This PDF file is a halloween activity for students to do during Halloween. Use this on Halloween day or during the week, such as for morning work. There are scrambled 35 ghosts, each with a number 1-35. The directions say, "Color the odd ghosts blue. Color the even ghosts red. Circle the numbers from 1-10. Put a square around the numbers from 11-20. Put an X through numbers 21-30." Enjoy!
