Teacher Resources
Teaching Notes
Guide students to look for pairs of numbers that make ten first (e.g., 7+3=10) as this simplifies the addition process for the third number. Emphasize that the order of addition doesn't change the sum (associative property).
Vocabulary
Common Mistakes
- Forgetting to add all three numbers.
- Making simple addition errors when not grouping efficiently.
- Not recognizing pairs that sum to ten, leading to more complex mental calculations.
Differentiation
Discussion Questions
- What is a 'friendly ten'? How can finding a friendly ten help us add faster?
- If you change the order of the numbers you add, does the total change? Why or why not?
- Can you think of a real-life situation where you might need to add three numbers together?
Extension Activities
- Group numbers to add easily.
- Use manipulatives for practice.
