Pi Day Activity- Make Pi Day Bracelets!

This Friday (3/14) is Pi Day!  Pi is a mathematical constant referring to the ratio of a circle's circumference to its diameter.  It's an irrational number, which means that it goes on forever and never shows a repeating pattern.  Every year it's celebrated on 3/14 because the first three digits of Pi are 3,1, and 4.  Now if you're looking for an easy way to celebrate Pi day, we've got a great collection of Pi Day Inspired Activities.  Today I'm sharing these nifty Pi Day Bracelets!  What makes this a great Pi Day Activity?  Well, the beads are strung according to Pi's digits. (Cool, right?)   It's a great way to combine math, art, and crafting!

Make a square and cube bubble

We are definite bubble lovers over here.  With the colder weather outside, we've just been blowing them at home over a beach towel.  Recently I learned that bubbles didn't have to just be spherical shaped.  They could also look like squares and cubes too. What? No way! 

Yes way!  Behold!  A cubic bubble!

Whoa.  It's bubble play for us older folks! Keep reading to see how we made different shaped bubbles:

Healing math

I was having a rough day yesterday and feeling quite glum. Thankfully, a friend called and cheered me up with some kind words and a math question. (She's studying to be a teacher.) I'm not sure why, but working on her math question cheered me right up.

Here's the question:

We know that
A pair of suspenders and a pair of socks cost 18 dollars.
A tie and a pair of socks cost 22 dollars.
A tie and a pair of cufflinks cost 25 dollars.
A shirt and a belt cost 37 dollars.
A pair of cufflinks and a shirt cost 33 dollars.
A belt and a pair of socks cost 17 dollars.

Given all this, how much does each item (pair of suspenders, pair of socks, shirt, tie, pair of cufflinks, and belt) cost?

Have fun!

Pumpkin play (Part 1)

This past weekend hubby, Baby Chuck, and I were invited to a pumpkin carving party.  We had a lot of fun and I learned a few new carving tips and tricks. 

Here's my finished pumpkin:
My homage to pumpkin pi.  (Get it?  Get it?  Oy vey, I'm too corny. )

Five finished pumpkins sitting in a row.

Let the countdown to Halloween begin!

Pathways to love

With Valentine's day just around the corner, I thought it might be fun to include a Valentine's day inspired math brain teaser.

Can you figure out the number of paths that spell the word "Love" if only vertical and horizontal moves to adjacent squares are permitted?





By the way, here's the answer to yesterday's math brain teaser.

Did you figure it out?



Answer to be revealed tomorrow!

Virtual cutting

Last week I found myself happily lost in a maze of math brain teasers.  Here's one that I really enjoyed: 

Make one cut to the first figure (a) and then rearrange the pieces for the second figure (b).



Answer and next math brain teaser will be revealed tomorrow!

Admire the beauty (again)!

Do you remember learning the Pythagorean theorem ( a2 + b2 = c2 ) when you were in school? Well, here's a visual way of showing it.  Eureka.  Isn't it beautiful?

Is anyone out there a quilter?  I bet this would make a really lovely (albeit nerdy) quilt.

Admire the beauty!

My hubby recently showed me a book of different math proofs performed through pictures.  That's right, no words or numbers neededWho knew it could be done?  Here's one that I sat pondering awhile. Then, eureka! I got it.  And now I tell you, dear reader, admire the beauty!
