How we explain it
Children can open this short lesson before they practice.
- Short vowel plus one consonant: double it before -ing or -ed (hop → hopping).
- Silent e: drop it before -ing (make → making).
- Consonant plus y: change y to i before -ed or -es (carry → carried).
Example: Add -ed to “carry.” Which spelling is correct? “Carry” ends in a consonant plus y. Change the y to i, then add -ed. Answer: carried
