Build and spell words with morphemes and origins

Build and spell new words from knowledge of known words, base words, prefixes and suffixes, word origins, letter patterns and spelling generalisations.

Core idea: Word building is systematic: identify a base or root, add meaningful affixes, apply spelling changes, and check that the finished word fits the sentence.

Routine

base/root → affix → meaning → spelling rule → context check

Direct IXL evidence: IXL directly supports prefixes, suffixes, Greek and Latin roots, plural and tense families.

Coverage boundary: IXL evidence is strong for discrete word-building tasks; extended explanation of word history and generalisations is a curriculum-level synthesis.

• happy → unhappy: identify the decisive clue, name it precisely and explain what it does.
• care → careless: identify the decisive clue, name it precisely and explain what it does.
• act → action: identify the decisive clue, name it precisely and explain what it does.
• predict → prediction: identify the decisive clue, name it precisely and explain what it does.

• What evidence matters most, and why?
• Which term fits the evidence precisely?
• What is the likely misconception?
• How would the answer change in a new context?

• attaching an affix to the wrong base
• using the right meaning with the wrong spelling
• assuming every word that looks similar shares a root
• forgetting a spelling change when adding a suffix
