Hi!
I’m stuck and can’t figure out the CL to have the Table check the moveable points to be in the correct location. Here’s a screenshot:
In the graph, I added a check for each point in their folder, (A_C, B_C, C_C, D_C) which evaluates to 1 if each coordinate is correct, otherwise 0. Then, in the table CL, changed your isCorrect. (If you don’t copy this, you missed the capital C in your conditional statement using isCorrect1).
Perfect! Thank you!
Good catch on the capital letter inthe “isCorrect” too. 
I was hoping to see the CL in the example you shared here, but when I click on the activity link it says “Activity not found.” Is there a way to revive this? I’d really appreciate it! I am looking to use the same idea to check that students graphed the points correctly. Thank you!
Sorry, a lot of activities to manage and regularly clean them out.
Here’s a screenshot of a way to do that. An answer key list, a list of the points the student moves, a list of the differences between the coordinates, and then a total of the absolute values. So when C_heck=0, it’s correct.
Here to go- it’s screen 3 in this activity.
Thank you both so much! I appreciate your quick response on a WEEKEND! 
Wait, is there a way on the next screen to keep the names of each point in tact, as well? I’m using some of the same ideas that Munmath has on slides 3 & 4 that were shared. So like on slide 4, show the previous points plotted along with each of their names (A, B, etc)?
•For the screen in question, I used the following cl:
previous=graph1
background: graphLayer(previoius.calculatorState)
Not sure how to make it also copy the point labels. It only copies the polygon created when the 4 points are moved.
•Other suggestions? @cwinske @Daniel_Grubbs @JayChow
I haven’t had time to test this out, but would labelText work? Here is an example in the documentation.
It looks like graph sinks work in a sketch now, so you could have points, A-D, in your sketch graph with slider coordinates (or maybe a list for less CL code). Then, you can just label them in graph.
How’s this?
Perfect! Thank you so much!!
This is exactly what I needed today, thank you!
