Math Walks ages 3 and up
Here are some sample social media links that describe math walks and other activities we do with the youngest learners.

Elementary Grade Math Activities
Here are some sample social media links that describe activities for elementary school students.
2nd and 4th graders tiling with the recently discovered aperiodic monotile 13-sided "Einstein Hat", the first such to fill a plane with a non-repeating pattern from a single shape
1st grader building Pascal's Triangle out of blocks showing how large the numbers become
How many pieces of pizza (or uttapam) can you make with straight cuts? Check out the video of an attempt here, as well.
If you lived in a country where the coins were 3¢ and 11¢, are there a lot of amounts (like 1¢, 2¢, 4¢, 5¢, and 7¢) that you can't make? What's the largest amount you can't make?
2nd grader's notes about Traveling Saleswoman Problem and Integer Partition Problem
3rd graders estimating the number of slices of pizza or South Indian dosas eaten in the United States, among other things
4th graders made illustrated stories about fractions; one was clearly influenced by Ben Orlin who was delighted to see the story
Kindergarteners through 3rd graders touching on concepts like indeterminacy, probability, & induction, before playing with geometry in a summer math circle
Middle School Math Fun
Here are some sample social media links that describe activities for elementary school students.
The Birthday Paradox is surprising to many; Buffon's Needle provides a way to estimate π by tossing pasta at a piece of paper
Students used scissors and paper to demonstrate why any two lines (except horizontal and vertical ones) have slopes that are negative reciprocals of each other
Remarkable Math
We get amazing students who often go beyond and pursue their own exciting math explorations.
This 2nd grader made a video demonstrating the algebraic concepts of cubing a+b but by physically doing it with blocks instead of using algebra.
Students figured out that when we raise a number to the nth power, it takes n differences to become a constant, but this 2nd grader knew about and applied factorials to find the actual constant! Several students explored on their own what amounts to a discrete case of Taylor Series, studied in second semester calculus.
There is a fun "Doomsday Rule" that one can use to find the day of week for a date but you need an "anchor" day for each month. I shared a nice mnemonic but this 2nd grader and her mom made their own version in an exciting video.
Math Parties
Mathematics Institute of the Triangle hosts a school kickoff party, year-end white elephant gift-exchange, and summer get-togethers.
