Developing Essential Understanding of Addition and Subtraction for Teaching Math in PreK-Grade 2
What is the relationship between addition and subtraction? How do you know whether an algorithm will always work? Can you explain why order matters in subraction but not in addition or why it is false to assert that the sum of any two whole numbers is greater than either number? This title is organised around two big ideas, supported by smaller, more specific, interconnected ideas (essential understandings).
