Once students can read and spell closed, open, magic 'e', and r-controlled syllables, they are ready to learn about vowel teams and diphthongs. We teach the syllable types first because they open up many single and multisyllabic words for your students.
Most vowel teams are found in single syllable words. Vowel teams can be confusing because there are many letter combinations that can represent the same sound, so explicit instruction in vowel teams is essential.
Here's a reminder of where you are on our phonics continuum — what you have taught and what's coming up. This is not the only way to do things, and many programs will teach skills in a different order. That's okay, as long as students learn all the skills.
