The Y-to-I Rule Worksheets
Words ending in a consonant plus y trade the y for an i before most endings: cry, cried; happy, happier; carry, carries. Second graders apply the swap to everyday words and meet the contrast case, where a vowel before the y (play, enjoy) means no change at all.
By grade
What students need to know
When a word ends in a consonant plus y, the y changes to i before most endings: cry becomes cried, happy becomes happier. The one ending that never takes the swap is -ing: crying keeps its y.
This skill runs from 2nd grade through 3rd grade. Pick a grade above for level-matched sentences, teaching notes, and worksheets.
The Y-to-I Rule across the grades
2nd Grade
Words ending in a consonant plus y trade the y for an i before most endings: cry, cried; happy, happier; carry, carries. Second graders apply the swap to everyday words and meet the contrast case, where a vowel before the y (play, enjoy) means no change at all.
3rd Grade
Third graders run the rule automatically across -ed, -er, -est, and -es, and can say why played keeps its y while carried loses one. The -ing exception (crying, not criing) rounds out the system: English simply refuses a double i.
