Arizona Math Standard: 3.MD.C.7.c

Use tiling to show that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.

Gr 3-5

Pascal’s pattern-packed triangle is a potent puzzle for pupils to ponder.

Gr 3-5

Parentheses: How big of a change can they make!?

Two tiny parentheses. One expression. How big of a change can they make? Bigger than you think.

Gr 3, 5, 6, 7

Same Perimeter, Different Area For Rectangles

Can two rectangles have the same perimeter but… different areas!?

Gr 3, 4, 6, 7

Math Curiosity: The Coloring Problem

Math Curiosity: Waring’s Conjecture

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

Gr 1-5

Discovering Pi With Sticky Notes

Pi is mysterious and strange! Why not let students discover it on their own?

Gr 3, 7, 8
