Today we'll learn a magic math trick called 'Doubles Plus One'. When you see a number that's just one more than a double, you can solve it quickly!

📌 Key Talking Points:
  • Remember our doubles facts like 7+7=14
  • For 7+8, think: 7+7 is 14, then add one more
  • So 7+8 becomes 14+1, which is 15!
💬 Discussion Questions:
  • What doubles do you know?
  • Can you show me how to solve 6+7 using doubles?
