What kind of math project could you build based on the shrinking dimensions of seats on the Boeing 777?

## More On Graphing Characters

In this article, we’ll expand on the ideas of graphing characters and also look at how we can use graphs to reinforce students’ judgments.

## Goldbach’s Conjecture

Our look at math conjectures continues with Goldbach’s Conjecture, which states that all even integers greater than 2 can be written as the sum of two primes. Is this true for all cases? Another authentic, unsolved question.

## The Collatz Conjecture

A “conjecture” is an idea that is believed to be true, but has not yet been proven. They are authentic unanswered questions for students to explore. The Collatz Conjecture uses two simple rules to get from any number to 1. It seems to work for all numbers…

## Why Pi?

Pi Day is just around the corner, but the typical fare include Ï€ art projects, memorization challenges, or other activities that separate Ï€ from its real uses. But Ï€ is such a fascinating topic that it should inspire curiosity and wonder on its own.

## Big Gifts, Small Prices

What if you want to buy a big gift that’s cheap for its size? By calculating the volume of the object, we can find how much each cubic inch costs. Measured by price per volume, Thomas is 250 times more expensive than a big outdoor slide!

## Mathematical Curiosities

Sometimes you encounter that math student who is simply interested in numbers. Here are some famous (and not so famous) sets of numbers that have curious properties.

## Finding The Conflict in Math

Sometimes I find authentic data, but it doesn’t necessarily have an obvious conflict. The measurements of the Great Pyramid are cool, but where’s the conflict? What draws students in if they’re not inherently interested in pyramids?

## Conflict and Quadrilaterals

Struggling math students shut down when they’re smacked with a mouthful of academic vocabulary right away. So lower the barrier of entry. Ask students to identify the conflict between two shapes, rather than defining “congruent sides” and “bisected diagonals.”

## Math Project: Box Office Totals

As a teenager, I loved monitoring the weekend’s box office results. This kind of data is exciting, oozing with built in conflict. It sets up questions that require math to answer.
