Interactive quiz on adding by making 10 for Grade 1

📚 Quick Study Guide

• 🍎 Making 10: The 'Make a 10' strategy helps simplify addition by rearranging numbers to form a group of 10.
• 🔢 Example: To solve $8 + 5$, think of 5 as $2 + 3$. Add the 2 to 8 to make 10. Then, add the remaining 3. So, $8 + 5 = 10 + 3 = 13$.
• 💡 Why it Works: It's easier to add to 10 than to other numbers! It helps build number sense.
• ➕ The Formula: $a + b = a + (10 - a) + (b - (10 - a))$
