**Activity Collections for Math Student Circles**

Pedagogically, MSC facilitators should foster an enjoyment of mathematical thinking through creating a highly engaging, collaborative, supportive Math Circle culture that supports participation by all. Problems should be low floor, high ceiling, and should promote deep conceptual thinking and the development of mathematical habits of mind. The SF Math Circle has a wonderful description of their pedagogical approach. Organizers should also check out our MSC Toolkit for additional tips.

Below you’ll find collections of some of our favorite Math Student Circle activities!

## Mondrian Art Puzzles

You’re Mondrian’s mathematical boss. Instead of allowing Mondrian to randomly draw rectangles and colors -you lay out requirements: 1) Mondrian must cover an N by N canvas entirely with rectangles. 2) Every rectangle in the painting must have different dimensions. 3) Mondrian must use as few colors as possible, and...

## Bubbling Cauldrons

Place our numbers into the cauldrons in ascending order – you can choose which cauldron each one goes in. However, if two numbers in one cauldron add up to a third number in that same cauldron, they bubble up and cause an explosion! This means that all the numbers, leave...

## Skyscrapers

Skyscrapers come in so many different sizes! Sometimes you can’t see small skyscrapers if tall ones are in front of them. Using clues about how many skyscrapers you can see from each side you look at them, can you figure out the layout of the entire city?

## Gerrymandering

Merriam Webster defines gerrymandering as “the practice of dividing or arranging a territorial unit into election districts in a way that gives one political party an unfair advantage in elections.” This activity tries to make sense of that definition using a few examples.
