Equivalent Fraction Pizzas

Thanks for all the sweet comments on my post about my Cluttered Classroom!  I can't wait to get started organizing my room.  Anybody want to donate to the organization fund? Kidding....but seriously?

As you guys know, we have been working hard on fractions since we got back to school.  Fractions are a huge part of our curriculum, and they will be even bigger next year with Common Core. So I wanted to make sure my class had a really firm grasp on the fractions concepts.

On Friday I wanted to do a little more with ordering fractions and introduce equivalent fractions.  Ever since I saw the idea of Fraction Pizzas on Pinterest  (Click here for the original pin), I knew I had to do it.  I adjusted it a little bit so we could discuss equivalent fractions.  So I did this by having each table divide their pizzas into different fractional parts. I had originally planned on making copies of circles and drawing in the lines for them, but I decided to let them do that to review equal parts.

I have my kids sit in groups of 4 so it works perfectly!  I have 5 groups of 4, plus one little island (poor guy he just needs some space) So I assigned a fractional part to each table, so when we were done crafting, we had pizzas split into halves, fourths, eighths, thirds and sixths.





I use Kagan strategies in my class, and I love using these table mats.  I of course did not buy them, because I said to myself, "Oh I can make those!"  You can download them too for free at my TpT Store.  

Anyway, there was a point to that I promise, with the Kagan Mats, each student at every table has a number.  So I was able to form groups easy peazy by just grouping together the 1s, 2s, 3s and 4s.  So each group had each fractional pizza.  

The students studied each others pizzas and I gave them a chance to each talk about their pizzas.  Then they had to order the slices in order from greatest to least.  Of course, they wanted to race to see which group could do it the fastest!  




Then, I used prompting questions to have them start a discussion about equivalent fractions.  It was great to hear their discussion! 


At the end of the lesson, we came together and discussed our observations.  We listed our observations on the Smartboard and then the students wrote down their observations on an index card. 



It was a great lesson and so much fun!  


Well, I need to do some planning for the week.  So off I go, I will be trying to stay off Pinterest during this time.  No promises though!
