This is to figure out how many more 100s a student needs on their AR tests in order to meet their AR goal.
I often have students that have made so many low grades on their AR tests that they have dug themselves in a hole…..and NOW they (or their parents) want to know how to fix it.
I teach Reading. I am not a math teacher. It took me HOURS to figure up a formula to help me know how many more 100s they needed quicker than I was doing.
The original way I came up with is a little longer, but I include it just in case there’s a reason it worked first. I don’t think there is. The quicker way can usually be done mentally. Please email me with any questions.
