“Do you know today is your cousin’s birthday?”
“How old is he?”

“And next month I will be six.”

“Yes, so how much older is he than you? How do you do that math?”
“Ten plus six?”

“No, that is not correct. It is not addition.”
“I don’t know.”

“Okay, let me put it this way. Your brother is ten, you are six. You need to find the difference between the two. What is the difference between ten and six?”
“Oh the difference between ten and six! Got it.”

“Tell me.”
“Ten is BIGGGGGGGG and six is small.”
