Math Anxiety? Try The Adder

Children typically get introduced to fractions in 3rd Grade and start adding fractions with like denominators in 4th Grade and then, in 5th Grade, they work on adding and subtracting fractions with different denominators.

This lesson on Adding Fractions includes examples showing how to add fractions. It includes adding fractions both with like and with unlike denominators.

Ensure your children can add fractions with the same denominator before tackling addition with different denominators.

They should also be able to convert the fraction to its simplest form.

A common denominator must be found when adding fractions that have different denominators. This is the most important (and probably the hardest) step in adding or subtracting fractions. A common denominator can always be found by multiplying the denominators.

Sometimes the product of the two denominators denominator will not
be the *lowest* common denominator. Finding the lowest common
denominator in such cases can be a trial and error exercise. Take the
highest denominator multiply it be 1, then by 2 ,then by 3 and so on.
Each time check to see if the other denominator(s) are also divisors
of the number.

It is good practice to finish by reducing the answer to its simplest form (lowest term) if it is not in that form already.

Be sure your child understands that an answer that is not in its simplest form is not necessarily wrong.

Use the worksheets below to practice adding fractions.

- Adding Fractions (same denominator) e.g. 4/7 + 2/7
- Adding Mixed Numbers (same denominator) e.g. 4 2/9 + 6 5/9
- Adding Fractions (different denominator) e.g. 2/3 + 1/4
- Adding Mixed Numbers (different denominator) e.g. 5 1/8 + 6 2/5
- Adding Fractions - Tenths & Hundredths e.g. 4/10 + 23/100

Use the fraction worksheet generator to get limitless adding fractions questions. The range of denominators can be set and mixed and whole numbers can be included too.

The equivalent fractions page will help when adding fractions with unlike denominators.
