Today, we're going to explore how turn-around facts can make math easier and more fun!

📌 Key Talking Points:
  • Some addition facts are easier to remember when we know they work both ways
  • If 3+5 = 8, then 5+3 must also equal 8
  • This means we only need to learn HALF the addition facts!
💬 Discussion Questions:
  • Can you find some turn-around facts?
  • How does knowing turn-around facts help us?
3Activity: Turn-Around Treasure Hunt (12 min)
game

Students will play a matching game with turn-around facts

📝 Instructions:
  1. Spread out equation cards face down
  2. Take turns finding matching turn-around facts
  3. Use linking cubes to verify the sums
  4. Keep the pairs you match correctly
🔄 Variations:

Simpler: Use fewer cards with smaller numbers

Challenge: Add a timer or compete for most matches
