Oops...Almost Forgot Friday's Post...

Friday's lesson was 2.1: Analyzing Graphs and Tables. The objective (focus) of the day's lesson was to use tables, graphs, and descriptions to compare information and make decisions. Before getting started in the text, we shared ideas of how we compare data in our lives every day before making decisions. For instance, when buying video games we may look at the rating on the game and the game's popularity among other teens before buying it. When purchasing an item of clothing we may compare prices and styles. Someone also mentioned the idea that before buying a new skateboard, you may look at the type of wood the board is made out of to know whether it will be a good board or not. All these were great examples of looking at information to make a GOOD decision. We took this a step further and even discussed ways in which people try to sell membership packages and other sales deals to adults (my students in the future) that may turn out to be taking advantage of the buyer. We talked about using our math savviness in the future to be sure not to "fall" for gimmicks out there that will just "steal" our hard earned money. We want to be smarter than Miss Kohr's friend was with the membership package she bought this summer, right?!? :-)

In Lesson 2.1 students looked at two different bicycle rental companies cost information to help our five "friends": Malcolm, Sidney, Celia, Liz, Theo decide which company to use for their 3-day bike tour. Students pointed out that Adrian's rates were constant, meaning no matter how many bikes you rented, the cost per bike remains the same. This is shown in the graph by the points on the graph being spaced evenly throughout the entire line on the graph (constant rate). When looking at Rocky's rentals, students pointed out that as you rent more bikes, the cost per bike goes down. For instance, if you only rent 5 bikes the cost per bike is $80 ($400/5 = $80) but if you rent 50 bikes the cost per bike is $24 ($1200/50 = $24). Students concluded from this information that Rocky's wants large groups of bikers to rent from them (thus why they give deals to big groups); whereas Adrian's does not give any deals for more bikes rented. Lastly, students decided that when looking at the best shop to rent bikes from the decision depends on the number of bikes you are renting. Meaning, if you look at the graph and table, you will see that Adrian's is the best deal for bike rentals until you reach a point of renting over 30 bikes (then Rocky's becomes the best deal). I mean really...how smart are Miss Kohr's math students, eh?!? SOOOOOOOO SAVVY!!! :-)

Oooh...almost forgot...students took another timed multiplication test on Friday. All scores are posted in the comments section on Pinnacle. Check it out!

Reminders:

From Friday, September 14-Wednesday, September 18 we will be raising money for Everett Gotway's Memorial. We were deeply saddened by the loss of one of our Hollenbeck family members and would like to purchase a bench and plaque in his honor. Anything you can do to help would be greatly appreciated! Thank you in advance.

Students need to be sure to come to class prepared (every day) with their graph paper, pencil, book, and binder (and any homework or papers that need to be turned in). If students continue to arrive unprepared, a phone call will be made home and students will be issued a detention.


Today's homework:
Challenge: p. 36 #2 a, b, & c
All other classes: Lesson 2.1 p. 31 a, b, c, & d(1)

Also: remember to...
~Redo any assignments necessary (you have one week to redo work in math)
~KEEP STUDYING THOSE MATH FACTS...you could have another timed test any day now :-) :-) :-)

Question of the Day: The people of New York City celebrated the centennial of the Brooklyn Bridge in 1983. When was the Brooklyn Bridge built?


Good luck my savvy students!!! Remember, the first student to answer the Question of the Day correctly will get a small prize from me the next day! :-)
