Some “Big Ideas” (Essential Knowledge & Skills)

addressed in this lesson•Spelling makes sense and is primarily about meaning.•Words with connections in meaning often have connections in spelling that we can investigate.•The pronunciation of prefixes and suffixes can shift across words, but their representation in spelling is consistent to mark connections in meaning.•Words that sound the same but are not connected in meaning have different spellings where possible (homophone principle).•We don’t spell words with single letters, but with graphemes and morphemes. We announce these structural units orally and in writing in word sums.•Graphemes are one, or two- or three-letter teams that represent a single phonemes.
