This organizer is great for showing the variety of ways for solving three digit addition equations! I have included a blank organizer, as well as an example. There are also mini versions of the organizer (4 per page AND 2 per page), which would be great for interactive math notebooks or math centers. You may also consider laminating the organizer for use in a math center or small group.
