Indiana Math Standard: 7.NS.5

Find the prime factorization of whole numbers and write the results using exponents.

Factors and Codes: First Names (Episode 2)

Scrambled up somewhere in 161,000 is a first name. Can you find it!?

Gr 3, 4, 6, 7

Factors and Codes (Episode 1)

Let’s use factors to encode and decode words.

Gr 3, 4, 6

Math Curiosity: Klauber’s Triangle

In 1932, a leading authority on rattlesnakes, Laurence Klauber, discovered a startling pattern within a triangle of primes.

Gr 1-5

Math Curiosity: Goldbach’s Conjecture

Can any even number be written as the sum of two primes? Goldbach thought so, but we haven’t proven it… yet!

Gr 1-5

How Many Ways: Order of Operations 1

How many different ways can you make this math statement true using only the digits one through nine?

Gr 1, 2, 3, 4, 5, 6, 8

Why Is Our Calendar So Weird!?

Why are there 12 months? Why don’t weeks fit into months evenly? Why don’t weeks fit into the year evenly? What’s going on with the calendar!

Gr 3-6

Math Curiosity: Waring’s Conjecture

So, can you write every odd (greater than 3) as the sum of three primes?

Gr 1-5

Math Curiosity: Primes and Squares

Can any perfect square be written as the sum of two primes?

Gr 1, 2, 3, 4, 5, 6, 8

Math Curiosity: Legendre’s Conjecture

It seems like there’s always a prime number between two perfect squares… but is this always the case!?

Gr 3, 4, 5, 6, 8

Math Curiosity: Finding Primes

Prime numbers are unpredictable! How can we possibly find them all? An Ancient Greek mathematician found one way!

Gr 1, 2, 3, 4, 6

Math Curiosity: Twin Primes

What do you call two prime numbers who are very close together?

Gr 3-4
