My Take
First, I use this website for homework with my Algebra 1, 2-Year math students. Rather then asking them to complete problems out of the book, every single night, I mix up the format of the homework. The problems generated in the program are easy to customize to fit the exact material I am covering.
How I Use It
I use this website to create virtual worksheets that they can do at home or in the computer lab. They receive feedback on their work immediately, and better yet, I do not have to grade their homework or even collect it. When they get to class the next day I know who did their homework, and who did not. Every student has had the chance to look at the correct answers and explanation for the problems they missed. If they still want help, then like normal, I do problems on the board from last nights homework. It's slick, and parents see it as a positive. One other side note, I always give time in class for kids to start their homework, so on days when I use That Quiz for homework I have the kids work in small groups on a class assignment.
