Use these vowel sorts to accelerate your students' spelling of vowel patterns in single syllable words followed by sorts with multi-syllable words. This resource has 12 sorts that give students practice with the long vowel patterns, r-influenced vowel patterns, diphthongs, and ambiguous vowel patterns. Each pattern has a sort with single syllable words and a corresponding sort that includes the same vowel pattern in a multi-syllable word sort. This is perfect for intermediate grades that have students who need intervention work in below level spelling patterns, but also need exposed to grade level spelling patterns. These sorts can also be used to differentiate for younger students who are working at a higher spelling level.
