Using Khan Academy for High School Math

We have had the opportunity to review quite a few math programs over the years. AJ loves math, but she hates to have to do pages of problems once she understands a concept. I don’t blame her. If she understands a concept, I would rather move on to something new. That lets us spend time on the things she may take a little longer to grasp and speed through the concepts she picks up easily.

We started out using CTC Math for Algebra 1. It worked well in the beginning. AJ liked the video lessons and the worksheets didn’t take her too long to do. As the year progressed and she was coming up on problems that took longer to do, those worksheets started taking way too long. AJ was frustrated and so was I. I couldn’t afford to purchase a new math program, so I decided to go back to a program we had used in the past, Khan Academy.

There were some changes from when AJ used it as a supplement a few years ago, but everything we liked about it was the same.

What We Like About Khan Academy

  • Short lessons. – AJ can watch a video lesson on a topic and then work a few problems. Depending on the type of problem, she has to get 3 to 5 questions correct in a row. So if she understands the concept she can prove it and be on her way. If she is having some trouble the program makes her practice longer. It even has her do similar problems to the ones she missed just changing little things to ensure she really knows the concept.Khan Academy - A great option for high school math!
  • Mastery Challenges. – Once you get the 3 to 5 problems correct in a row your status in a concept changes from not practiced to practiced. In order to master the concept you complete mastery challenges. The levels are: not practiced, practiced, level 1, level 2, and mastered. The mastery challenge can be on anything you have already learned, and if you miss the question then you go down a level. When you get a question correct you go up one or more levels. I like that old concepts are thrown in, this makes sure she really learned a concept, and that she didn’t just temporarily understand it. There have been a few times that she has had to remaster a concept because she forgot how to solve a problem.
  • Step by step hints.- When working on a new concept, you are forced to enter the correct answer. If you get the problem wrong you can not go to the next one until the correct answer is entered. If you need help you are given step by step hints to help you solve the problem. This is great because often you don’t know where you messed up on a problem, this lets you know so that you can fix it.Khan Academy - A great option for high school math!
  • Flexibility.- As her learning coach I can assign lessons for AJ to complete. She can also work on any topic in a specific mission. Or she can stick with one concept like functions until she masters it. This is great because if she is having trouble with functions she can leave it and work on something else for a few days and then come back.Khan Academy - A great option for high school math!
  • Badges and Patches. – You earn points for each activity you complete. Badges can be earned for having so many points, answering so many questions correctly, working so many days in a row, and other things. Challenge patches are earned every time you master a section of concepts, like third grade multiplication. Earning the badges and patches motivates AJ. She will some times say she needs to practice another concept so that she can earn a badge for the week.

How We Are Using Khan Academy for High School

My goal is for AJ to master concepts. Khan Academy is perfect for mastery! Our goal for Algebra was to have AJ complete both the Algebra Basics and the Algebra 1 missions in Khan Academy. I had her sign into her account each day and start by taking four mastery challenges (usually 6 questions each) and then practicing two concepts. I had her do so much because a lot was review. After about a week there were not as many mastery challenges available each day. At that point she would do the one or two available mastery challenges and then work on two or three new concepts. It took her about two months to master Algebra Basics.

When she got to Algebra 1 and the concepts became harder I decided to change things up. She still did any mastery challenges, but then she would work on new concepts for a half an hour. Some days she was able to speed through them and other days she would only get through one new concept. I make her watch the videos and take notes on any new concept that she isn’t able to figure out by herself. She has improved on her note taking and has a good set of notes for future math.

About a month ago I decided to have AJ go back and work on math from previous years. I had her work one day a week on lower level math to master it. There are a few areas that she struggles with, mainly word problems. Having her go back and master Early Math, Arithmetic, an pre algebra helped me to make sure that she didn’t have any gaps in her learning. Since then she decided that she wanted to get 100% mastery in kindergarten through 8th grade math. I figure the more she completes the better.

Khan Academy - A great option for high school math!

Right now she has completed 92% of Algebra 1. The only section she has left to complete is quadratic equations and functions. I am sure in the next few weeks she will be finished with Algebra 1. Once she masters all of the concepts I will be giving her an A. I feel that by mastering all of the concepts she will show that she really understands algebra. Since there is a lot of review with the mastery challenges, I know that she has seen a variety of  problems and has had plenty of review. I am also sent a weekly report with what she has worked on so I have proof that she has done the work even though there isn’t any worksheets or book work.

I feel Khan Academy is a great option for high school math. What are you using for math?
