Here is a fun way to reinforce vowels sounds and review spelling words. Provide each student with a xylophone. Using the power point lesson, students will play either the high "a" or low "a" depending upon the vowel sound. At the end of the practice, students will play, sing, and spell all the words on the spelling list.
Improvise: If you don't have access to xylophones, any small musical instruments would still be effective in assessing your students understanding of vowel sounds.
