I just ran the Graph Paper Programming lesson with the new sheets. The students had no problems with the assessment, but the Activity Worksheet caused major issues.
Having the steps in a grid pattern greatly confused them and many hard a hard time (especially as 3rd graders) transitioning their brain to realize that it was just an ordered list of steps and NOT a grid for drawing.
On the assessment page, the steps are written out in two long rows that in no way resembles the grid they are drawing.
I think changing the activity to be more like the assessment would help a lot.
