More Fraction Fun~Unit Fractions and Decomposing

After our start of our fraction unit, we moved onto some key vocab and models.
First, the students got 6 different pieces of construction paper (all the same size) and were instructed to divide each into a different fractional amount.
We added them to our Math Notebooks by gluing in an envelope to hold them.
I had the students label each section, which led us into a discussion about what a unit fraction was and how to decompose a number and what it meant.

They next day, students got a purple rectangle and a green rectangle-which were different sizes.

I modeled what I wanted them to do, first folding my rectangle into equal parts, and then labeling the parts.

After I had labeled the parts, I glued it into my notebook, and showed them how to decompose my whole, and the different ways I could do it.
Then, I asked the students to do the same thing-but they had to do it with sixths or bigger.

I loved leaving it open, because the kids self-differentiated. My not as secure friends stuck with sixths and eighths, while my very secure friends went up to thirty-seconds!
At the bottom, I gave the kids two fractions to decompose two different ways without the use of models as a quick let me know who got it and who didn't!

I then gave them a little bit longer assessment to see how much they retained and if they understood the concepts we've been learned so far.

We had to fix some misconceptions about equal parts :)

We're almost done fixing misconceptions about fractions and equal parts, and will be moving onto fractions of a set next...We'll see how that goes!!

Smiles and Sunshine,


  1. Kaitlyn,

    These are fantastic strategies to help students! Thanks for sharing!


  2. Love it! Thanks so much for linking up this month--and I love that your students are digging into my fraction unit. Thanks for the shout out! :)

  3. We're all teaching fractions right now! :) This is a terrific visual; love the envelope with all the models! Thanks for sharing!


Thanks for visiting and leaving a smile! :) I like to smile back via email, so please make sure you're not a no-reply blogger. :)
