I have a card sort activity for quadratics that a student matched cards and it told them 20 out of 20 correct but it didn’t actually match the answer key.
Do you know where the error is?
That is strange. To avoid kids just randomly trying to match cards and
watching the __ out of __. I give limited feedback. See screen 3 of this activity.
It is saying you have matched 20 out of 20 cards correctly because technically they are with another card in the correct group. Notice that it doesn’t give the stars that what they have the groups that match the key until you put them together. I am not sure how to fix this.
I would take the other approach of sharing with them how many are incorrectly sort. This way, they know when they pair two they are not wrong. You can also create fun fireworks to appear on a following page.

As Tracy said, it says 0 incorrect because as long as any two of the four are paired correctly, they the number of incorrect cards goes down by 2. You can add a piece of code to the subtitle (eg) that gives a hint when they’re not quite there yet.
subtitle: when incorrect = 0 and not(Sort1.matchesKey)
"You have sorted the cards into correct groups, but does each group have 4 cards?"
otherwise
"You have ${incorrect} incorrect out of ${total} cards."
See the second slide and create two pairs – I removed all but one group so you can check the code without having to group all the cards.

Thank you very much you all for your insight and programming feedback it is very much appreciated. I found this an interesting quirk in the desmos programming.
I really like that extra feedback piece. Thank you
