How can I program a slide to show the correct answer on a task once a student has submitted their answer?

Hi Jay, I tried using this and it looks something like this. correct = “t^{2}-3t” content: when correct and studentinput1.submitted “You got it right!” when studentinput1.submitted “You got it wrong.” otherwise “prompt” I says that theres a problem with string,boolean not boolean,boolean. Al…

Currently, your correct variable has been set to the string “t^{2}-3t”. You need to direct desmos to check the student answer against the correct answer. Best not to try to compare latex. Better practice is to check a few solutions to the function. Here’s a function, f, in terms of t from student in…

Thanks Dan! My problem is I am also having my students plug in x+h and simplify. Would this still work with that? and how to I define the original function in the computational layer?

Why don’t you (publish and) share your activity link? Easier to take a look than keep getting descriptions. The code I used didn’t define the function. I just chose solutions based on what you said was the original function (I was just pointing out “correct” was not correct based on what you said wa…

Here is the desmos I am working on. I am working on showing the message of if they are correct. I found a way to do it with the latex layer. If there is a better way I would love to know how to do it. The slides I am trying to do this on are 2,3,5, and 6 then on 27 and 28 I want to check if the…

I edited slides 2 and 3. Slide 5 you can try matching latex, but that can be fragile. The added equality makes evaluating impossible though. [image] Mark_Ruzbarsky: My problem is I am also having my students plug in x+h and simplify. I assume you mean for students to expand it. If not, you’d…

I now edited Slide 27 and replaced the link above.

ok slowly understanding. Now if I have a different function lets say f(x)=x^2-3x what would I have to change for that to check now?

Okay. I edited Slide 2 to reflect this (revisit the link above). Basically, I made a variable in the note CL where you can change your function. Used that to dynamically change the note content (notice myFunction). Then, in the input CL, changed to compare evaluations of f and g instead of a specif…

Ok got the my function and the check its doing. Now I am looking at slide 3 and doing it there. The actual answer should be x^2+2xh+h^2-3x-3h but even on the original way you fixed it, it did not check. Thanks again for all this help. Its really helping me understand the CL layer checks

I assume you mean for students to expand it. If not, you’d need to alter the countNumberUsage parts of the CL.
