Teacher's field guide

What Students Need to Do: Students read common words in sentences and spell them in their own writing. They notice letters that are easy to miss, such as the l in could.
What Mastery Looks Like: A student reads because, could, and their without pausing over each letter. They spell these words correctly in a sentence and choose their or there to fit the meaning.
Common Misconceptions: Students may write becuz for because or cud for could. They may swap their and there because the words sound alike, or read a word correctly but misspell it later.
How to Assess It: Hand students a slip that says, 'Could you put their books over there?' Have them read it aloud, hide it, then write the sentence from dictation.

Lesson moves

Give pairs letter tiles to build because, could, and would; have them read each word, cover it, and rebuild it from memory.
Write 'Their books are over there' on the board; ask students which spelling shows ownership and which points to a place.
Play word bingo with because, could, would, their, and there; call words in sentences and have students read each marked word aloud.
Post a classroom sign reading 'Put your books over there'; ask students to read it, then write a new sign using their or there.
