Change y to i and add a vowel suffix is a Grade 3 English worksheet that helps students apply spelling rules for base words ending in y. Across 17 items—13 multiple-choice questions and 4 drag-and-drop sentence items—students form words with -ed, -es, and -est, deciding when y changes to i, as in spy to spied, lady to ladies, and crazy to craziest, and when y stays, as in play to played. The worksheet moves from selecting correctly spelled words to using forms such as flies, ponies, tried, taffies, and candied in sentence contexts. This progression gives students practice recognizing the spelling pattern in isolation and applying it while completing meaningful sentences. It is a free printable worksheet with a complete answer key, suitable for Grade 3 spelling, grammar, independent practice, review, or a quick formative assessment.

This Grade 3 English worksheet focuses on spelling words that end in y when adding -ed, -es, or -est. Its 13 multiple-choice items and 4 drag-and-drop sentence items require students to change y to i in words such as spy, lady, and crazy, while recognizing exceptions such as play becoming played.
First, model a few base words from the worksheet and have students identify whether the y changes before adding -ed, -es, or -est. Then use the multiple-choice items to check the spelling pattern and follow with the drag-and-drop sentences so students apply forms such as flies, ponies, tried, and candied in context. Ask students to explain why play becomes played rather than plaied.
Students may keep the y when they should change it, producing forms such as ladys, fryes, or citys, or they may add an incorrect ending, such as spyed or tryed. In the drag-and-drop items, watch for students who choose a plausible-looking spelling without checking whether it fits the sentence, such as flyes instead of flies or ponyes instead of ponies. Also check that they notice when y stays in played.
