This is an interactive PowerPoint presentation with a Halloween theme that will help children go from using counters in one-to-one correspondence towards using tally marks and grouping them by 5. I used this as a "stop" during centers with my class because (using my Promethean board) I could leave the students without much guidance. They would take white boards and duplicate the marks on the board, first simple dots (counters) and then tally marks.
Once you purchase the presentation, you are welcome to edit or add-on as you like. Use this to meet the specific needs of your classroom!
