This is a product I created for my students that struggled with the steps of adding and subtracting numbers with and without regrouping. Scaffold's are present to help with the early stages of learning the steps for the standard algorithm. Added are some fun Thanksgiving themed pictures for students to color when they have completed the problems. Total of 9 worksheet pages and one cover page. Plenty of practice for students.
