Two By Two

Dylan & I sat down to do a math lesson. It mainly focused on counting by twos. There were two vertical lines of dots down the page. This is how our conversation went:

Me: Okay, lets put our two fingers on these first two dots. When you lift up this finger, whisper 1 and when you lift up this other finger, say 2.

Dylan: (Whisper) 1, (Normal) 2

Me: Great! Let's go to the next set. Whisper 3, say 4.

Dylan: Mom, why don't we just say 2,4,6,8,10...18,20?

Math lesson over. Let's go play.
