A root word, or base word, is the main part of a word that can stand alone. When a prefix is added to the front, as in un-happy, or a suffix is added to the end, as in jump-ing, the root word is still there and still carries the main meaning. Spotting the root word helps a child work out new words: if you know happy, you can work out unhappy, and if you know help, you can work out helpful and helper.
This worksheet gives ten words that each have one prefix or one suffix, and the child circles the root word from three choices. The other choices are the added part and a shortened piece of the root. Ask your child to cover the beginning or the ending and see if what is left is a word on its own.
What your child will learn
Find the root word in a word with a prefix or suffix
Tell the added part from the root
Use the root to work out a new word
Common Core standard: L.2.4.C
Worked example
In unhappy, un- is the prefix and happy is the root word. Cover un and happy is still a word.
Common mistake
Circling the prefix or suffix because it is easy to see.
Helpful hint
Cover the beginning or the ending. What is left that is a word on its own?
