Alphabet Coloring Pages - great idea for baby shower! Print all the letters on cardstock or heavier paper. Have guests color the pages anyway they like and sign a message for baby on the back. Have the pages laminated and bound into a keepsake book!
Classroom Behavior Chart: A giant 100 chart & as the whole class does something really well one student pulls out a popsicle stick and colors the number found on the stick. Once ten numbers in a row are colored in, a party is earned.
