Math
There seemed to be a little confusion about the strategies to use to calculate the change. My apologies, sometimes it's difficult for a supply teacher to understand the classroom teacher's expectations. When you calculate change, make sure you can do it using two different strategies (not including the good old-fashion algorithm).

Strategy #1 is adding up using a number line.

Strategy #2 is making an easier question by shifting the difference.
   $40.00 (-1)  $39.99
- $28.55 (-1) -$28.54
                                  $11.45
There was a third strategy mentioned in the textbook, subtracting in chunks. We didn't really go over this method, but if you understand it and it works for you, then feel free to use it!

Please complete the following review questions for homework in your green math notebook. DO NOT USE A CALCULATOR. Feel free to use an adding strategy or use an algorithm (pencil and paper).

Winter Olympics Double Bar Graphs:

If you have not recorded your data for your bar graphs, it can be found at:
https://www.pyeongchang2018.com/en/game-time/results/OWG2018/en/general/medal-standings.htm

#1

Country	Gold	Silver	Bronze
Canada
Country of Choice

One of the bar colours would be Canada, the other bar would be your country of choice.
The horizontal axis would have the different medals.
The vertical axis would have the number of medals.
Choose an appropriate title.

#2

Canada	Gold	Silver	Bronze
Men
Women

One of the bar colours would be men, the other bar would be women
The horizontal axis would have different medals.
The vertical axis would be number of medals.
Choose an appropriate title.
Don't worry about "X", means team sports.

#3

Sports	Canada (Total Medals)	Country of Choice (Total Medals)
Figure Skating
Free Style Skiing
Snowboarding
Alpine Skiing

One of the bar colours would be Canada, the other would be your country of choice.
The horizontal axis would have the different sports (you can use any sports, I just chose these ones)
The vertical axis would be total medals
Choose an appropriate title.

Science
Today in Science we talked about VARIABLES. What are variables?

There are three different kinds of variables:

Why are variables important when you are conducting a fair test? Think about all the variables you controlled today when you conducted your fair test using the basketballs. Be ready to record them in your notebook tomorrow. Everyone did an excellent job today recording and performing the investigation. All groups recorded their results e.g. ___ basketball bounced higher. But what CONCLUSIONS can you make? Hmmmm  Conclusions are what you learned. Usually something useful. Why would knowing which ball bounces higher be useful?

An interesting question came up today about why one ball bounced higher. Do you know why? We tried to control all the variables except the type of ball. Think about the different forces acting on the ball as it is dropping.

We also talked a little bit about INSULATING DEVICES. What  is an insulator? Any material that does not conduct heat very well or materials that don't let heat pass through them.  What kind of materials are good insulators? We will conducting a fair test comparing insulating devices of different groups. Start looking around the house for materials that are good insulators. Your challenge is to keep a warm cup of water as warm as possible for 10 minutes.

Word Study
We have had so many students away, that we will not have our word study test tomorrow. We will have a period to get caught up with bell work and word study. For those that have all their work completed, you will have a STEMS challenge tomorrow.

Reminders:

• School mass tomorrow at St. Nicholas @ 2:00. Everyone is welcome.
• Stations of the Cross next Thursday, March 29th @ 1:15 pm. We will be presenting this important and holy service to the school. Everyone is asked to wear black. We will continue to practice tomorrow. Everyone did a wonderful job today.
• Store your indoor shoes neatly at the end of the day and keep your personal belongings organized. Thank you!
