A fraction wheel can also be used as an angle estimator. It is easy to make and is a useful resource to add to your maths kit.
An interactive maths kit is really useful for oral maths activities, maths starter sessions or maths warm-up activities.
The fraction wheel is made with two overlapping and linked card circles which slide to show different size parts or angles.

• Draw and cut out two circles the same size (approx.10 -15cm diameter)
• Draw one line on the radius from the centre to the outer edge of each circle and cut along this line.
• Overlap the two circles through the cut radius lines.
That's it - you have your finished fraction wheel or angle estimator. Laminating the circles isn't a bad idea as they slide a little easier when using them.
