I am trying to create a question about solving systems of equation by elimination, but I want to be able to create a question that changes the values of the coefficients so that all my students get a different question to prevent cheating. I know I have to use the random generator, but I don’t know…

You can use the randomly generated variables to calculate the answers, and then use those answers to provide feedback when the students input their answers. I whipped up a quick activity that gives an example of this: [image] Linear Equations • Activity by Amplify Classroom by Andrew …

Great explanation using the randomGenerator(). One suggestion if using that approach would be to use an absolute value difference within a tolerance instead of a comparison of values for correctness in answer lines 4 and 5. For example: x_key = prompt.script.x_key is_x_correct = numericValue(`\ab…

Oooh, I was thinking about the tolerance but couldn’t think of a clean way to do it, that’s really nice! I was also wondering if it’d be possible to keep all answers integers, and that’s a really nice way to do it. Thanks! I have updated the activity linked above. The first page gives problems whe…

Thank you for sharing your ideas , I can’t wait to try them! I love learning and teaching but I always need more time. I really appreciate your help!

I have a quick follow up question. Does the rand.int change every time I move away from the screen then back, or does it change when I close the activity, then open it?

It will not change every time. Once it initializes it’s set, although anything in CL is individually randomized for each student (i.e. generally students will have unique values). randomGenerator() allows a seed argument, so you can use button presses or, say, correctness counts to reset values. r …

Thank you for your help, I did it! I modified it a little bit, but I did not know how to deal with the case when they get equivalent equations. My students were surprised when they saw that everyone got different questions! I really appreciate your help! Thank you! [image] Systems by Eli…

You could probably run a third set of values to use instead of the second when the first two sets match. I’m pretty sure I’ve seen a more robust way, but I’d have to track down a method.
