Students will tackle Waring's curious conjecture from 1762: all odds are either primes, or can be written as the sum of three primes. After 250 years, we still don't know if it's true or not!
In this final part of the caffeine investigation, students will analyze advertisements, and then create a public service announcement.
Students, now armed with data about five caffeinated beverages, will survey a set of peers and/or adults to uncover misconceptions about caffeine.
This is the first of a three part interdisciplinary math project. Students will be investigating caffeinated beverages, dangers of caffeine, and how advertising affects our perceptions.
Can all perfect squares be written as two primes added together? In this exploration, students will discover interesting relationships between these types of numbers.
Have students tackle the classic "Seven Bridges of Konigsberg" problem - can you cross each bridge exactly once?
We'll explore money and test scores as we determine which is more useful: mean or median?
It seems like there's always at least one prime number between two perfects squares. But is this always the case?
Prime numbers seem to appear randomly. How do we reliably find primes without dividing every number by every possible factor? The answer is thousands of years old…
Twin Primes are prime numbers that have a difference of two. Mathematicians think there are an infinite number, but aren't sure yet. Have your students look for patterns as they dig into the Twin Prime Conjecture.
From Prufrock’s Advanced Common Core series, we introduce the Triangle Sums exploration.
A sample puzzle from the Factors and Multiples edition of Prufrock’s Advanced Common Core Math Explorations series.
In this video, students will learn a way to visualize fraction multiplication.
Students will purchase a large item on a credit card, and calculate the cost of interest if they only make the minimum payments.
A set of challenging fraction puzzles from the series Advanced Common Core Math
Dividing by fractions is counter-intuitive and confusing. We'll use several animations and sketches to develop students' conceptual understanding of this operation.
Students will experiment with sticky notes to find the area of a circle and, along the way, discover pi!
Let students discover the relationship between diameter and circumference by exploring some famous circles.
Create a fun classroom activity where students don't just analyze inaccurate graphs, but create their own and try to mislead their classmates.
Use Google Earth to capture authentic data to answer an intriguing question.
