Here comes that “magic e” again. This time it’s changing the short u sound to long u! 
Family Fun – Lesson 17
I can change vowel sounds in words by adding final e.
Objective: To change vowel sounds in words by adding the final e. (RF.K.3)
Materials: chalkboard, magic wand.
Procedures: Ask your child to spell “tub” on the chalkboard. Tell her to place the “magic e wand” at the end of the word. Explain that this word no longer says “tub” but by adding the “magic” e at the end of the word, the word has changed to “tube”. When there is a final e, the vowel says its real name. So the ŭ sound now says ū. Erase and continue with different cvc words, adding the final e.
Conclusion: Give your child five words to spell on lined paper that have long u and end with letter e.
