Mixed Practice: All Word Parts

Congratulations! You've learned about roots, prefixes, and suffixes. Now let's put it all together with a mixed practice set that tests everything you've learned!

Quick Reference

Remember Your Word Parts!

Prefix (beginning) + Root (middle/main meaning) + Suffix (end) = Complete Word
