What This Standard Means
What Students Need to Do
- Students apply spelling rules when they add endings to words. They write words like making and hopping correctly, then practice until they can spell them without stopping to work out each letter.
What Mastery Looks Like
- A student writes making, hopping, and looking from the base words make, hop, and look. They can explain why the e drops in making and the p doubles in hopping.
Common Misconceptions
- Some students write makeing because they keep the silent e. Others write hoping for hop plus ing, or lookking for look plus ing, because they do not check the base word's vowel pattern.
How to Assess It
- On an exit ticket, ask students to add ing to make, hop, and look. Have them explain one spelling change.
Lesson moves
Ways to Teach It
Give pairs letter tiles to build make, hop, and look, then add ing and move or add letters to spell each new word.
Ask, 'Why do we write hopping but hoping?' Have students name each base word and point to the letters that change.
Show bake, sit, and rain for a quick whiteboard round; students add ing, then check each spelling with a partner.
Have students write a recipe note using 'Bake the rolls' and 'Keep baking until brown,' then circle the spelling change.
