  • Summary

  • What kinds of tasks help students build multi-digit addition and subtraction strategies? In this episode Pam and Kim discuss how to sequence tasks to develop the foundational strategies and relationships for multi-digit addition and subtraction: Friendly numbers, place value, adjusting, the commutative property, decomposing

    Talking Points:

    • Sequencing tasks is more than just moving from one page to the next in the teacher guide
    • Sample of three "messy" tasks to:
      • develop number lines
      • make connections between addition and subtraction
      • analyze strategies
      • solidify a strategy
