When learning phonetics and the different phonetic sounds, your kids might find the entire thing a little confusing. First, they would need to learn and understand all the different sounds, and understand the short and long sounds as well. When it comes to vowel sounds, some sound alike. For example, the vowel digraph ou makes the same sound as the letters ow, as in cow. Read the words in this worksheet aloud to your students, and then help them check off the box next to the spelling of the word which matches the picture.
