Addition and Subtraction
OUTCOMES
A student:
› describes mathematical situations using everyday language, actions, materials and informal recordings MAe-1WM
› uses objects, actions, technology and/or trial and error to explore mathematical problems MAe-2WM
› uses concrete materials and/or pictorial representations to support conclusions MAe-3WM
› combines, separates and compares collections of objects, describes using everyday language, and records using informal methods MAe-5NA
