Card sort feedback

I am trying to provide student facing feedback on a card sort. The cards should be sorted into 2 groups. A group of 5 and a group of 4. My dash board correctly displays a check or an x, but all of the student facing feedback that I have tried gives a false correct message to the student when student creates a group of 5 and 2 groups of 4. The attached activity includes the card sort and 3 attempts at feedback that give a false positive for a group of 5 and 2 groups of 4.

Try including mathesKey instead of just counting correctly matched cards. You probably get a false positive for splitting the group of 5 into 2 and 3 as well.

matchesKey works. It only give them binary feedback. (all correct or at least 1 card is incorrect)

After the fix:

For your feedback, use something like:

content: when matchesKey “100% whatever you want to say”
when k=1 “Looks like nothing is mismatched, but you should only have 2 groups”
when k=… etc.

What would k be defined as in your example?

k the way you originally defined it, but add a line at the beginning:

k=when whateverName.matchesKey 5

then switch your condition for your 100% correct meme to k=5. k=1 should be one of the keep trying memes.
