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.
