks. Paper: For paper, I would suggest using a strip of thin paper. Thicker paper doesn’t produce as many f

Week 8: Density Through Pointillism

This week we are going to look at density in a two-dimensional sense. The idea is to create two dimensional images using various densities of points. The medium and approach can vary for the classroom. Some ideas are: Sand art on a stick surface using different densities of sand (try light colored s

Week 7: Cartesian Coordinates

This week learners can get hands on with plotting. I encourage learners to investigate the history behind the Cartesian Coordinates (it’s interesting – I was just reading about it in Infinite Powers by Steven Strogatz). The idea is to plot with D&D figures, chalk, legos, or watercolors. Make art out

Week 5: Tell a Tale (or comic)

No matter what grade/age, stories are fun. This week I encourage learners to read and write math stories. Take a concept and illustrate it through the art of story. Write comics, picture stories, murder mysteries, fantasies, plays, etc. Students can act their story out, create a stop animation, or i

Week 4: Polyhedra Study

Leonardo da Vinci was an amazing mathematician, inventor and artist. His sketches in The Divine Proportion are a wonderful collection to study. Spacial awareness and being able to draw what we see is a skill that can be mastered through practice. This week, I encourage learners to sketch polyhedra f

embroidery with green string of curves formed with straight lines

Week 1: Embroider Curves with Lines

Welcome to 52 weeks of math! I will be posting a new activity every Wednesday for 52 weeks of hands-on math. Week 1 is one of my favorites – drawing with thread. In this activity, learners will play with their rulers (or thread) to create curves with lines. The idea is to have students draw […]
