TEKS Math Standard: 4.4.C

represent the product of 2 two-digit numbers using arrays, area models, or equations, including perfect squares through 15 by 15

Gr 3-5

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 4-7

Math Curiosity: Four Squares

Every positive integer can be written as the sum of (at most) four perfect squares!

Gr 1, 2, 3, 4, 8

Math Curiosity: Odds & Squares

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

Gr 1-4

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
