Let's Do Math - Adding & Subtracting Fractions with Cindy Aossey - Shared screen with speaker view

Hello Everyone, Lisa Riggs, KCM RC
Hello everyone from Bowling Green!
Hi everyone! So glad you are joining us.
Beautiful graphic to symbolize the mathematics concepts. Interconnected ideas. Love the Lamon book. Time to get a new book! Here comes Amazon!
Every time I attend a KCM training I build up my Mathematics Library.
It's amazing how many great mathematics books there are for learning and teaching!
I tried to do halves to make 1 2/4+3/6=1
4/8 + 3/6 = 1
2/1 + 6/3 = 4. Starting looking for what might = whole number answer
3/6 + 4/8 = 1I started with creating different versions of half to get up to 1.
I did 3/6 +2/4=1
Start with a whole number answer and find fractions that add up to that
3/6 + 2/4 = 1, thinking about what would make 1.
1/2 + 3/6=1
6/3 + 4/1 =7
4/2 + 6/1=8
6/3 + 2/1 = 4I took my previous equation and used inverse fractions but realized I had created 2+2 and I needed a 4 in my answer, so I adjusted my second fraction so that 4 could be in my answer.
I liked the improper fractions so I tried another one 9/3+8/4=5
my high school niece and my daughter who in 3rd year med school saw this and quickly started giving me answers! I told them they were stealing my thinking ! 8/4+ 9/3=5
I really like the top-heavy fractions, too!
2/8 + 3/4 = 1
knowing equivalencies is important
I like Cara brought up improper fractions too.
Equivalency is a REALLY big idea in mathematics... all the way through!
If you came in after the start... here's the info for today:Today’s slides:https://www.kentuckymathematics.org/docs/kcm_virtual/KCM_Virtual_Middle_School-Cindy_Aossey-presentation.pdfToday’s activity handouts:https://www.kentuckymathematics.org/docs/kcm_virtual/KCM_Virtual_Middle_School-Cindy_Aossey-handouts.pdf
18/2 + 3/5 = 9.6
38/4 + 2/8 = 9.75
54/9 + 7/2 = 9.5
I had to think about the decimal in the answer. I thought it was my limiting factor. Can't use 10 so I needed a think about what fraction would reduce to a decimal for tenths. Hmmm... still pondering.
63/7 + 4/8=9.5
27/3 + 4/5 = 9.8
18/2 + 4/6 = 9.7 I'm rounding my answer
81/9 + 4/5 = 9.8
63/7 + 1/2 = 9.5
27/3 + 4/5 = 9.8
72/8 + 5/6 = 9.8
81/9 + 3/6= 9.5
27/3 + 4/8=9.5
Using a fraction that is equal to 9 first
Lots of people trying to get the whole number 9 as an addend
19/2 + 2/5 = 9.9
OOOOO.... 27/3. OOOOO 4/5....
In the first trying to get to 9
Looks like everyone started w/ whole # nine and then added a decimal. Then looked for fraction greater than one that would = 9 and then looked for another fraction to = the decimal they chose.
Used 9 and 8 twice
so much fun!
Great for students and us as well1
I didn’t think about that I used 9 twice when I had it in my answer!
Is openmiddle.com a free resource?
It was great to see all your different solutions coming in!
I had that happen to me as well!
Yep, it's free!
It is a free site, MeiLing.
I had more perseverance with the second problem.
I post an open middle problem on my chalkboard wall for my kiddos at home to solve! Love the resource.
KCM is a friend of the Open Middle author, Robert Kaplinsky. You will love the site.
You are amazing, Cindy! Loved everything
TY. Also, can jamboard be used with any tablet?
Jamboard is embedded in Google Drive-- so it will work on any platform that will do Google docs, etc.
(2x1) + (1/4) + (3/4) + (3x1/2)
There is an app for iOS called Jamboard that is from Google. I’m downloading it now on my iPad.
It is so fun to get new tools in each of the sessions! Downloading now:) Awesome, Rachel.
the app on ipad is awesome, you can write on ipad and it shows up on computer (esp great when no touchscreen on pc)
That is great to know, Chris!
That is awesome, Chris! This would be great for virtual learning and using screencastify to record your writing without using the mouse.
Thank you Cindy!
Hi everyone! Dee from KCM here- In Georgetown, KY. I will be monitoring the chat today.Today’s slides:https://www.kentuckymathematics.org/docs/kcm_virtual/KCM_Virtual_Middle_School-Cindy_Aossey-presentation.pdfToday’s activity handouts:https://www.kentuckymathematics.org/docs/kcm_virtual/KCM_Virtual_Middle_School-Cindy_Aossey-handouts.pdf
Thank you, everyone!
Thanks so much.
Thanks for opening up your presentation to all teachers. I learned so much...very informative!

Thank you so much!
Thank you so much.
Thank you Cindy! I just bookmarked so many new resources. This made me think!
Very helpful session, thanks Cindy
Thank you, Cindy. This was great!
Thank you so much!
Thanks everyone for joining us today!
Thank you! It always good to learn with Cindy! Thinking how to use these resources across different grade levels.
Thanks Cindy and KCM! Great job! Nice to have something fun to think about!
Awesome!! Thanks Cindy!
