Ppt - Adding And Subtracting Fractions With Unlike Denominators: Using The Area Model Powerpoint Presentation - Id:2609934 from www.slideserve.com
The second powerpoint then focuses on adding and subtracting when the denominator is different, modelling and working through a range of. The first one looks at being able to add and subtract when the denominator is the same, modelling and working through a range of questions. You just have to find what their denominators have in common.
Keep The Denominators The Same.
Begins with pictorial explanations and then moves onto formal method using equivalent fractions. Make equivalent fractions using the lcd. Add and subtract common fractions and mixed numbers with unlike denominators.
Adding And Subtracting Fractions With Unlike Denominators 2 7 + 1 8 7 7 8 8 23 56 = 16 56 + 7 56 A.
The first one looks at being able to add and subtract when the denominator is the same, modelling and working through a range of questions. Rewrite with a common denominator. Use this presentation to teach the steps for adding and subtracting fractions with unlike denominators.

Find The Least Common Denominator.
Find the lcd of the denominators of the fractions. Check to make sure your answer is in simplest form. To add or subtract fractions with unlike denominators:
½ + ¼ You Can Multiply 2 And 4 To Get 8, Which Is A Common Denominator.
