Improper fraction is to make the fraction easier to read by making the numbers of the fraction smaller, but the value stays the same. This is done by dividing the numerator and the denominator with the same number and while both the numerator and denominator are still whole numbers. These worksheets contains a set of fractions that needs to be simplified. It is a good practice for the students. You as a teacher can set the range for the denominator. Which means to make it more difficult for the students. As a range you can type for example 2,3,4; which means you will have fractions where ther denominator will be 2, 3 or 4. You can also type 5-10, that means value 5,6,7,8,9 or 10 will be used for the denominator. To make it more easy you can choose 4 levels with a set of denominators. The levels are easy, medium, hard and extreme. When you click on these buttons, the values will be written in the range of the denominator and then you still have the option to make changes.
