Create Equivalent Fractions

- 4th Grade Math

In the third grade, children learned to identify equivalent fractions using visual models. In the 4th grade, they extend this understanding to formal methods, i.e., a/b is equivalent to (n x a) /(n x b). This equivalent fractions game focuses on identifying and generating fractions equivalent to a given fraction using the above method.


What’s inside?

- Fill in a missing numerator or denominator to make the fraction equivalent to a given fraction.

- Understand that equivalent fractions can be obtained by either multiplying or dividing both the numerator and denominator fractions with the same number.

- Create equivalent fractions to given fractions independently.


Real-World Application

When commenting on how many people turned in their science worksheets before the submission date, a teacher may use a fraction like 12/24 (12 out of 24). Or, she could also say that ½ of the students turned in the worksheets. The two fractions convey the same meaning and are equivalent.


What’s next?

The next skill that children pick up after mastering equivalent fractions is comparing fractions. Applying their understanding of equivalent fractions, they can now compare the magnitude of fractions with 1 and ½.


Cool Fact

To check if two fractions are equivalent or not, multiply the numerator of the first fraction with the denominator of the second and the numerator of the second with the denominator of the first. Is the product same? If yes, you have equivalent fractions.

4.NF.1Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
