How to Easily Teach Early Fractions {Guest Blog by Jenny}

Today I have invited Jenny from Little Vikings Learning to share with us one of her favorite ways to teach fractions.



Fractions are one of my favorite math concepts to teach because they are so easily seen in the everyday world around us and I find that kids already instinctively understand fractions in the real world; we just have to help them connect the numbers to the reality.  Easy Peasy. 
I always start with the most basic concepts: what is a fraction, what is it called, what does it look like in the world, and what does it look like in numbers.  Pro tip:tackle these concepts during snack time because their mouths are full (no talking) and they’ll listen to new concepts easier.  I start by reading the book “Eating Fractions” by Bruce Mcmillan BEFORE my students start eating.  As a class we then look at our whole snack item (be that a bun, banana, strawberry, etc) and show our whole unit to the people sitting near us.  We then get to eat half of it and compare our half to someone else’s half.  We make sure to note that half a banana is not the same size as half of a strawberry.  

 


I then give the kids fruit and plastic knives.  We take pictures of the fruit (or we have some already printed out) of a whole, half, quarter, etc. This means I let kids cut fruit with knives.  They love it...passionately.  Put the pictures of your cut up fruit on the board.  Use the half as the anchor for kids that struggle with the concept of denominator/numerator.  Label the half in words and numbers.  Most kids can easily recall a half and visually refer to it as “1 of 2 parts”.  They can use this idea of “number I have of so many parts” to write fractions numerically.  
I try to let each kid take pictures of their own fruit and then we’ll print the pictures for them to mount on a piece of paper.  This can easily become their personal anchor chart in a math notebook.  If printing is not easy, I’ve also called it a “fraction dissection lab” and had them write up “lab notes” that were hand drawn pictures of their fruit cut into fractions and labeled.
