Lock and Key Matching Worksheet for Preschoolers
Matching each key to the lock sharing the same letter helps children ages 3-5 practice letter recognition in a playful, puzzle-like context rather than rote drilling. Because each key must be checked against several similar-looking locks before finding the right match, this worksheet also builds visual scanning and careful comparison skills that support problem-solving.

How to use this worksheet
Look at the row of locks together first, and say the letter printed on each one aloud. Pick up one key and identify its letter, then scan across the locks to find the one showing the exact same letter. Once your child spots the match, have them draw a line connecting the key to its lock, or color both the same color to show the pair. Continue until every key has been matched to its correct lock.
