(You can check out these posters and so many other fun activities for introducing fractions, here!)

I mean do you ever catch your self saying… “Man I went over that vocabulary too much!” Yeah… me neither…

To introduce the idea, I used these awesome fraction models . Then we made a reference of all our equivalent fractions for one-half on our white board. Students worked on their own personal white boards while I recorded.

For small group, I pulled a few students to my table and we worked together again to review this concept.

I also found this great little freebie from Jan Lindley to help with my reteaching of this concept! You can check it you here!

Now, while most of my students worked to create reference pages in their math ISN’s, I had one friend who really struggles with cutting and pasting. Our ISN is his Achilles’s heel. He asked if he could tell me a story instead… I was like uummm…SURE!?

Now you might not be able to read his story, but you can def see all his equivalent fractions!

Moral of the story… don’t be afraid to allow your students to show their learning in their own way. Did he prove that he understood equivalent fractions? For sure! Bonus: he nor his teacher were frustrated with the other for not completing the assignment. Allow for differentiation folks… your student’s abilities will blow your mind if you allow them to access the information in a way that they can relate.

Finally we ready to move on to comparing fractions. Now comparing fractions with like denominators was easy (pie and cookies always work well!)

But comparing fractions with different numerators and denominators… that proved to a bit trickier…

So after LOTS of discussions with reasoning, we completed this fun comparing fractions activity…

To complete the activity, each student got 3 sets of a certain type of food item. They were challenged with writing their own comparing story using the food items as inspiration.

I LOVE that multiplication trick for comparing fractions – GENIUS!

Fractions is our next unit. Thanks for sharing. Will be pinning to make sure I use these in a few weeks!

We've been working on fractions too and love the comparing fractions freebie. Thanks for sharing it!

Leigh, Its great to see the progression of the skill coming from a first grade standpoint! You are so right about never enough vocabulary practice!! The trick at the end is the best!!

Great post:)

I've been teaching Math for 33 years and I have always used 'cross multiplication going up' to compare fractions. (You are simply finding the numerators of two fractions with a common denominator [demon1Xdenom2].) When the kids forget the method, I simply cross my arms in front of me with my index fingers pointing upward. They instantly come up with the correct answer.

Math Instructor says

How does teaching cross multiplying to compare fractions help students make sense of what they are doing… Yes gives them the right answer but do they know why? This method does not help develop number sense related to fractions.

Leigh- The Applicious Teacher says

I think if you re-read the post you will see that I discuss how important it is for students to use reasoning when comparing fractions. I only suggest the butterfly method at the end as a way for students to check their reasoning. A "quick" check if you will. I agree, only using cross multiplication does not teach number sense, but it is effective in checking our reasoning. Thank you so much for stopping by!

Great lesson and pictures, and you even covered differentiation.

You made my list of the most shared fraction resources on the web according to buzzsumo. You can see the post here.
