Problem Solving

To solve basic math operations — and more complicated ones down the road — kids need problem-solving skills and number sense. Number sense is the ability to understand what numbers mean, how they relate to one another and how they can be used in real-world situations. Eight-year-olds are working on adding and subtracting with more sophisticated strategies, like "counting on" from the higher number for addition, or base-10 facts to compose or decompose numbers. Two-digit addition and subtraction is being explored too.
