Quick Answer: Fraction Disc with Magnetic Board for School Maths Lab is a set of circles cut into equal sectors, supplied with a magnetic board on which the pieces are arranged. The fraction disc shows each fraction as a share of one round whole, which suits comparing and adding fractions and introducing pie charts.
A Round Whole and Its Parts
A circle is a strong model for fractions because the whole is unmistakable: a complete disc. When a disc is cut into four equal sectors, each piece is plainly one of four equal shares. Pupils assemble whole circles from pieces of the same size, then mix sizes to see which combinations complete a circle, for example one half, one quarter and two eighths.
The board keeps a model in place while it is being discussed. Pieces can be arranged, left on the board while the class writes the matching fraction statement, and then rearranged without the layout sliding apart. A board also lets a pupil work at a desk and then hold up the result for the teacher to see.
Circle fractions connect to later topics. Each sector has an angle at the centre, and fractions of a full turn become degrees: one quarter of a disc makes a right angle. That is the same calculation used to draw pie charts, so pupils who have handled these sectors find pie charts far less abstract.
Applications
- Building whole circles from equal sectors
- Comparing fractions such as 3/8 and 1/2 by overlaying sectors
- Adding fractions like 1/2 + 1/4 by placing sectors together
- Linking sectors to angles at the centre and to pie charts
Specifications
| Item | Fraction discs cut into equal sectors |
| Supplied with | Magnetic board, as named in the listing |
| Model | Circular (area) model of fractions |
| Topics | Part and whole, comparison, addition, angles, pie charts |
| Fraction divisions and board size | Confirm at enquiry |
Care & Handling
- Keep the sectors from each circle together in their own bag or compartment.
- Wipe the magnetic board with a dry cloth; water can rust exposed steel edges.
- Do not drop the board on a corner; a bent board no longer holds pieces flat.
Why Choose LabEquip
Primary teachers who want each group to have its own board and pieces are the usual buyers. LabEquip lists this set in the Mathematics School Lab Products range; if your classrooms already have magnetic boards, the EVA foam Fraction Wheel is the alternative.

Frequently Asked Questions
Why use a circle model for fractions?
A circle makes the whole very clear, because the pieces either complete the disc or they do not. It is easy to see that a sector is one of a number of equal shares, and comparing sector sizes is quick.
What is the magnetic board for?
It holds the pieces in place so a model does not slide apart while pupils write about it or show it to the class. Pieces can be rearranged quickly without having to be rebuilt from scratch.
How is 1/2 + 1/4 shown with the discs?
Place a half sector and a quarter sector together on the board. They fill three of the four quarter spaces in a circle, so the total is three quarters.
How do fraction discs connect to pie charts?
Each sector has an angle at the centre equal to the fraction of 360 degrees. A quarter sector makes 90 degrees. Pie charts use exactly this calculation to turn each share of the data into a sector.
How is this set different from the EVA foam fraction wheel?
This listing includes a magnetic board with the disc pieces. The fraction wheel is made of EVA foam and is magnetic, but its title does not mention a board, so it is used on a board the classroom already has.
Which fraction divisions are included?
The title does not list them, so confirm the divisions when you enquire. Sets commonly go from halves to eighths or beyond; including thirds and sixths makes more comparisons possible.
