Well…it’s time. It’s time for your students to learn how to add and subtract fractions. I can’t say it will be easy or that there won’t be tears. I can say that it will take you several days and you should be prepared.
Add & Subtract Fractions
You need to understand that there is adding and subtracting with like and unlike denominators.
If you need some awesome anchor charts for Adding & Subtracting Fractions check them out here! You can also check out the guided math units that I have in my TpT store.
How to add Fractions
With like denominators
- Add the numerators.
- Keep the denominator the same.
- Simplify/reduce
- If there are whole numbers- add those up
With unlike denominators
- Find the least common denominator of the fractions (LCD)
- Rewrite the problem with the common denominators.
- Simplify if you can.
- If there are any whole numbers- add those up as well.
