Many adults seem to forget how difficult and time consuming it was to learn the multiplication facts. Research says the best way to remember is by using visual images and stories. It really can be FUN! What I enjoy most about the Premium Learning System is that it allows me to monitor student progress in real time. Students enjoy it because, with Zippy as a guide and games to entertain them, the program feels more like playing than working.

Because I want you to be good at math. And that takes practice. It feels good to get better at something. Do you feel like you are getting better at math?
If you make a mistake or cannot figure out the answer I will show you the right answer so you can type it in. If you see a green checkmark it means you got that answer right!
If you see a red x it means you got that answer wrong. If you see a blue hourglass it means time ran out on that question. The best thing to get is a smiley face. It means you got that answer right and did it quickly. With practice you will be able to get smiley faces every time. Just do your best and everything will be OK.
We will start with the easiest problems first. Go as fast as you can but not so fast that you make mistakes. We are going to have to do one or two more subtraction quizzes to finish the subtraction placement test.
This will be very similar to the last quiz. We are going to have to do one or two more multiplication quizzes to finish the multiplication placement test. Do you think you are ready for division? We are going to have to do one or two more division quizzes to finish the division placement test. But I suspect you knew that already! But first, look at this matrix of problems.
Some of the squares are colored. A gray square means we are going to practice that problem. A yellow square means you are pretty good at that problem. A green square means you are really good at that problem. This is also your chance to change the colored squares on your matrix to yellow and green.
You might be able to change only one or two squares to green today. But if you do XtraMath regularly then you can turn all of the squares to green. You can do it if you try hard! I know you can. For each problem you try to answer it before I do. Do you want to know the secret to answering the questions before I do? Questions come back over and over again so try to remember the answer rather than figuring it out. Try it this time! If I answer the question before you do then repeat the question and answer to yourself in your head a couple of times before you type it in.
That will help you remember the answer when the problem comes back. You finished another practice! Do you think you are getting better at these problems?
Try to beat me to the answer as often as you can. The secret is to recall the answer if you can. Otherwise, you have to figure it out, which can take a long time. In extra sessions we will do more practicing. I want you to know, though, that it is more important for you to do XtraMath every day than it is for you to do XtraMath many times in one day.
When you are taking the quiz try to remember the answers. When this happens I will show you the right answer. You will get to practice this problem and show that you know the right answer in the future. Type in the right answer to move on to the next question. And it will take you much longer to reach your goal of mastering all these facts. But it is really important for you to learn these math facts. You will use them many times in the rest of your math classes and for the rest of your life!
It appears that you are typing in wrong answers on purpose again. I sent a note in e-mail to your teacher and parent letting them know. I will show you a problem and you type in the answer as quickly as you can. But now you know how quizzes work in XtraMath. About the student activities. About the progress reports.

Learn about the mastery score and mastery matrix.
A program also specifies a threshold and a problem set for its operations. After placement, the student takes a progress quiz as the first activity of the first session of the day. A session begins when a student signs in, and is considered complete once the student has finished all activities and signed out.
Correct answers within the threshold get a smiley face. Correct answers beyond the threshold get a green checkmark. In alternative programs the threshold can be increased to six seconds, or decreased to two or one and a half seconds.
Upon timeout, the answer is shown with an hourglass icon. The student must enter the answer to continue on to the next problem.

Is it possible to have my student practice more than one operation — like addition and subtraction — in the same activity?
My child is struggling with XtraMath. Here is what you can tell your child if they are struggling with XtraMath: XtraMath takes only a few minutes each day, but it requires your undivided attention during that time. Stay focused on the problems and do your best every time. Accuracy is more important than speed — but once you do know the answer, type it in promptly.
You will have many more chances to answer that same problem in the future. Try to remember the answer first, and if you cannot remember it, then calculate it. Never enter wrong answers on purpose. If you do, your score will drop significantly and it will take you several sessions to prove what you already know and get back to where you should be.
It can take a long time to master an operation, so be patient and be persistent. Do XtraMath as regularly as possible while following this advice and you will make good progress. XtraMath goes too fast for my child. Most students become comfortable with typing numbers after only a few sessions of XtraMath, but if typing speed is a problem, have the student practice number typing prior to using XtraMath. A web search will turn up many number typing games.
For some students, a touch screen may work better than a keyboard or mouse. Another option is for the student to say the answer aloud, and an adult or older child to type it in on their behalf. Also, see our tips for struggling students. Can I reposition the keypad for a left-handed student? What reports on student performance are available?
