Sometimes kids need more than "sounding it out" to decode words in a story. Melissa Taylor has given us a handy tool in Word Attack Strategies. The one I use most is chunk it. Have the child cover the last part of the word with their finger and read the first part, if necessary then cover the first part of the word and read the last part and then blend.
