Learning to read using patterns makes things a bit easier. Rhyming is fun for kids, so using word families is useful. It is also key to phonemic awareness, which aids in reading success. Word families benefit some kids because they can see how the words in a particular family end the same. If a child can read hat, then he can easily learn to read cat, sat, bat, mat and so on.
You and your child can make word family charts. It is fun to make word family flowers too. Put the family, /at/, /an/, /ive/, /ent/ and so on in the middle of the flower and words in the family, /hat, pat, rat/, /can, ran, fan/, /jive, hive, live/, /spent, rent, lent/ on the petals.
