Lucky number 7! By now, you know several tricks. Let's use our combo tricks to take away 7 with ease.

Lesson 1

Concept

Subtracting 7 can be done by counting on, using 10, or breaking 7 apart! 🎯 **The "Break Apart" Strategy:** **Example: 15 - 7 = ?** 1. **Break the 7:** Let's break 7 into a 5 and a 2. 2. **Subtract the 5 first:** 15 - 5 = 10. (Easy!) 3. **Subtract the 2:** 10 - 2 = 8. So, **15 - 7 = 8**. 🎯 **Using the "Count On past 10" trick:** From 7 to 10 is 3 steps. From 10 to 15 is 5 steps. 3 steps + 5 steps = 8. Same answer! Use the strategy your brain likes best.
