The issue I had with in the EPGY course my DD did was that it was not always clear (even to me) from the problem on the screen what was supposed to go in the empty box. It wasn't getting the answer that was the issue, but that they had a particular (but not yet taught) desired intermediate step, and the empty boxes were in the intermediate step.
Yes, I noticed that- in the 2nd grade level the only things DD had consistent trouble with were problems like this:
Mary and Sue have twelve dolls together. Mary has four more dolls than Sue. How many dolls does Sue have?Except they weren't just asking for the answer that Sue has 4 dolls. There were a bunch of empty boxes and plus and equals signs. So what they wanted was actually for the student to set up two equations using M and S as the variables.
m + s = 12
m = s + 4
I imagine that was probably in the lecture or examples, but I only came in when DD called and couldn't find a way to re-play it and ended up getting confused myself.
