Quick Answer: Fraction Bar for School Maths Lab is a set of bars in which a whole bar and bars cut into equal parts, such as halves, thirds and quarters, are laid side by side. Pupils line up fraction bars under the whole to compare fractions by length and find equivalents.
Comparing Fractions by Length
A fraction bar set turns fractions into lengths that can be placed side by side. Stacked in rows beneath a whole bar, the pieces form a fraction wall: one row of halves, one of thirds, one of quarters and so on, depending on the set. Every row has the same total length, which reinforces the rule that fractions are only comparable when they are parts of the same whole.
The first surprise for many pupils is that one third is longer than one quarter, even though 4 is larger than 3. Laying the pieces together makes the reason obvious: the more equal parts a whole is cut into, the smaller each part becomes. Equivalence follows from the same wall. Two quarter pieces end exactly where one half ends, and three sixths reach the same point, so 1/2, 2/4 and 3/6 name the same length.
Addition begins with pieces of the same size. Placing one quarter and two quarters end to end gives three quarters, which shows why the denominators stay the same while the numerators are added. Continuing past the end of the whole bar, five quarters line up with one whole and one quarter, introducing improper fractions and mixed numbers without any rule to memorise.
Applications
- Building a fraction wall beneath a whole bar
- Comparing unit fractions and explaining why 1/3 is larger than 1/4
- Finding equivalent fractions by matching lengths
- Adding fractions with the same denominator end to end
- Converting between improper fractions and mixed numbers
Specifications
| Item | Set of fraction bars for desk work |
| Model | Length (linear) model of fractions |
| Topics | Comparison, equivalence, addition, mixed numbers |

Care & Handling
- Sort the bars back into rows after each lesson so every set is complete for the next class.
- Store them flat in a tray; a warped bar no longer matches its equivalents exactly.
- Wipe with a damp cloth if pupils have written on them with washable markers.
Why Choose LabEquip
Primary teachers usually order one set of desk bars for each pair or small group so every pupil handles the pieces. LabEquip lists them in Mathematics School Lab Products; for whole-class demonstrations the magnetic fraction bars work on the board. Send quantities through the contact page.
Frequently Asked Questions
Why is 1/3 bigger than 1/4?
When a whole is cut into more equal parts, each part is smaller. A third is one of three parts and a quarter is one of four, so the third is longer. Placing the two pieces side by side under the whole shows this directly.
How do the bars show equivalent fractions?
Pupils line up pieces from different rows under the whole. If two quarters end at exactly the same point as one half, the fractions are equal. The same check shows that 3/6 and 4/8 also equal 1/2.
How are fractions added with the bars?
Place pieces of the same size end to end and count them. One quarter and two quarters make three quarters. Pupils see that the size of the piece, the denominator, stays the same while the number of pieces is added.
How do the bars show mixed numbers?
Keep adding pieces past the end of the whole bar. Five quarter pieces reach one whole and one more quarter, so 5/4 is the same as one and one quarter.
How do desk fraction bars differ from magnetic ones?
Desk bars are for pupils to handle at their own tables, so every child builds and compares. Magnetic bars stick to a board, so the teacher can build a fraction wall that the whole class can see.
Which fractions are included in the set?
Sets usually run from a whole through halves, thirds and quarters to smaller parts, but confirm the denominators when you enquire. A set that includes sixths and eighths gives more equivalences to find.
