Adding Fractions and Mixed Numbers

Mix things things up in your elementary math class with a series of problem-solving exercises. Presented with a series of mixed number word problems, young mathematicians are asked to solve them by using either visual fraction...

Here is a great video explaining multiplying a fraction by a whole number. Sal shows students how to put a whole number over 1 to multiply it by a fraction. He simplifies his answer and writes it as a mixed number.

This video on changing improper fractions to mixed numbers would nicely compliment the Khan Academy video on writing mixed numbers as improper fractions. Sal first shows students how to convert improper fractions. Then, he uses drawings...

Before Sal can divide a mixed number, he has to rewrite it as an improper fraction. He explains that dividing a fraction is the same as multiplying it by its reciprocal and that you can "cancel out" numbers to make multiplying easier.

This video shows how to write an improper fraction as a mixed number using drawings. Practice problems are available. [4:01]
