Big Idea
Development of computational fluency in addition and subtraction with numbers to 100 requires an understanding of place value.
Elaboration
  • Computational Fluency: Computational fluency develops from a strong sense of number.
  • Sample questions to support inquiry with students:
    • What is the relationship between addition and subtraction?
    • How can you use addition to help you subtract?
    • How does understanding 10 help us to add and subtract two-digit numbers?
