Every year around this time, I hear the same chorus in the hallways: “My kids just aren’t getting it! Teaching fractions is so hard!” While fractions are traditionally taught in elementary and middle school, I’ve even heard from some high school teachers who say their students struggle to understand them.
In fact, leading mathematicians like Dr. Tom Dick, one of the authors for the Texas Instruments Building Concepts program, have said that a solid understanding of fractions is one of the foundations on which high school math success is built.
Teaching fractions is an essential part of math curriculum. But why are fractions so hard for kids to understand? There are three big things that trip kids up most often.
- We are often asking kids to perform a series of steps without understanding the reasons behind the steps. Sometimes, when they’re younger, students are not even developmentally ready to understand the concepts.
- Kids often develop misconceptions about all challenging topics in mathematics, including fractions. When we can help kids confront those misconceptions, learning often occurs more easily.
- Kids struggle with fractions for the same reason that kids struggle with a lot of new concepts: They just need practice.
We can help kids move beyond these obstacles. Here are five teaching fractions ideas to do the trick.
1. Get Hands On
The concept of a “fraction” is abstract and visualizing part vs. whole is a developmental skill not fully in place for some kids until middle or high school. Manipulatives can help the concepts become more concrete. I love building fraction kits with my kids at the beginning of every fraction unit I teach.
Building the kit together gives kids a visual concept on which they can build the rest of their knowledge and we use the kits throughout our entire fraction unit. I’ll keep my fraction kit taped to the board throughout my unit, and refer to it when we need to work out a problem together.
I like to build my kits with my students when they’re younger, but my colleagues with older students will often keep a few pre-purchased kits on hand for kids to turn to.

2. Use Visuals
Anytime I can provide an image to go with the concept I’m teaching, I know I’m going to be in better shape. One way I do this when teaching fractions is to ask students to create the visual on paper. This activity from Texas Instruments teaches students how they can represent fractions in a more visual way.
Using a grid-based system, the teacher uses a projector or interactive whiteboard to introduce a lesson that presents fractions (as well as fraction-based computations for more advanced students) as shapes. After the kids have seen the visual representation on the screen, they can make their own fraction pictures on the free printables that go with the activities.
3. Get the Games Out
Games serve more than one purpose. First, they make what could be a dry and boring topic to your students more fun and interesting. They also often provide that visual component that is especially helpful for some students. Here are a couple of my favorites:
Missing Numerator Game: For this game, the student needs to determine the missing numerator to determine how many spaces to move forward. Sometimes kids just need practice to build fluency with a particular skill. Games like this can make the required practice a little less painful.
Domino Fraction Games: There are two fun games on the Upper Elementary Snapshots website. Both of them involve drawing dominoes but using the two opposing sides of the dominoes as fractions. The possibilities here are endless: Compare fractions, add fractions, match fractions. Pick your favorite and dive in with your kids.
4. Turn to Tech
Another strategy I like to use to help kids build fluency with their fractions skills is to let them practice digitally. Apps and other online resources can help solidify concepts. Two apps that my kids particularly enjoy are Squeebles Fractions and Fractions. Smart Pirates. But you can find a giant list of websites and apps here.
Both apps present fractions visually and include fun games that ask students to be more flexible in their thinking about fractions, often helping correct misconceptions kids may have in place. For example, this activity from Squeebles Fractions helps students understand that serving ⅓ of a cake may still require two pieces, not just one.
5. Be Strategic in Teaching Fractions
When you’re introducing a new concept, free exploration with manipulatives and games can help students become ready to learn. But I’ve learned that when it comes time to teach a particularly challenging concept, it’s always helpful for me to map out my goals and objectives.
Step-by-step, strategic instruction can address all three of the larger issues listed above that students face when they’re struggling to learn fractions: limited understanding, misconceptions and lack of practice. If you feel like your math curriculum isn’t offering enough guidance, I love the free resources available through the TI Building Concepts program, which provide the kind of structure that helps guide students through what can be a tricky concept.
