We do offer mouse training for students who need to practice those skills. You don't need an ST Math login to use mouse training. To start, go to play.stmath.com and click on the mouse icon in the footer.
That will launch a 3-5 minute activity that will evaluate the student's ability to control the mouse movement and successfully left click on objects. Once the student is done, they can keep practicing, and the teacher can double click to see an evaluation of the student's current ability on a scale of one to five, and may provide notes on specific issues.
