Help for teachers and students!

My normal weekday night consists of planning for hours to prepare for the next day at school. My dearest hope is that my students are at home studying and practicing for as many hours as I am! I love when I come across tools that can be used inside and outside the classroom, than can aid both teachers AND students in accomplishing their goals.
Check out http://www.studyblue.com
It is a website where teachers are able to make digital flash cards. Some features...
*students can log in and practice with the pre-loaded cards the teacher creates
*students can take quizzes once they study and track their progress
*teachers can collaborate and share materials
*ready-to-print flash cards and review sheets are instantly created once the flashcards are made
*iPad and mobile app available
*students can be invited via email, social networks, or text messages
*class stats are recorded to help teachers assess progress
I just printed my first set of flashcards, ready for my kids to use tomorrow. Let's see how it goes!

today I saw a Tetracontakaihexigon....yeah okay....

My geometry student have been studying polygons. We are pretty familiar with triangles and octagons, but some multi-sided shapes can have wildly outrageous names. Talk about a tongue twister!

Internet Connections

My algebra classes have been practicing their skills using an awesome website called Khanacademy.org. They are able to watch videos, take quizzes, earn points and rewards, and even track their progress. If parents are stressed about being able to help their kids with math homework, Khanacademy is a great resource to watch videos and explore topics you haven't learned about in years. As a teacher, it has helped me find a new way to assess my students' learning. Check it out!khanacademy.org

Another website I have recently begun to explore is IXL.com  (cleverly named!) where there are hundreds of practice exercises to choose from. With the way information is being processed now-a-days, (with almost everything happening on-line!) it only makes sense that our kids' learning can be on-line and interactive as well. See for yourself here: IXL.com

Happy studying!

In the spirit of thanksgiving!

A large Thanksgiving banquet served between 500 and 600 people. The dinner rolls came in baker’s dozens (packages of 13). After everyone had been served a roll, there were a number of empty packages plus one open package with 10 rolls left. The pies for dessert had each been cut into ninths, and after everyone had been served a slice there were a number of empty pie
tins plus one pie tin with 4 slices left. The tables in the banquet hall each had
room for 15 guests. All of the tables, except one, were full.

How many people attended the banquet? How many people were seated at
the table that was not full? How many pies were there? How many packages
of rolls?

Oh conspiracies...

While browsing the internet I came across this YouTube video from earlier this year.
Even if you can't sit through the 12 minutes, the claim is that the North Pole is moving at a rate of 160 miles every 6 moths. My algebra classes certainly have been working on conversions this year, so my question is, according to this claim, how many inches is the North Pole moving per second? Assume 30 days in a month.
Now whether or not you believe this is true, I'll leave up to you....

Some examples of geometry in everyday life!

Here are examples of geometry found around the classroom, presented by GC.

And here is an example of geometry found while watching hockey, made by RW.
These are just two examples of the amazing projects my geometry class presented last week. Great job class!
