Alabama Math Standard: 2.OA.C.3

Use concrete objects to determine whether a group of up to 20 objects is even or odd.

How Many Will There Be? Pyramids

Give kids a taste of a sequence, let them build an understanding, and then see how far their predictions can take them.

Gr 2-4

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

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 1, 2, 3, 4, 7

Math Curiosity: Odds & Squares

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

Gr 1, 2, 3, 4, 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: Collatz Conjecture

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

Gr 1-6
