Unit focus

  • Addition can join parts or find a total. Subtraction can take away or find a missing part. Strategies help students work efficiently and explain their thinking.
  • Use this routine: Read → Represent → Choose strategy → Calculate → Check.
  • Watch for using one strategy every time: Choose a strategy that fits the numbers.
