Today's Google Doodle!

Check it out and learn about Shakuntala Devi, the first "Human Calculator!"

From ABC news:

High school memories of math class may come flooding back to people who visit the Google homepage. Today's Google Doodle features a familiar olive green calculator screen, with thesearch engine's name written as upside down numbers. The reason for the doodle? The birth of a calculator, though not the one that you punched numbers into to get through trigonometry.

Instead, today honors the birth of Shakuntala Devi, pictured to the left of Google's logo. Though Devi lacked a formal education growing up, she astounded people with her ability to crunch large numbers. "At the age of 6, I gave my first major show at the University of Mysore," she once said, according to The New York Times. "This was the beginning of my marathon of public performances."

It may be that during one of those performances that Devi got the nickname, "the human computer." In 1977, at Southern Methodist University in Texas, Devi raced a computer to figure out the 23rd root of a 201-digit number. The computer took 62 seconds to find the answer, while Devi found the solution in 50 seconds.

Unlike the old computer, Devi's abilities are still astounding to this day. An old clipping from The New York Times archives shows other arithmetic problems that she solved in under 20 seconds. In addition, she earned an entry into the 1982 edition of the Guinness Book of World Records for needing less than half a minute to both calculate and say aloud the product of two 13-digit numbers.

Devi died earlier this year from both cardiac and respiratory problems. She was 83 years old.

Pretty darn Awesome if you ask me!

LCM and GCF review

Today we went over how to determine if a problem is a LCM or a GCF problem.  We looked for words and questions that are good hints and then figured out a few LCM and GCF problems.  In small groups or partners you created your own GCF and LCM problems (which we will use as part of a review worksheet on Wednesday!)

Here are the examples!

The quiz will be Friday of this week!   Please study the LCM and GCF problems as well as multiplying and dividing fractions to prepare!  Use your study guide and old homework assignments to help you!  I'll miss you guys tomorrow!  Enjoy the day off and please encourage your parents to vote!
