This assessment was designed to make sorting students into differentiated addition groups easy! It was originally created for my self-contained 3rd, 4th and 5th grade special education classroom, but will serve any teacher who is interested in identifying strengths and weaknesses of their students’ addition skills! It contains a pretest and post test with answer keys and includes the following skills: facts, rewriting from horizontal to column problems, column addition with and without regrouping, multi-digit addition, word problems, adding decimals, adding like fractions and adding unlike fractions. The results page included in the back of the packet will also aid you in grouping students into differentiated groups. Hit the ground running by placing kids into the right groups the first time with this assessment pack!
