Ok, I am a bit confused about the internet simulator for this activity. The simulator shows the students ASCII, Decimal and Binary. ( I know each of these can be turned off.) Where is the challenge in understanding the mapping between the Decimal and/or Binary representations of the ASCII characters if these characters can be seen?

I also need a bit more explanation on how to incorporate the formatting protocol into this activity.

My students played with this activity yesterday and I plan to pick up with it again on our next class meeting.

Thanks!
