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.

Multiplication Tables: Can you beat your time? (May 2-6)

What do all Mathletes have in common? They exhibit such a positive competitive spirit that they can't wait to beat their time on any activity. 

Mind Benders: Numbers with Clues (April 11-14)

Mind Benders challenge the children to look at a number critically and think of it in the context of certain clues.

For example, the number 26 is best known by English speakers as the number of Letters in the Alphabet. So the clue "26 L in the A" usually triggers the association.  Another easy one is "365 D in a Y."

The first sheet attached are 25 Mind Benders I created with math in mind.  The second one is more challenging and should be attempted with the whole family.  Try not to look at the solutions.

Mobius Strip (April 4-7)

We explored the simplest geometric shape with one face and one edge.  The paradox is that this is a three dimensional polyhedra. It has revolutionized belts for engines and has been used to define black holes. I proved to the children that a conventional fan belt in an engine or computer only uses one side of the belt and wares out quickly.  A Mobius belt uses twice the surface area and lasts twice as long.
