In this Grade 1 English worksheet, first graders become word scientists by swapping one short vowel to create a brand new word. Nine fill-in prompts guide children to change the vowel in CVC words like hot, cat, pig, and bug, producing hit, cut, peg, and bag. A four-pair matching task reinforces the swap rule, showing how keeping the first and last letters while changing the middle vowel unlocks a whole new set of short vowel words.
