Fraction Arithmetic
The below QuickQuestion Interface © generates random sums to do with fractions.
Choose which of the four operations you would like to practise, or select Random to get a mixture of questions.
Decide whether the fractions should be Unitary, Proper, Mixed or Improper, and if you would like one of the two numbers to be a whole number.
Choose how the denominators should relate to each other, and finally the maximum size of the denominator.
You can type your answers into the box to check them. Layout is important, and you should type fractions using / (eg "1/2"). If the questions is given as a mixed number, then the answer should be given as a mixed number, typed with a space between the number part and the fraction part (eg "3 1/2").
There is a 10QQI version of this activity.

Ideas for Teachers
Working with fractions can often cause students anxiety. Use this activity at the beginning of a lesson to practise these invaluable skills. Start of easy with only unitary fractions, then add some complications. Or for the higher sets, throw them in the deep end with some mixed numbers. Need to simplify a bit more? Choose to have one of the numbers a whole number. Great for students to use at home too, to practise the skills they need, with instant feedback on whether they have it right or not.
