B&P Finale

posted Apr 30, 2013, 4:01 AM by Tony Francescutti   [ updated Apr 30, 2013, 4:03 AM ]

Hey Mathemagicians!

To show your mastery of B&P III, I'd like you to create a learning and review opportunity for a friend. If you can create fantastic questions and your friend can answer them, then you are a B&P III master!

The general guidelines go like this:
1. The questions must be written in the form of a word problem.
2. The questions must post some challenge, but should not be so difficult that they are frustrating. 
3. You'll not answer your questions and you have no idea who will, so make them clear and exciting.
4. You must plan your questions out on a piece of paper and then transfer them to a Google Doc.

These are the type questions you must create:
1. Addition or subtraction of decimals.
2. Multiplication or division of decimals.
3. A sales tax or tip problem.
4. A shopping discount problem.
5. Anything you'd like that has to do with decimals, fractions or percents.

Materials and resources:
1. B&P III book.
2. Any old work we've done.
3. Sal Kahn.
4. Your friends.

Timeframe:
Questions must be generated by the end of the class today.
This learning opportunity will be answered by a friend tomorrow.

Good luck, my friends!
And remember... do not give 110% effort. It's not possible and you wouldn't feel good afterward. =P

Division of Decimals

posted Apr 8, 2013, 4:49 AM by Tony Francescutti

Division of decimals is very similar to long division of whole numbers! Check out this video and then this video as explained by Khan. He suggests that you get rid of the decimals. Check out his cool method! These videos are a little bit longer, but stick with them.

Here are the exercise options:



Multiplying D-d-d-decimals!

Yay! I can hear your enthusiasm! 

No, really. This is kind of fun ;)

Let's start our with a Khan Academy video. Remember, when you are multiplying decimals, it's not much different than multiplying whole numbers. Do the problem first and then worry about the decimals after.

Start out with this one and after that, check out this video that deals with word problems.

After you've watched the videos, this is your practice. Work through it with your personal whiteboards and I'll talk with you about how it went. We'll even look at a few practice problems together, so you can share your knowledge.

Here's a cool little animation that'll help you remember where to place your decimal point at the end. If you are uncertain, just think about our estimation strategies.

If you have a problem like:

31.09 x 3.93 = 

When you estimate, think about it in terms of 30 x 4, because 30 is close to 31.09 and 4 is close to 3.93. If your actual answer is around 120, because 30 x 4 = 120, then you're close and you'll be sure of where that decimal is supposed to go!

The assignment that follows all of this is on page 24 & 25 in your B&P III books. It's problem 2.3.

Dun Dun Duuuuun! Decimals!

Okay, okay. I suppose decimals aren't all that bad, especially considering the fact that you are all fraction masters by now. The one thing you need to remember, above all else when working with decimals is... PLACE VALUE! (This is an unscientific and unproven statement, but Mr. F. says so!) You need to be thinking, where is the decimal, what what is the place value of each digit in the number that I'm dealing with.



Hmmm... Let's give Mr. Khan a chance to share how he goes about working with decimals.

Watch this!

What did you think? I think you can all handle adding decimals. To prove it, grab your personal whiteboard and give this exercise and this exercise a go. 

Ermahgerd! You are masters!

Now, on to subtraction. Watch those decimal points! Hold those places with zeros if you need to!

Here's video one and then video two.

When you've followed along with both videos, try the exercises with your whiteboard. 

Here they are. Numero uno and numero dos.



If you truly ♥ this, here's you're challenge. Even is you this makes you feel like  and unhappy snowman, give it a go.

Wrap Up Dividing Fractions

posted Mar 7, 2013, 4:24 AM by Tony Francescutti   [ updated Mar 7, 2013, 4:31 AM ]

We are going to wrap up our B&P II division of fractions studies today. 

Here is your template to complete today's assignment on Pg. 54 in your B&P book. Make a copy of the template, remove the word "template" and replace it with your initials, and locate it in the proper folder of your Google Drive. 

If you finish early, here's some practice and here is some word problem practice. Again, think about dividing fractions. What does it mean?

Another option would be this one game from Sheppard Math. Other games are off limits during this time. 

Dividing Fractions

Good morning, Connected Mathemagicians! It's time for some more fraction work. In order to be successful today, you will have to set aside at least 8/9 of your brain power for this. That still leaves 1/9 of your brain for daydreaming and being goofy, but only 1/9 or it won't be a productive day. I'll be checking in tomorrow to see how knowledgeable you are.

http://www.cartoonstock.com/newscartoons/cartoonists/mfl/lowres/mfln375l.jpg

First, let's review what we know. It's been a while with our winter break and all, so a quick refresher is in order. ** Use your personal whiteboard to work things out.

1. Do you remember how to add fractions? Check this video out first and then try out your skills. What does it mean to add fractions? Think about it.

2. How about multiplying fractions? Here's a video to watch and after you've done that, some practice... and some more practice. What does it mean to multiply a fraction? Think about multiplying whole numbers to understand multiplying fractions.


Now, on to the new stuff! Let's divide fractions.

3. Here is your video to check out. I'd also like you to watch this one because it deals with word problems. Here's your practice and here's some word problem practice. Think about dividing fractions. What does it mean?

** If you run into negative numbers, give it a try. We haven't talked about that idea yet, but you can challenge yourself to figure it out.


Good luck, my marvelous mathemagicians! 

Fractions Continued 1/28/13

posted Jan 27, 2013, 7:07 AM by Tony Francescutti   [ updated Jan 27, 2013, 7:29 AM ]

Today you mission is to review something about fractions and then continue with our new learning about fractions. We are slowly stepping away from our benchmarks and moving on to more challenging and "less-friendly" fractions.



Step 1: Make sure that you have your personal whiteboard and a dry erase marker available. You will need it to work through some of the problems. 



Step 2: Quick review!





Step 3: Reinforce your knowledge!


Practice  *This is tricky! You will need your to work through them and make sure they are reduced before giving your final answer. 



Step 4: Read this! If you finish early, write a story about fractions. I will be meeting with you soon.





Post Meeting: Do NOT go on until we have met. Thank you.


Multiplying fractions! Hmmmm... What does that mean? Can you answer that question now?


Percents 1/22/13

Today you will start class by reviewing percents!

What words do you know that have the word "cent" in them? Hmmmmm...




Step 1: 
Watch these videos in order:







Step 2:
Awesome! Cool videos, huh? Now, I want you to practice a few times. Try this for a while. Go through it at least two times. Check it out and see how it works, but stay on percents!

Go here!




Step 3:
Visit our Wallwisher and post two unique thoughts. Be creative, but be focused! To make a post, just double click anywhere on the board.

Here it is!
