Spelling Pattern: -tion and -sion Endings

-tion and -sion appear in thousands of English words. Learning these patterns transforms seemingly impossible words into predictable, spellable units.

• Framework: Montessori
• Unit: Language
• Learning area: Word Study
• Level: Ages 5-6

Objectives

• Read and spell words with -tion and -sion endings
• Understand these suffixes change verbs to nouns
• Build morphological awareness
• Improve spelling of complex words

Materials

• -tion/-sion word cards (action, nation, addition, vision, decision)
• Base word to derived word matching cards
• Sorting mats

Instructions

1. Present: 'action.' 2. 'The ending -tion says /shun/.' 3. Practice reading -tion words: nation, addition, fraction. 4. Present: 'vision.' 5. '-sion also says /zhun/ or /shun/.' 6. Connect to base words: act → action, decide → decision. 7. Sort -tion vs -sion words.

Educator tip

Help children see that -tion/-sion often turns a verb into a noun: create → creation, divide → division. This is powerful vocabulary building.
