How many stars are in this image and how did you count them?
What do you think this activity might be about? What do you wonder? How much would you pay for this piece of art? How much profit is involved in this sale?
What can you tell about a snowflake?
As a snowflake falls from the sky, its crystal grows according to the humidity and temperatures of the air that it passes through. In this activity, students interpret a graphic that clarifies that growth and try to deduce what conditions…

Tree for Springtime
Here in the Northeast, flowers are blooming and trees are leafing out. We thought the creation of a tree that grows before your eyes might be akin to what is going on all around us. What do you see that…
12/16/20 – Pythagorean Triples
This would be a good date to play with Pythagorean Triples. Pythagorean Triples and coloring – Pythagorean triples are not only handy for students to recognize but produce some interesting and lovely patterns. We’ve combined a little coloring with our Pythagorean…
Ravensburger huge puzzle
Students surmise what the difficulty of a jig saw puzzle entails and use rate calculations to estimate finishing times. They try to confirm whether doubling the number of pieces really increases puzzle completion time by a multiple of four.
String design, ellipses, and orbital mechanics
Artistic way to encourage understanding of a conic section. Participants physically build an ellipse by choosing two foci and sketching the figure through a loop of string. While stitching an elliptical string design they puzzle about varying the foci spread and the loop length to create more extreme ellipses and are intuitively introduced to the measurement of eccentricity.
Mixing colors with food dye
It’s time to dye eggs … or make a rainbow colored cake. Proportions, saturation, hue and shade.
Pascal coloring and modular math
Clock math, 1,2,3,4,5,6,7,8,9,10,11,12,1,2,3,4,5,6,7… is modular math. Let your students learn about the usefulness of modular math as they color and explore Pascal’s Triangle. Very pretty math!
