This 3-week unit focuses on 24 root words that are commonly used in English. Roots are practiced and tested in the context of complete words so that students deal with them the way they would in contexts outside of school. The files are included as PDFs and also Word documents in case you'd like to tweak anything for your own class.
Classroom-tested over five years with my third grade classes, this vocabulary unit includes a front-and-back page to introduce the week's 8 roots in class and practice them at home. Another front-and-back page asks students to match the roots with their meanings and then choose the correct meaning of a new* word as used in a sentence. I recommend having the first part of the quiz checked before allowing students to move on to the second part. (*Quiz words are real words, but are not used on the classwork or homework ahead of time so that students have to consider the root's meaning to identify the new word.)
The 24 roots and meanings are:
log: study, word, speech
phon: sound, voice
the: God, god
trans: move, change
BONUS: 3 Spelling Lists and a combined Spelling-Vocabulary Practice Page!
This year I supplemented our Spelling curriculum (which was a few weeks too short anyway) by assigning 15 words + 2 bonus words each week, mostly culled from the classwork and homework practice pages.
**As of Jan 15, 2016, also includes an answer key!**
To see a bigger preview of what this vocabulary unit looks like, you can check out my free Prefixes unit. However, that unit was only made this past year so it's not as robust and fully tested as the Word Roots unit!
