For introducing your students to adding and subtracting fractionsUse this Add and Subtract Fractions with the Same Denominator Worksheet to provide a clear introduction to this important mathematical topic. This adding and subtracting fractions worksheet features a series of questions, with two-segmented circles for each question. To work out the answer to each question, students must colour in the correct number of sections in the first circle, then colour in more sections or erase some sections according to the required calculation. When students know the answer, they can demonstrate it by colouring in the correct number of sections in the second circle. Great for visual learners, this adding and subtracting fractions worksheet has been designed to help children see how a fraction relates to a whole number. It also includes a useful answer sheet to help with marking and assessment. Suitable for Years 3 to 6. You could also try the Butterfly Method of Adding Fractions with your class.

What is the method for adding or subtracting fractions?When adding or subtracting fractions with the same lower number, or denominator, you need to add or subtract the two top numbers, or numerators, together, while keeping the denominators the same. For example, 3/8 + 2/8 = 3+2/8 = 5/8. Included in these worksheets are more examples, so refer to them if your little one wants to practise further. The above video may be from a third-party source.

Calculator UseAdd and subtract proper and improper fractions with this calculator and see the work involved in the solution. Select the number of fractions in your equation and then input numerators and denominators in the available fields. Click the Calculate button to solve the equation and show the work. You can add and subtract 3 fractions, 4 fractions, 5 fractions and up to 9 fractions at a time. How to Add and Subtract FractionsWhen the Denominators are the SameWhen fractions have the same denominators we simply add or subtract the numerators as indicated and place the result over the common denominator. If necessary we can simplify the fraction to lowest terms or a mixed number. When the Denominators are Unlike or DifferentWhen fractions have unlike denominators the first step is to find equivalent fractions so that all of the denominators are the same. We find the Least Common Denominator (LCD) then rewrite all fractions in the equation as equivalent fractions using the LCD as the denominator. When all denominators are alike, simply add or subtract the numerators and place the result over the common denominator. The resulting fraction can be simplified to lowest terms or written as a mixed number. How to Work With Negative FractionsWhen an equation calls for adding a negative fraction, we can rewrite the equation as subtracting a positive fraction. Likewise, if the equation calls for subtracting a negative fraction, this is the same as adding a positive fraction and can be rewritten this way. This calculator rewrites negative fractions when it shows the work involved in finding the answer.
