This center will practice four different forms of place value: Expanded, standard, picture, and word. Students simply spin to create up to a four digit number and then fill in the corresponding forms of that number.
You can create this center by putting it into a manila folder with a paper clip for the spinner. If you want, you can print two copies for the center, or create it with one side empty so that students can write out and think about their work.
You can also play this as a game with students to see who can create a number and show it in all four forms the quickest.
