Check the "What order should my child learn phonics skills in?" section and have your child practice reading words with the letter sounds they already know. 

Once you know what letter sounds your child knows, go to the decodables page and have your child practice reading phonics based books from that section.  For example, if your child can read words from the Consonant Blends section, have them read stories from the Consonant Blends section on the decodables page.
