This document outlines a 4th grade mini-lesson on word study. The objectives are to use long-a letter patterns to read words, sort words by vowel sound, and participate in partner discussions respectfully. Students will underline words with the long-a sound in a passage, identify letter patterns that produce long-a, and create a word sort chart with categories for different long-a and short-a letter patterns. They will then apply this knowledge to better read another passage and this week's spelling words.
