Understanding Fractions and Building Fraction Number Sense

If you’ve ever taught fractions, you know they can stop students in their tracks. Just when students are feeling confident with whole numbers, we ask them to think about halves, thirds, or fourths, and everything changes. Confusion sets in as some students start treating fractions like whole numbers, saying things like 1/2 + 1/3 = 2/5. They're using the logic that worked for whole numbers, and it's our job to help them see why fractions play by different rules. With the right mix of hands-on activities, hooks, and multiple representations, fractions can become a concept that students explore with curiosity and a deeper understanding.

Building Fraction Sense from the Ground Up

A strong foundation in fraction sense starts with addressing common misconceptions through visual models and discussion. Students may assume that bigger denominators mean bigger pieces, when in reality the opposite is true. Using visuals like fraction strips or side-by-side comparisons helps students see that as the denominators increase, the size of each piece decreases. Students may also see fractions as two separate numbers when they hear phrases like “the top number” and “the bottom number.” Part of our work is helping them understand that a fraction is a single value where the numerator and denominator work together to represent one quantity. When students build fractions with models, they start to see that the denominator represents the size of each piece and the numerator shows how many of those pieces make up the fraction. 

Unit fractions, fractions with a numerator of one, are the building blocks of fraction learning. When students see that 1/4 is one piece of four equal parts, they can extend this thinking to other fractions. Fractions like 3/4 or 5/8 are formed by joining unit fractions of the same size. Three 1/4 pieces make 3/4, and five 1/8 pieces make 5/8. Using concrete visuals can help students grasp fraction ideas more easily than abstract numbers alone. Activities such as folding sticky notes into equal parts or building fraction strips and labeling each piece as a unit fraction help students visualize an abstract idea in a concrete way.

After students develop an understanding of unit fractions, guide them to use multiple representations to make deeper connections. Fractions can show parts of a region, parts of a set, points on a number line, or even the area of a shape. Using fraction circles, pattern blocks, blank fraction tiles, and Cuisenaire rods helps students see how different models can represent the same fraction. For number lines, you can use a piece of masking tape on the floor labeled 0 and 1. Then, you can ask your students to “stand” at different fractions like 1/2 or 3/4. Pair students to model the same fraction in different ways. Comparing a number line to fraction circles helps students see that different representations can show the same value. These experiences turn fractions into something students can "see" and experience.

Building Fraction Understanding through Picture Books

Picture books have a way of making math come alive, and fractions are no exception. Titles such as The Hershey’s Milk Chocolate Fractions Book and Give Me Half! capture students' attention and show how math appears in everyday life. They provide a familiar context that helps fractions make sense and feel more meaningful. 

It's not just about reading the book; it's about how you use it in your teaching! After reading Give Me Half!, you can have your students act out their own scenarios of sharing snacks, cutting pizza, or dividing toys. Literature gives fractions a story. For the Milk Chocolate Fractions Book, use real chocolate bars (if possible) or paper "chocolate bars" to model fractions as the book is read. These experiences give fractions meaning that stays with students long after a worksheet is forgotten. 

Pairing literature with hands-on modeling is a winning combination. After a read-aloud, transition to a quick sticky note folding activity or a fraction grab bag. Students can pull small objects like beads, erasers, or cubes from a bag and identify what fraction of the set they hold. These quick transitions keep energy high and strengthen conceptual understanding.

Show, Just Don’t Tell: Fractions

To deepen understanding of fractions, try Show, Just Don’t Tell: Fractions. This activity encourages students to move beyond naming what they know and to show their understanding in different ways. This resource includes fraction cards, action boards, and recording sheets. Students draw a fraction card, roll a number cube, and use the action board to determine how to represent their fraction.

The action boards are designed to keep things fresh and varied. Your student will be asked to represent the fraction as part of a region, as part of a set, in words, on a number line, in a story problem, or even with manipulatives. The best part is that there’s no single “right” way to respond. This means every student has an entry point into the activity and can show what they know in a way that makes sense to them.

This resource works well in small groups, math centers, or even as a formative assessment. You can differentiate easily by giving certain groups fraction cards with smaller denominators while challenging others with twelfths. Your students will love the variety, and you'll love seeing deep thinking unfold.

What’s the Question? Fraction Task Cards

A fun way to help students think more flexibly about fractions is through Here’s the Answer… What’s the Question? Instead of giving students a problem and asking them to solve it, this activity flips the script. Students are given a fraction and then challenged to come up with questions or scenarios that match it. For example, if the fraction is 3/4, one student might write, “I ate three out of four pieces of pizza.” Another might say, “I ran three laps out of four around the gym.”

This reversal encourages students to think flexibly about fractions and understand how a single fraction can appear in various real-life situations. It builds creativity and reinforces understanding at the same time. Task cards make this activity easy to manage and can be used as a whole-group warm-up, a partner challenge, or a math center option.

The beauty of this activity is that it naturally differentiates to meet students where they are. Some students will stick to straightforward examples. Others will create more complex ones. Either way, they’re deepening their understanding of fractions and learning to communicate their mathematical thinking.

Cubing with Fractions

If you are looking for a way to differentiate and add variety to your fraction practice, try Cubing with Fractions. Cubing is a strategy where students roll a cube with different tasks on each face. For fractions, the tasks might ask your students to compare two fractions, create a story problem, draw a model, or explain a concept in words.

What makes cubing powerful is that you can tier the cubes based on readiness levels. One group of students might work with simpler denominators and tasks. Another group tackles more challenging fractions. Everyone is working on the same overall skill, but at a level that moves their learning forward.

Students enjoy the element of chance when they roll the cube. The activity promotes thinking, discussion, and connections across fraction concepts, making it ideal for review, assessment, or adding energy to a Friday math block.

Bringing It All Together 

Fractions can be a challenging topic in elementary math. Addressing misconceptions, introducing unit fractions as building blocks, and providing students with multiple ways to see and represent fractions help them think more flexibly about these concepts. Incorporating engaging hooks like picture books and hands-on activities makes fractions feel less abstract and supports deeper understanding.
