19 Free Printable Prefix Worksheets 4th Grade - Free PDF at ... - Free Printable

To solve this worksheet, we need to find the word in each sentence that starts with a prefix. A prefix is a group of letters added to the beginning of a word to change its meaning. Common prefixes include *pre-* (before), *re-* (again), *post-* (after), *auto-* (self), and *super-* (above/over).

Let’s go through each sentence one by one:

1. “I made sure to take the pre-test so I could pass my exam.”
→ “pre-” means before → “pre-test” = test taken before the real exam → ✔ pre-test

2. “When you play sports, it is important that you eat a pregame meal.”
→ “pre-” + “game” = before the game → ✔ pregame

3. “I had to re-do my test because I was absent.”
→ “re-” means again → “re-do” = do again → ✔ re-do

4. “I watched the postgame show on television.”
→ “post-” means after → “postgame” = after the game → ✔ postgame

5. “The car I bought was an automatic.”
→ “auto-” means self → “automatic” = works by itself → ✔ automatic

6. “I had to re-organize my backpack before coming back to school.”
→ “re-” = again → “re-organize” = organize again → ✔ re-organize

7. “We learned about the postmodern era in history class.”
→ “post-” = after → “postmodern” = after modern times → ✔ postmodern

8. “I rode my bicycle home from school with my friends.”
→ No prefix here! All words are base words. But wait — let’s check: “bicycle”? “bi-” is a prefix meaning two → “bicycle” = two wheels → ✔ bicycle

*(Note: Some might miss this — but “bi-” is a common prefix!)*

9. “The players went to a pre-game meal.”
→ “pre-” = before → “pre-game” = before the game → ✔ pre-game

10. “I had to regain my confidence in order to succeed.”
→ “re-” = again → “regain” = gain again → ✔ regain

11. “I went to the post-office to mail my letters.”
→ “post-” = related to mail or after → “post-office” = place for mailing → ✔ post-office

12. “I read a great autobiography by my favorite sports hero.”
→ “auto-” = self → “autobiography” = story written by oneself → ✔ autobiography

13. “My parents bought a new automobile this past Sunday.”
→ “auto-” = self → “automobile” = self-moving vehicle → ✔ automobile

14. “We went shopping for food at the supermarket.”
→ “super-” = above/large → “supermarket” = large market → ✔ supermarket

15. “The entire school had to wear the new uniforms.”
→ Wait — “uniforms”? “uni-” is a prefix meaning one → “uniform” = same form → ✔ uniforms

*(Note: “entire” has no prefix. “new” has no prefix. So “uniforms” is the only word with a prefix.)*
