I find it a challenge to explain to students I am tutoring the concept of smallest and largest. I found that they must first under this concept of the single digits 0-9. I made this simple, vertical bar graph on one 8 1/2 by 11 inch page with each number having its own separate color on a lined table so it could be pictured as blocks on top of each other.
You have my permission to enlarge it if you wish.
I hope this can be of a use to you. Please leave feedback and follow me as I continue to add more items to my store.
