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!

Who says geometry isn't everywhere??

In geometry, my students are currently working on a project where they get to pick a theme of their choice and find a series of 18 different geometric concepts encorporated into that theme. Well as I was strolling memory lane, I was looking at my wedding pics and came across this gem! How many geometric concepts can you find here?

I see.... Parallel lines cut by a transversal (in the lattice work in the frosting) and I also see 3 similar hexagons (congruent angles, different side lengths). Maybe later on in the semester we'll find its surface area and volume! Yum 

Constructions

In my geometry class, the students are learning about congruent figures. Any two triangles that have all three sides the same length, are considered congruent triangles! We are also learning how to use construction tools to prove these ideas. Watch this week's lesson here.....

Slope really does mean something....

I am constantly asked the question "What is this used for?" That same question came up yet again in our study of slopes. When we are so bogged down in crunching numbers and following procedures, we forget that numbers and variables represent real situations, and we need to be able to analyze the numbers and make sense of the problem in front of us. Can you answer the questions below? 

What does the slope of this line represent? What is the initial cost of a bike rental? How much would it cost to rent the bike all day? (Like...12 hours.... that's plenty of biking!)
