Bring a little art into your math class as you begin to use the Pythagorean theorem and your students first meet irrational numbers.
The HAT tessellation
An Einstein aperiodic tile has just been discovered. Find out what that means and why it is significant. Plus – play with the tiles. Do you want to tile your shower floor with these? Could a tile setter pull this off?
The Times Square Ball
What does truncation mean? How is the Times Square Ball related to an icosahedron? Let students learn about the crystals and the LEDs that create this beautiful construction.
Before the holidays (16 activities)
We have tons (well, 16) of activities to bring to your class in this last week before the holiday break. Movies, science, art, cooking, economics, weather and the logic of calendars. Enjoy!
Lots of Cranberries
In this activity, students learn about how cranberries are grown and harvested; estimate their size and quantities; and see what they can deduce from published statistics.
Total lunar eclipse
On the morning of November 8, 2022, many of us will be able to see the last full lunar eclipse until March 2025. Luckily, many of us will be able to see the eclipse pretty close to when we would…
How many gumballs are there?
Get your students thinking, estimating, and calculating.
The James Webb space telescope and the Hubble
There have been outstanding images coming to NASA from the James Webb Telescope. Take some time to compare the Webb to the Hubble telescope that has been sending images to Earth since 1990. Look at what is different and what…
Shooting for Three
The NBA court has a 3-point line that separates how many points a player will earn for his team by making a basket from outside of that line. Teams have been shooting more and more three’s, but should they be and why?
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…
Wrapping presents on the diagonal
In this activity students determine if this method for minimizing wrapping paper is actually more efficient then the traditional method. For a hands on learning experiment, have students actually wrap a small rectangular prism using any available paper in both the traditional and diagonal methods. Then let them compare the two quantities of wrapping paper and decide which method uses less paper and by what percent.
2 New Macy’s Parade balloons
Students figure out the dimensions of these two new balloons using Macy’s hints and judging from the handlers’ sizes.
Collecting the most candy
Use your student’s Halloween enthusiasm to do a study on volumes. We’ve created an activity that asks students to calculate the volume of candy containers that are silly and intriguing. Skip the cone and the sphere to make this activity…
Steepness and fall hiking
Combine colorful and cool fall hiking with a little mathematics about percent grade change. What is a steep grade? Why is it in percent? How does grade change relate to slope?
