Celebrate 100 Days of school by calling to memory 100 of their favorite things that have happened in your classroom this year. This activity has 2 fill in worksheets that contain 50 rectangles each for students to fill in either with words or pictures of things that they have learned, seen, and done in class, or on class trips, this year! My students loved this resource. I put them in groups so that they can share their memories with friends as they work. You may want to use colored pencils to make it colorful. Also on this download is a sample of ideas that your students can add to their worksheets.
