Alabama Math Standard: 4.OA.B.4.b

Determine whether a whole number in the range 1 to 100 is prime or composite.

Math Curiosity: Ulam Spiral

What if we make a huge spiral of numbers and then highlight only the primes? Well, a bunch of weird patterns show up!

Gr 1-4

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

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
