Checking for an inequality sign as input

Questions
1

I want students to compare two fractions and input a less than or greater than sign as input and code for self check. Not sure how to code the solution part to check.

Unlabelled Note CL
content:"Use a greater than (>) or less than (<) sign to make the statements true;
\n(hint: compare fractions once they have a common denominator)
\n\frac{1}{2} \frac{3}{8}"

when input3.timeSinceSubmit>0
when input3.script.correct “Excellent!”
otherwise “Almost! Try again.”

Math Input CL (called input3)
correct = “>”
correct: correct

Maybe make a multiple choice question. This way they can see the statement change as well.

In the multiple choice component:

sign = when this.isSelected(1) "<"
       when this.isSelected(2) ">"
       otherwise "?"

Then, in your question:

content:"Use a greater than (>) or less than (<) sign to make the statements true;
\n(hint: compare fractions once they have a common denominator)
\n\frac{1}{2} ${yourMultipleChoiceName.script.sign} \frac{3}{8}"

Change your directions to “change the ?” or whatever to make more sense.

In the future if you want ≥ or ≤, use \ge or \le.

Thanks. I’ll give that a try.

Inequalities is something I wrestled with for a bit. This was the best I came up with. Here is a link to some example problems I use for domain and range. You can use this input code to go along with your evaluation.
