💯 100th Day of School

Our 100th Day of School worksheets turn a theme kids already love into hands-on reading, writing, and puzzle practice. As children work through each page they meet themed vocabulary such as ten, add, sort, and zero — then use those words to solve clues, hunt for hidden letters, and describe what they see. It fits right into our Holidays & Occasions collection.

Every 100th Day of School printable is a ready-to-print PDF with a built-in answer key. The same 100th day of school theme is available for Pre-K through 5th grade in five formats — crossword puzzles, word searches, word scrambles, picture-writing pages, and an all-in-one printable pack — so you can match the challenge to each child and keep the theme fresh all year.
