60th Edition of Math Teachers At Play Carnival

The number sixty happens to be the smallest number divisible
by the numbers 1 to 6. Also, it has the honour being a unitary
perfect number, ie it can be interpreted as being the overall sum
of its unitary divisors (excluding itself). Give this a try to convince
yourself:  1 + 3 + 4 + 5 + 12 + 15 + 20 indeed equals 60.

Students of science (in particular chemistry) would almost
definitely be acquainted with the 'Buckyball', which is also known
as Buckminster Fullerene- an allotrope of carbon possessing 60
carbon atoms in each molecule. It was named after the genius who
had earlier designed a geodesic dome bearing an uncanny
resemblance to the C60 structure. Here's a little visual feast for the eyes:

Did you know besides the widely used decimal, binary and
hexadecimal systems, a sexagesimal system (employing 60
as its base of computation) also exists?  Previously used in
Babylonian Mathematics, it is now responsible for time and
angular measurements (think seconds, minutes, arc seconds
etc). How about a counting sample from the ancient times to
appreciate things a wee bit more?


Without further ado, let the 60th MTAP carnival begin. Welcome.

Over at Math Mamma writes, Sue Vanhattum shares her little
mulling session over the unproven Collatz Conjecture. In her
personal opinion, she feels this is definitely something worth
investigating and also serves as a puzzle kids can enjoy, at the
same time practice multiplying by 3/ dividing by 2.

At Random Walks, John Chase reviews a presentation (by
Alison Bank) on Math Is Not Linear and extrapolates things
with his own set of experiences. Fractals: A Different Kind of Geometry written by Guillermo Bautista at Mathematics And Multimedia aims to reveal the intuitive notion of fractals.

Coming right up, a celebration of pedagogy.

Three Acts: Basketbola Preview at Prime Factors gives
readers an extensive sneak peak of Tom Ward's blockbuster
lesson plan. In his own words:

"Basketbola is an algebra II lesson in which students use graphing software to model the flight of a basketball. They use their mathematical models to predict whether or not the ball will go in - the student who is the best predictor gets to add their basketball shot to next year's contest!"

The kitchen is a great place for young kids to learn about
geometry, measurements, fractions and other math related
stuff as Jacquie Fisher explains in her post Great Cookbooks for Kids and Math Fun In The Kitchen at KC EDventures.

Who says charity and math don't go hand in hand? Susan
Carpenter has rallied her young charges in a service project
to feed hungry families in 100 Cans of Food by the 100th Day of School, and therein you will discover mathematics learning is very much alive in this initiative.

If your students are extremely frustrated when dealing with
fractions, Jennifer Smith's downloadable fractions flippable
templates made available in her post Fractions are Fun! 
could possibly make understanding a whole lot easier.

At Denise Gaskin's Lets Play Math! blog, Math That Is Beautiful  has posted a lovely video (by Cristóbal Vila of Inspirations From Maths ) encouraging parents to sit down
alongside their children to make beautiful math together.

I reckon this is still space for one more entry, so allow me to share
a guest post written for my site earlier this year by Dr Diana S.
Perdue titled: A Math Class That Requires a Party Playlist For Your iPod? Yes, Please!

That's all folks for this current edition of Math Teachers At Play. 
Math Hombre is the destination for the upcoming April 2013
carnival, so be sure to head over there next month for more math bites.


(PS: I would like to accord a sincere thank-you to Denise Gaskins for giving me the opportunity to contribute to this blossoming math blogging community. )
