Ep 251: Foundations for Multi-Digit Addition & Subtraction Strategies

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
