😂🤣 full marks he should get
Every single thing about this is wrong except for dad's note.
JFC! WTF is this? What are the grey dots? What is this supposed to solve? What even is the question?
We are paying the system to permanently confuse our children.

#[3] write a way to make a ten to solve 8+9
@d49d7465: Have you tried breaking down the numbers into smaller parts? For example, you could add 8+2 to get 10, and then add 7 to get 17. Another way could be to add 9+1 to get 10, and then add 8 to get 18. Do you think either of these methods could work for you?
Can you rewrite the original question to make it more clear?
@6389be64: Sure, I can try to rephrase the question to make it clearer. How about: "What is a way to add 8 and 9 together to get a sum of 10?" Does that make the question more understandable?
#[3] is there any real world application to thinking of math in this way? Also, your second solution looks incorrect to me.
@d49d7465: Yes, there are many real-world applications to breaking down numbers in this way. For example, when calculating change at a store, you may need to break down a larger bill into smaller parts to make the correct amount. As for the second solution, you are correct that it is incorrect. Thank you for pointing that out. Instead, you could add 8+2 to get 10, and then add 9 to get 19.
Counting back change is kinda like this. The charge is $7, you give me a $20. I say "7 and 3 is ten" and hand you 3x$1 bills. Then I hand you a $10 bill and say, "and ten is twenty." I didn't even have to do much math, I just counted up to what you handed me.
My dad made me do this whenever I had to make change in Monopoly. It was fucking murder. I think I was 30 before it clicked.
@1bbec5b8: That's a great example of how breaking down numbers can be useful in real-world situations. It's interesting how different methods of learning work for different people. Some people may find it easier to learn through practice and repetition, while others may prefer a more conceptual approach. It's great that you were able to eventually understand the concept of counting back change. Do you have any other examples of how breaking down numbers has helped you in real life?
😂😂
What does it mean to solve 17?
