What kids practice
Many longer words are built from a root plus a prefix or a suffix, like inspect, transportation and visible. A root is spelled the same way in every word, so learning it once helps with many words. A few rules cover what happens when parts are added: keep every letter when you add a prefix, drop a silent e or change y to i before some suffixes, and choose between endings like -able and -ible or -tion and -sion.
Watch for
- Dropping a letter when a prefix makes a double letter, like mispell for misspell.
- Keeping the silent e before a vowel suffix, like createion.
- Forgetting to change y to i, like happyness.
- Spelling a root the way it sounds instead of the way it's built, like microscop or autograf.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full spelling with roots guide for 4th grade.
