Write letters like "a" and letter sounds like "th" and "sh" on index cards with your pen or marker. Focus on sounds that are difficult for your child to pronounce.
Show the cards and say the sounds with your child. Be calm and patient; encourage your child with positive comments about her progress.
Take the cards with you on a "sounds" walk. This walk can be inside or outside. Point out objects that use the sounds you have specified on the cards. Ask your child to say the sounds with you.
Hold up each card and ask your child to point out objects she thinks contain that sound. Make it an enjoyable, engaging game, and patiently work with her on correct pronunciation.
Make a list of five to ten words or sounds your child has difficulty pronouncing. Many prereading curricula use sight words --- words that cannot be sounded out --- to begin teaching children to read; using sight words may be good to focus on both prereading and articulation.
Write each word on an index card with your pen or marker.
Lay the cards face down, blank side up, on either a table or the floor. Arrange the cards in random order in even columns and rows.
Instruct your child to turn over the card and say the sight word. On a separate index card, make a mark each time she answers correctly. Give your child another mark if she can use the word properly in a sentence.
Reward your child with an educational or learning activity when she successfully reaches a specified number (decided on by you, depending on your estimate of her skills) of tally marks or completes the activity for all the cards. Suggested rewards include going on a trip to the library for story time, picking out a new book at the book store or having an extra book read to her at bed time/nap time.
