Cool Website!

Check out the cool website Mr. Cooper just sent me. It's all about cell size and scale factor.

Click here.

Mr. Cooper's Giant Skeleton


Mr. Cooper's growing skeleton started off at a height of 23.5 cm.

One student predicted the skeleton would be 141 cm tall in 96 hours.

Does this seem possible? What might the 600% represent?

Can our little family go bowling?

Mr. Cooper has generously lent us his real-life bowling pin as a reference point for our tiny bowling pin set. Using what you know about the dollhouse, talk to me about if this bowling set is appropriate for our tiny house.

Quotes that are blown out of proportion...

Here is a quote from the book Laura recommended: The Two Princess of Barmarre.

"I'm a bit older than you are, but not a great deal older. I'm seventy-eight. If I were human, I'd be just about seventeen."

My birth date is May 9, 1978. Can you tell me how "old" I'd be if I were in this guy's family?

Just how tall is a house?



As part of our Dollhouse Challenge, you'll need to determine the scale factor between a real house and a doll house. I'm 5 feet 3 3/4 inches. Can you estimate the height of my house? It can be a little tricky with a split level, so be sure to talk about how you're making your measurements.

Dollhouse Challenge





Posted by Picasa



So, my little Alex loves his new dollhouse, but he has one small problem. Can you use the materials I've brought to class to create furniture that fits his house? Be creative and resourceful. (oh, and be mathematical) Prove that your additions fit using what you know about scale factor and proportion. One last rule: Only recycled materials allowed! :)

My Reading Goal




Last year I set a New Year's goal of reading 200 books or 60,000 pages. I had just finished a nice long winter break full of great reads, so when I made my goal I think I may have overestimated. It's October 13th and I've only read 76 books! I've been keeping track of my books and my page numbers in my reading journal. So far, my cummulative page number is 27,838. I'm hoping to finish my current book tonight, so I can start reading the book Larua recommened during SSR time tomorrow. Currently, I'm on page 284 of 353. When I finish, I will have read 77 books this year. If I finish this book tonight, how many pages will I have to average on a daily basis to meet my goal on December 31st? How many books will I have left to read? If I'm only concerned with meeting my goal, what kind of page-lengths should I look for when I pick my books? Can you tell me the average number of pages I've read each day up to this point? Can you tell me the average number of books per week? Most importantly, do you have any reading suggestions?!?

Mental Mento Math by Colleen

Please welcome our first guest writer!!

Note: Try to do all of these problems mentally. Writing down the answers to keep them straight in your head is alright, but do the problems in your head.

You are on a long road trip. The boredom is starting to get to you. To pass the time, you take stock of what food you have. You have 5 carrots, 10 apples and a package with 15 rolls of Mentos.

Being a dedicated math student, you decide to figure out how many Mentos you can have. Here are the facts you know:

  • Each roll of Mentos has 14 Mentos in it
  • You are sharing the Mentos with 2 other people
  • You have 20 hours of driving
  • You will have two meals in those 20 hours, each 45 minutes long (you will not be eating Mentos during this time, nor will you need a Mento for 15 minutes after the meal)
  • 5 Mentos have already been eaten

You want to make the Mentos last until you reach your destination. Now figure out:

  • How many Mentos do you get total?
  • How many Mentos can you have per hour?
  • How long would you need to make a Mento last so you don't go 5 minutes without having a Mento in your mouth?

Extra Brain Stretchers

2 hours into your trip, you eat one of the apples. Now you are full for half an hour. To still finish all of the Mentos by the time you reach your destination, how many should each person get?

4 hours into the drive, you are stopped by road construction. You stay there for an hour and a half, and eat the same amount of Mentos that you would in 2 hours, as does everybody else. Now how many Mentos per hour does each person get?

15 hours into the drive, you fall asleep for 25 minutes. During that time, your sister sneaks a Mento per every 5 minutes you are asleep. Now how many Mentos does everyone get per hour?

Half an hour from your destination, you stop at a gas station and your sister buys a Snickers bar. She says that you and your father (who is driving) can split the remander of her Mentos. To finish all of the Mentos in time, how many Mentos do you and your father have to each eat?

Grading, Grading, Grading! When will I be finished?


It just took me 32 minutes to grade Core 1's warm-up papers. There are 22 students in this class. There are 20 kids in Core 2, 20 in Core 3, and 24 in Core 4. Two kids were absent today. How much longer will I be grading? It's 5:29pm, will I finish in time to watch the beginning of "So You Think You Can Dance" at 7:00pm?

*P.S. I'm making a Tom paper for tomorrow...You're gonna love it!

How Much Did My Dinner Cost?



My Task: To take these items and make Roasted Sweet Potato and Apple Soup.

Your Task: To figure out how much dinner costs.

The details:

Granny Smith Apples 0.81 lb @ $1.48/lb (but I only used one!)
Sweet Potato 2.8 lbs @ $1.28/lb
Yellow Onions 0.45lb @ $0.79/lb
Celery $1.18 for a bunch, I only used 1 of the 10 stalks

The following recipe will make enough to serve 8 people. Dane and I were the only ones enjoying this masterpiece and we each had one serving. How much did last night's dinner cost?

The recipe (From Real Simple/October 2008) I know, I'm a little behind the times...
3 lbs sweet potatoes
1 tablespoon olive oil
1 onion, chopped
1 celery stalk, sliced
1 apple thinly sliced
salt & pepper

Heat oven to 400 degrees. Prick the potatoes with a fork, place on baking sheet, and roast until tender, 40 to 45 minutes. Heat the oil in a large saucepan over medium-high heat. Add the onion, celery, and apple and cook, stirring occasionally, until soft, 10 to 12 minutes. Halve the potatoes, scoop out the flesh, and add to the saucepan. Add 6 cups of water, 2 teaspoons salt, and 1/2 teaspoon pepper. Cook until heated through, 8 to 10 minutes. Puree the soup in an blender. Work in batches. Add water, if necessary, to reach the desired consistency.
