Let’s Share!
Each group needs to post their chart/charts in a designated area of the room.
Each group will present their standard to the rest of the group. Each member in each group, must present one piece.
![Page 14: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/14.jpg)
Reflecting on my learning/Think-Pair-Write-Share. . .
What I now understand about the Common Core Standards for Math Practice is. . . .
This understanding is important because. . . .

Problem Solving in Mathematics
Part 2
![Page 16: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/16.jpg)
Spend It!
You will need two handouts. Price sheet Recording sheet
![Page 17: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/17.jpg)
The objective of the game is similar to “The Price is Right!”
I will give you an amount of money that you can spend. You will choose your items, total them and try to spend all of the money in your budget. The closer you get to spending all of the money, the closer you get to winning.
So if I give you a budget of $35.00 and you spend $34.59 you did a pretty good job. If you spend exactly $35.00, you WIN. If you spend $35.01, you LOSE.
Ready? Here are the rules.
![Page 18: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/18.jpg)
Here are the rules of the game.1. You must choose five different items. Write these items in the first branch of your Tree Map.2. Write the price for each of those items in the second branch of your Tree Map.For Example:
![Page 19: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/19.jpg)
Here are the rules of the game.
3.You may buy as many of each item as you want. 4.Record the number of units and calculate the total for those items. 5.Add this information to your Tree Map
You may use a calculator!For Example:
![Page 20: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/20.jpg)
Finally total all of your costs. Feel free to continue to work toward winning the game. Give yourself no more than 6 minutes to play.
Good Luck.
![Page 21: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/21.jpg)
So how did you do? Now that you have finished the game, I want you to think about the thinking behind your strategy. Analyzing how you approached this problem is your Frame of Reference.
So let’s add to your Frame of Reference.
![Page 22: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/22.jpg)
When students solve a problem, they should answer these three questions.
![Page 23: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/23.jpg)
So let’s add the answers to all 3 of these Frame Questions to your Spend It Tree Map.
![Page 24: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/24.jpg)
First, think about the strategy you used to make your decisions about what to buy and how many of each item you chose. Think about WHY you chose the items you chose.
Did you
1. Start with prices that were large and then use the lesser priced items to get close to the total?
If so, your strategy was to think NUMERICALLY.
![Page 25: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/25.jpg)
Did you
Combine items in order to get whole numbers?
If so, your strategy was to think NUMERICALLY using Base 10..
$3.00
$3.00
![Page 26: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/26.jpg)
Did you
Think ALGEBRAICALLY?
I have $20.00 to spend and I have to buy 5 different items. Therefore, I should spend about $4.00 on each item.
$20.00 5 $4.00
![Page 27: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/27.jpg)
If you used any of these strategies, you were thinking like a
Mathematician.
These strategies INFLUENCED
How you approached the problem.
![Page 28: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/28.jpg)
If you chose your items based on any of the following:
“I picked the items I like.”“I picked items for breakfast. You can’t have
breakfast without coffee!”
While you might have gotten items for a great breakfast, you did NOT think like a
mathematician.
![Page 29: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/29.jpg)
Add your strategy to your
Frame of Reference
I combined items to get to whole
dollar amounts. I used my
knowledge of base 10 and
number sense.
![Page 30: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/30.jpg)
Now let’s think about the actual math skills and processes you needed to know in order to solve this problem.
![Page 31: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/31.jpg)
Identify the math skills you used to solve
this problem and add them to the
Frame of Reference.
They might be something like…
I used adding and multiplying
as well as subtracting.
I also used “guess and chec
k” as well as estimating.
![Page 32: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/32.jpg)
Many students struggle with math vocabulary, so identifying key terms you need to know is another important meta-
cognitive skill for problem solving.
![Page 33: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/33.jpg)
I used adding and multiplying
as well as subtracting.
I also used “guess and chec
k” as well as estimating.
I need to know what “cost per unit” means.
![Page 34: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/34.jpg)
Finally, students should be given time to reflect on how they solved a problem, what they learned in the process and how they might improve
their problem solving skills using their understanding.
![Page 35: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/35.jpg)
I learned not to get distracted by irrelevant information. I didn’t need to focus on the type of item. I should have just paid attention to the
numbers.
I need to think about how to
solve the problem,
before rushing into just trying
to solve it.
You can solve a problem using a lot of different strategies.
![Page 36: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/36.jpg)

Notice that the information in the Frame of Reference is really the most important part
of this problem solving.
Students can then use the statements in their Frame of Reference as well as the
information they record in the map itself to show their understanding of math concepts
and problem solving.
![Page 38: Unpacking the Standards for Mathematical Practice Professional Development September 16, 2013.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e255503460f94b1461c/html5/thumbnails/38.jpg)
I am incorporating the math standards
of practice into my daily instruction.
