    For some reason I am having difficulties with printing and posting the paper I completed. So I will try and type it all out:

    Adding 3 digit numbers

    1. Not knowing where to start. (Hundreds First)

    2.Students that are adding the ones first might run into the issue of not being able to regroup correctly.

    3. Adding and regrouping the ones correctly but not the tens place

    4. Adding and regrouping correctly 70% of the time

    5. Can solve the problem correctly most of the time and by using several different strategies, such as using standard form and expanded form.

    123 100+ 20+3

    345 300+ 40+5

    468 400+ 60+8=

    468
