September 18, 2013 Dear Family, This past week we have done some review of our basic addition and subtraction facts. This is a skill that should be secure by 4th grade as we really shift focus to multiplication and division. Attached are addition and subtraction fact triangles (you can certainly use any kind of flashcards/review websites). Please help your student review these skills at home. Please feel free to contact me if you have any questions Take care, Nicole Fox
