📝 6. Open-Ended Questions
1. There are 11 birds on a tree branch. 4 birds fly away. How many birds are left on the branch? Show your work.
💡 Solution Steps:
To find out how many birds are left, we need to subtract the birds that flew away from the total number of birds. Start with 11 birds. Take away 4 birds. \(11 - 4 = 7\). There are 7 birds left on the branch.
2. Sam has 6 toy cars. His friend gives him 7 more toy cars. How many toy cars does Sam have now? Explain how you found your answer.
💡 Solution Steps:
To find the total number of toy cars Sam has, we need to add the cars he started with and the cars his friend gave him. We add \(6 + 7\). We can count on from 6: 7, 8, 9, 10, 11, 12, 13. So, Sam has 13 toy cars now.
3. Using the numbers 3, 8, and 11, write one addition problem and one subtraction problem.
💡 Solution Steps:
Addition problem: We can add 3 and 8 to get 11. So, \(3 + 8 = 11\).
Subtraction problem: We can start with the largest number, 11, and subtract one of the other numbers. If we subtract 3, we get 8. So, \(11 - 3 = 8\). (Another correct subtraction problem would be \(11 - 8 = 3\)).
