3rd Grade The Y-to-I Rule Worksheets
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.

How to teach this
Collect the endings this rule serves: -ed, -er, -est, -es, and -ness all trigger the swap; -ing never does, because criing would stack two i's. A quick why-not-criing conversation is the most memorable two minutes in this skill; kids love that English has a rule against double i.
Watch for: The change only happens after a consonant: cried and happier, but played and enjoyed keep the y. The y survives before -ing (crying, carrying) so the word avoids a double i.
Common questions about the y-to-i rule
- Why is it "crying" and not "criing"?
- English avoids double i, so the y holds its ground before -ing. The swap happens before -ed, -er, -est, and -es, but -ing is the standing exception. Kids remember it best as the no-double-i rule.
- How does this rule connect to plurals like "babies"?
- Same swap, different job: baby to babies uses consonant-y to -ies exactly as carry to carries does. We practice noun plurals on the plural noun rules worksheets and keep this page for verbs and comparing words, so each sheet stays one clean skill.
