I am wondering what the rational is for removing the internet simulator from unit 1? I really liked how those lessons all flowed into the buildup of the creating the internet. I also had a much tougher time getting students to order their lists using only circle-square as compared to C-S-T from previous years. Finally I was sorry to see the number systems lesson removed. That is always a mind-blower for students.
Is anyone else having the same issues? What do you think? I am considering using the old units,
