We have some fast Rocket Math students at our school. We want them to keep working and improving all the time. I want some students to start the skip counting function. What is the correction procedure while practicing? Do the checkers say the next number is ___, start over? Thank you.

Great question! There should have been some special directions in the Skip Counting Drawer for teachers. I fixed that this morning. Here's what I posted there.
How Students Should Practice SKIP COUNTING
Students should practice by saying the skip counting series in order from memory. They learn the harder series in parts, so they only have to say the part they are learning at that point. For example, in Set G students are to learn the first four numbers of the count by 9s which are 9, 18, 27, 36. When practicing in Set G, the checker says: "Count by 9s to 36." [That's exactly what it says on the little cloud at the base of the rocket, making it easy for the checker!] The student then says, "Nine, eighteen, twenty-seven, thirty-six." Of course, in Set H the student says the 9s to 63, and then in Set I all the way to 81.
CORRECTION: Each time an error or hesitation is made, the helper/checker should follow the following correction procedure. It is really important to do this correction procedure. The correction procedure is part of that "secret important stuff" that makes Rocket Math work.
1. Helper states the whole series up to that number, for example: "Nine, eighteen, twenty-seven, thirty six." (If the student has said the right answer but hesitated somewhere in the middle, the helper can confirm it by saying, "Yes, that was right, but you hesitated, so let's practice that some more. Nine, eighteen, twenty-seven, thirty-six."
2. After the helper says the series once, the helper and the student should say the series together twice. "Say it with me: Nine, eighteen, twenty-seven, thirty-six. And again, nine, eighteen, twenty-seven, thirty-six." Then have the student repeat the skip counting series three times.
3. Go back and do the previous series [just one, not three!], which is enough so this series comes up again before the student forgets it. (Rinse and repeat as necessary.)
