Mastering the Make Ten Strategy
🎯 Making 10 is the most powerful addition strategy! Let's use ten frames to see how we can break apart numbers to make a ten, which makes any problem easier to solve.
Concept
"Make 10" is the secret to solving bigger addition problems quickly in your head. 🎯 **Why 10 is a Magic Number:** Our number system is based on 10, so adding any number to 10 is simple (10 + 4 = 14, 10 + 7 = 17). **Visualizing with a Ten Frame:** Let's solve **8 + 5 = ?** 1. **Start with the bigger number:** Put 8 dots in a ten frame. * [⚫️⚫️⚫️⚫️⚫️] * [⚫️⚫️⚫️⚪️⚪️] 2. **See how many are missing:** You can see there are **2** empty spots. So, 8 needs 2 to make 10. 3. **Break apart the other number:** Take the 5 and break it into **2** (to fill the ten frame) and **3** (what's leftover). 4. **Make the Ten:** Use the 2 to fill the ten frame. Now you have a full frame (10). 5. **Add the Leftovers:** You have 3 leftover dots. 6. **Solve:** 10 + 3 = 13. * So, **8 + 5 = 13**. This works for any numbers! Find the bigger number, see what it needs to get to 10, and break apart the smaller number.

Let's become masters of making ten! **Instructions:** Use the "Make Ten" strategy to solve these problems. Try drawing a ten frame to help! **Problem 1: 9 + 4 = ?** * How many more does 9 need to make 10? ___ * Break 4 into ___ and ___. * 10 + ___ = ___ **Problem 2: 7 + 6 = ?** * How many more does 7 need to make 10? ___ * Break 6 into ___ and ___. * 10 + ___ = ___ **Problem 3: 8 + 6 = ?** **Problem 4: 9 + 5 = ?** 🏆 **Challenge:** How would you use the Make Ten strategy to solve **9 + 8**? * Hint: 9 needs 1. Break 8 into 1 and 7. What is 10 + 7?
