How to Teach Fractions with Visual Models in Grades 4–5
How to Teach Fractions with Visual Models in Grades 4–5
Fractions make sense to students when they can see the whole, count the equal parts and say what each number means. This unit teaches fractions through drawn and shaded models in five paths: wholes and equal parts, numerator and denominator, comparing fractions, fractions in daily life and fair sharing. It is a 27-page student book plus a 14-page teacher guide with answer guidance, written for Grades 4–5.

The teaching problem
Why students read 3/4 as two separate numbers
Fractions are often the first place where number sense stops matching what students know about whole numbers. A student sees 3 and 4 and treats them as two counts that happen to sit on either side of a line.
The mistakes follow from that. Students decide that 1/8 is bigger than 1/4 because 8 is bigger than 4. They shade four unequal pieces of a circle and call each one a fourth. They say half of something without saying half of what, so half a liter and half a cake end up as the same amount.
Worksheets that start with symbols make this worse, because the symbols have no meaning yet. Students follow a procedure and cannot tell when the answer is unreasonable.
This unit puts the picture first. Students draw a circle cut into four equal parts and another cut into four unequal parts, and explain why only one shows fourths. Later they shade fractions in rectangles, compare strips of the same length and share loaves among children. The symbols arrive as a way to record what students can already see, and the teacher guide asks for reasons at every step, which a correct shading alone cannot show.
A sequence that works
A five-path sequence for fractions with visual models
Each path runs about one lesson: a short explanation with a worked example, an illustration to examine, Task A to practice alone, and Task B to explain a new situation. Plan 5 to 8 lessons in total.
- Wholes and equal partsA pizza cut into four equal pieces gives one fourth. Task A: draw two circles, one in four equal parts and one in four unequal parts, and say which one shows fourths.
- Numerator and denominatorThe denominator tells how many equal parts make the whole, and the numerator counts the selected parts. Students shade 2/3 and 3/5 in rectangles and explain what each number means.
- Compare fractionsWith the same denominator, more shaded parts mean a greater fraction. For different denominators students use strips of the same length to order 1/2, 1/4 and 3/4.
- Fractions in daily lifeHalf an hour is 30 minutes. Students find three situations with a half or a quarter and always state what the whole is, such as a cake, an hour or a liter.
- Share fairlyTwo halves of a rectangle can look different and still be equal. Task A: plan how three children can share two identical loaves so everyone gets the same amount.
Where it goes wrong
Misconceptions to plan for
A bigger denominator means a bigger fraction. Put 1/8 and 1/4 on strips of the same length and let students see which piece is longer. The book builds this in Path 3 before any rule is stated.
Any parts count as fourths. The parts must be equal in size. The unequal circle in Path 1 is there so students can say why it fails.
The whole does not need naming. Half an hour and half a liter are different quantities. Path 4 asks students to decide what the whole is every time.
Equal means identical in shape. Path 5 shows two halves of a rectangle that look different. Students justify equality by area, not by appearance.
Comparing needs a trick. With different denominators, the wholes have to be the same size before the comparison means anything. The unit uses equal-length strips for this reason.
Task B in each path asks students what the example does not show, and that question often surfaces the idea a student is still holding.

Frequently asked questions
Is this aligned to Common Core or the National Curriculum?
The content sits closest to the fractions work in the Common Core Number and Operations: Fractions domain in Grades 3 to 5, for example 3.NF.A.1 on unit fractions and 4.NF.A.2 on comparing fractions. It also sits near the fractions content in the National Curriculum in England and the Australian Curriculum v9. TeachLessons is not affiliated with the Common Core State Standards Initiative, and the unit is not endorsed or approved by it or by any state.
Does this unit teach adding and subtracting fractions?
No. It builds the understanding that comes before operations: what a fraction is, what the two numbers mean, how to compare fractions and how to share fairly. Students who can explain these ideas with a model are better prepared for operations. Use your regular program or a separate resource for adding, subtracting and multiplying. The teacher guide keeps its focus on explanations and sample answers for those ideas.
How do I differentiate?
Every path has a method page with two routes. For support, offer sentence starters, word cards and a shared description of the illustration, and let students work with pre-cut strips. To extend, ask students to test a borderline case, find a counterexample or compare two ways to share the loaves. A help card in the book is for students who are stuck. Oral answers and symbol cards are listed as accessible options.
How long does it take?
About 5 to 8 lessons. Each path suggests a 35-minute lesson: 5 minutes to open, 20 to explore and practice, 10 to consolidate. The paths also work separately, so you can use only Compare fractions or Share fairly if that is the gap in your class. The learning check at the end asks for a one-sentence explanation and an example for each path.
What do students produce at the end?
Students choose one path and create an explanation for another student with a heading, two examples and a question of their own. The teacher guide gives five criteria: accurate terms, well-explained examples, a meaningful question, a readable layout and useful image, and feedback applied. A learning check and a self-assessment page support feedback. The guide recommends self-assessment for feedback rather than a grade.
