The 3 “Rs”

The best way to learn this material: wRite

Write out the words/meanings Color-Code if possible

Repeat Do it again

Review Flashcards, writing, saying, etc.

• Colors used here:

• Prefix (blue)• Root (Purple)• Combining

Vowel (green)• Suffix (red)• Important words

(brown)

When studying flashcards Start with a few (3-6).

Pick 1-2 that are hard, 1-2 that are easy Repeat them till memorized.

Add a few more (2-3) unknown ones. Mix with original pile, repeat till

memorized. Repeat adding a few at a time till they

are all memorized.

**We will be doing flashcards daily!**

How to analyze a word

Begin at the END of the word Suffix

Next look at the BEGINNING of the word Word root (or sometimes prefix)

Next look at the combining vowel This will help you to break the word up

into its parts – “O” is the most common combining vowel.
