In this activity, students can compare what they could not do 100 days ago to what they can now do, on the 100th day of school. Students can cut and paste the rectangles onto a sheet of construction paper folded into fourths. Then, they can illustrate and write about what they could not do and what they can now do. I use this as a center, but you could also use it as seatwork and even as a writing activity. Included are two different versions, one with larger spacing for younger students and one with tighter spacing, for older students.
