Coordinate Points on Graph: First Quadrant (February 14-17)

Every Mathlete was given a picture such as the Cat in the Hat or a Lion on a coordinate plane in quadrant one (all positive coordinates). The challenge this week is the have the children master naming any point on a plane with two coordiantes, the horizontal and the vertical.

3-Digit Numbers Whose Digits Have a Sum of 6 or ___ (Feb. 7-13)

Recently, I was tutoring an 11th grade student in SAT math. She was unable to answer a question not because she couldn't add; she had no strategy; she did not look for patterns; she failed to use a systematic approach to problem solving. 

Here's the question: how many three-digit numbers have digits that sum to the number 6?

Platonic Solids using Four Color Theorem (May 23 - 26)

We explored the five Platonic Solids discovered by Plato in 400 BC.  Each of these polyhedra, the Tetrahedron, Hexahedron, Octahedron, Dodecahedron, and Icosahedron, have congruent regular faces. They are the only polyhedra known that have vertices that are spaced equidistant from each other if inscribed in a sphere.

Incidentally, certain math foundations are offering $1 million to the mathematician who discovers a sixth such solid.

We built these solids using the rules of coloring maps: no adjacent edges may be the same color.

Target Number (May 16 through 18)

Preparation: Take a deck of cards and separate out all of the face cards (eliminate

Jacks, Queens, and Kings);You should have 40 remaining cards from Ace to 10 in

four suits.

 

1. draw 5 cards face up.

BIZZ BUZZ BANG Multiples of Primes (May 9-12)

BIZZ BUZZ BANG is one of my favorite games to play as it tests your knowledge of multiples with mental math.

BIZZ represents multiples of 3; BUZZ represents multiples of 7; and BANG represents multiples of both 3 and 7 which kids soon learn are multiples of 21. Sitting around a circle, participants count from 1, 2, and then BIZZ (instead of 3), 4, 5, BIZZ (instead of 6), BUZZ (instead of 7), 8, BIZZ (instead of 9), 10, 11, BIZZ (instead of 12), 13, and so on .... but when you get to 21 you say BANG.
