Say and notice
Say “The ship sailed away.” Say ship slowly: sh · i · p. In this word, the letters sh work together to represent one sound.
Write sh | i | p in three spaces. Count the four letters, then the three sounds. Do not add an extra spoken vowel after each consonant.
Cover, write and check
Look closely at ship, cover it, and write it from memory. Uncover the model and compare one part at a time. If “sip” was written, point to sh and say its sound together.
Try again once, then use the word in a sentence. Later, compare shop: the middle vowel changed, but sh stayed together.
