This one was a little more of an intangible, spatial concept lesson. I guess we were supposed to expand our vocabulary with the words up, through, and around using a batarang. I have to admit, that's a lot more fun than I ever had in English class.
Sadly, there is one other appearance of the Dynamic Duo on Sesame Street that I have only been able to hear of in legend. Batman and Robin caught the Penguin while teaching opposites, specifically using dirty and clean windows. If anyone could point me to that one I would be most grateful.
