With its zig-zaggy lines, the letter Z can be a bit of a challenge for preschoolers to master. Our preschool letter Z worksheets help your little one conquer that challenge with exercises that require them to trace and then free-write the letter, both in its lowercase and uppercase forms. After the hard work is done, let them explore the last letter in the alphabet by coloring objects that have “Z” sounds, like zipper and zebra.
