TEKS Math Standard: 3.4.I

determine if a number is even or odd using divisibility rules

Fizz Buzz: A Counting and Divisibility Game

Ready for a tricky counting and divisibility game?

Gr 3-6

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

Evens and Odds – Addition and Subtraction

When we’re adding and subtracting, do evens make odds into evens? Do odds make evens odd? Which one has… more power!?

Gr 3-4

How Many Ways: 2 Digit ÷ 1 Digit = 1 Digit

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

Gr 3-4

Math Curiosity: Odds & Squares

Why does the sum of the first 5 odds also equal 5 squared?

Gr 1-4

Math Curiosity: Waring’s Conjecture

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

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 3-6

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: Collatz Conjecture

The Collatz Conjecture: start with any number and get to 1 using just two rules. It seems to always work…
