The course is too easy, many students are not so motivated, many of them see your math TA class as the ideal time to relax. You can deal with that by announce in class that in two weeks time there will be a take home test that they must submit within a day. So, if they haven't mastered solving systems of linear equation by that time (something that ten year old primary school children can learn to do), they're going to be in deep trouble. Also tell them that you're available for questions, extra exercise problems via email and on some hours of some days in your office that suits you best.

You should propose this to the instructor of the course, just tell him/her that most of your students are at F-level and they're not making progress and you see doing an intermediary test as a possible way out.
