Math tutoring in North Carolina

Kolu is software. Nobody from Kolu will drive to your house in North Carolina, and we have no office there. If you want a person, this page says how we would look for one. If the question is which skill is missing, we can help with that part.

North Carolina tests math with the EOG tests in grades 3 through 8. In high school, NC Math 1 and NC Math 3 each have a state exam (EOC tests), taken in whatever year the student takes the course. The main testing window is the final 10 instructional days of the school year, or the final 5 days of the semester for a semester-long EOC course.

A bad grade this year is often a gap from two years ago

A sixth grader who can't divide fractions has usually been taught the rule, flip and multiply, more than once. What's missing is older. They aren't sure that 2/4 and 1/2 are the same number, or their times tables are slow enough that every step costs them, and by the time they reach the new idea there is no attention left for it.

Going over tonight's worksheet gets tonight's worksheet done, and the same gap is waiting under next week's. The useful question is which earlier skill the mistakes point to. Answering it takes a different set of problems from the ones the class is doing.

Kolu finds the missing skill and goes back to it

Kolu's skill check walks backward from the student's grade until it finds ground that holds. Answers are checked by code, so an equivalent answer written a different way still counts and a sign error is recognized as a sign error. If the misses on fraction division look like an equivalence problem, the next session is equivalence, with pictures the student can drag. Fraction division comes back after that.

Kolu does not call a skill mastered after one right answer. That takes correct work on different kinds of problems on different days, and a skill that fades gets brought back.

Kolu is not test prep for the EOG tests. It has no bank of released questions. It teaches the skills the test draws on, and it will not do tonight's homework.

When to hire a person instead

Hire a person for math when the problem is not math. A student who knows the material and freezes on tests, or who decided in fourth grade that they are bad at this and stopped trying, needs someone in the room.

Ask the school first. Teachers know who tutors, and a counselor can tell you what the district already offers at no cost. A nearby college is the next place to look, since students there took these courses recently and usually charge less than an agency.

Whoever you hire, ask one question before the first session: how will you find out what my child doesn't know? If the answer is that they will go over the homework, keep looking.

Free for one subject, $15 a month for 5

Kolu is free for one subject at a time, with one full skill check every 30 days and up to 4 sessions a day. Plus is $15 a month, or $120 for a year, and covers 5 subjects at once with unlimited skill checks. A learner under 13 needs a parent or guardian to set up the account.
