 * Valentine Heart Attack! **

Students will find their name on the butcher paper. You will need your pencil and a calculator.
Take a data worksheet. One for each group. Come up with a group name that it symbolic of a Valentine theme. Put your Group name and your Individual name on your data sheet. Estimate the total number of candies in the bag of hearts before opening the bag. Once you have your estimate written down and expalined the basis of your estimation, you may open the bag and start separating the candies into colors. Fill out the entire data worksheet! Once the entire data worksheet is completed, show me the data sheet and I will send you to a computer.

Once you are on the computer: Open. Go to File > Save As > type in your group name on the file. Fill in your information that you have collected in your groups about the candy colors into the charts on the Excel file. Now open the file. Answer the questions on the "Valentines Heart Attack" file as a group! Put your cursor after the question on the page and type your response in complete sentences right into the document. Now read through your whole paper and make sure I can tell what you are talking about!! Have a teammate check your spelling and thoughts. Raise your hand when you are done and I will come and help you print!

HAPPY VALENTINES DAY!
** Complementary vs. Supplementary **

"Under the microscope, I found that [|snowflakes] were miracles of beauty; and it seemed a shame that this beauty should not be seen and appreciated by others. Every crystal was a masterpiece of design and no one design was ever repeated., When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind."

Wilson "Snowflake" Bentley 1925

You and your partner are going to pull up your ‘smart tools.’ Find the protractor smart tool. Once you have the protractor up, you are going to go here (http://www.its.caltech.edu/~atomic/snowcrystals/photos3/photos3.htm) and measure different Bentley Snowflakes. Your goal is to find both supplementary angles and complementary angles within the snowflakes.

Once you have found supplementary and complementary angles it is your turn to make a snowflake. See if you can make a snowflake with supplementary and complementary angles! Create your snowflake here (http://snowflakes.barkleyus.com/index.html).

Once you are proud of your snowflake, make sure your protractor is pulled up so that others can take a gallery stroll and come around to measure your snowflake. They will be looking for supplementary and complementary angles.

SUPERIOR SUPER BOWL MATHEMATICS Sunday, February 6, 2011 is the Super Bowl. Even if you are not a sports enthusiast or you don't plan on watching the game, you can have a good time figuring out the mathematics from past Super Bowl competitions. For example, what is the probability an NFL team will win vs. the probability that an AFL team will win? How would you figure out the probability? To answer this and other interesting data facts research past Super Bowl statistics by first going to this website: Super Bowl for YOU

(Download a recording sheet for you and your partner to share. Complete the sheet on the computer; at the end of each day's work session you will save the document on your desktop to be opened and used the following day. You will have no more than three days to complete the entire investigation. On the third day you will print your recording sheet and give it to the teacher.)

You will have ten minutes to read some of the interesting history behind the Super Bowl. At the end of the ten minutes you need to find the chart that shows the teams and their scores for the past Super Bowl competitions through 2010. You will use this information to complete the following investigation:

1. Categorize the winning teams as NFC or AFC 2. Calculate the percentage of times an NFC teams has won the Super Bowl; calculate the percentage of times an AFC team has won the Super Bowl. Based on the percentages, which conference NFC or AFC is more likely to win this year's Super Bowl? How much do you think knowing which conference a team belongs to affects the outcome of the game? ==**Cheerios Toy Probability ** == This activity will take place in two parts.There will be teacher-led discussions and instruction for each part. FIRST you will conduct an experiment based on the instructions at the [|Cheerios] link. Answer the first questions in your math log. Remember to date the page, and title it Cheerios Toys. Mrs. Cunningham will give you a copy of the recording page, a die, and will discuss the instructions with you. Answer the follow-up questions in your log directly following the beginning questions. NEXT you will go to the [|APPLET] link and conduct the same experiment using the random toy generator. Do this twice. LAST Be prepared to share your results on the class line plot and to share your thoughts, conclusions, and questions in a class discussion.
