Buzz: Questions & Answers
I'm a math teacher with a limited knowledge of code. I've been trying to figure out what the commands are (if any) so that I could use variables to create a problem, then create solutions using the same variables. Example: I wanted to create a problem where students reduce fractions, so I set variables for numerator and denominator, set the range, and it worked for the question. How do I make it so my answers reflect different operations using those same variables? i.e. if my fraction was 2/8, is there a way for one of the answer choices to be the simplified fraction like 1/4? I figured using a command for greatest common factor and division (or something). I tried to use the "$eval", but are there any other command prompts that perform other operations? The examples in the help section are basic addition and subtraction. Or possibly a way to convert a decimal to a fraction? I'm stuck and this is probably the most basic thing I will try to do with variables. If there was a guide other than the "How do I use Assessment Editor" about how to program, code, or use variables like this, I would appreciate the help.
