A root word is a base word before we add any extra endings. When we look at a word like looking, the root word is look, and the ending is -ing. Spotting the root word helps us understand what a word means! For example, the root word in jumped is jump, and the root word in jumps is also jump.

Why Base Words Matter in 1st grade
Recognizing root words is a major milestone in early literacy. In first grade, children transition from reading simple, isolated words to decoding longer words with inflectional endings like -s, -ed, and -ing. Learning to separate the base word from its ending helps young readers decode unfamiliar words more quickly, improves spelling, and builds comprehension.
Tips for Practicing at Home and in Class
First graders learn best through active, playful practice. Here are a few ways to reinforce root words:
- Highlight the Ending: Write words like playing or cats on paper and have your child use a yellow highlighter to mark only the ending.
- Word Building: Use magnetic letters to build a base word (like walk), then add different suffixes to see how the word changes.
- Spot the Root: When reading bedtime stories, pause on words with endings and ask your child to point out the hidden base word.
