    Anyone else love Khan Academy?  Free math practice!

    He seems a bit wordy on the videos we’ve watched…  but my kids do seem to enjoy the practice on it.  And they have added “badges” that they can earn… spaced theme which is a bonus to my space loving son!  

    After you master an exercise (get at least 10 right in a row) it suggests other exercises….  My rules…. they have to select a suggested exercise (if it says they need to review something, they need to do that first…) – well it suggested “Angle Types” for my son….  so he watched the video, and has “mastered” it….    Not something he has worked on on anything else!

    I’m trying to figure out what is up with my daughter though…. She mastered “addition 1” right away, answering 41 right in a row.  She got one wrong then, so the next day… as she had her last question wrong… it said to review it.  Well, she hasn’t been able to get 10 right in a row…. she has earned a couple of badges (perseverance, and similarily named ones) for working at it for so long….  but sure can’t figure out how she had gotten 41 right in a row, and now can’t get 10 right in a row…  

    I don’t think I’d use this as our main math curriculum… but sure makes nice practice!  (another post coming on math curriculums…

    I don’t use Khan Academy. I just saw the post’s name and had to mention that all I can think about is the

    wonderful Star Trek movie: The Wrath of Khan.Laughing

    Not related though, I guess, huh?

    If it did have anything to do with the Star Trek movie, they’d probably call it The Wrath of Math. And then, my kids would probably run the other way from all things math, LOL!

    LOL…  He isn’t Genghis Khan either……  (hm… people think of a Star Trek reference instead of a History refernce…. hmmm)

    Actually it is a pretty cool site.  Originally he was tutoring a relative (neice?) long distance so he would make a video for her… then he developed it with the practice exercises, and just kept adding to it.   He did it all volunteer in spare time for ages…. then I think he quit his job and was living on savings….  but now he has goten donations from places like Microsoft/Bill Gate foundation etc.

    I mentioned my son’s math frustrations and my need for curriculum that works for him (and CHEAP, too, lol!) on another math thread.  I think I might try “watching” a couple of Khan Academy videos when he’s around to see how he reacts to them, then maybe I’ll see if he will try a couple before school starts again in a couple of months.

    I recall checking out Khan briefly during the past year, but I never actually used them with the kids. A couple of weeks ago, I was viewing a Professor B math video online, and my son said “No, way!”  I think he is burned out on math right now because it is so frustrating for him.

    Well, I can tell you right now the videos I’ve seen are wordy

    For addition 1, he draws circles to mean fruit for each of the numbers, and counts them to get the answer.   He also draws a little number line to show how to get the answer that way.

    Funny!

    Yes, coming from a major history buff like myself that’s bad-and the children have been reading Genghis Kahn and the Mongol Horde in these past few weeks! My only excuse is I was raised by a Trekkie mom and have a Trekkie-in-training 10 yr. old son, so the topic comes up frequently by him!

    In all seriousness, my dd has sensory dysfunction and math is frustrating to her, too. She uses Math Mammoth as her main math, with TT as  a back-up. I won’t buy TT again, at aleast at these lower levels. One-I can’t afford it and two, she doesn’t get enough mastery; not nearly enough practice in that program. She needs lots of review.

    I’ll check this out.

    Review and practice issues are a concern for me, too, regarding my nearly-12yo dd.  Having a learning disability, it’s not unexpected for him to be frustrated with some subjects and we work around this (read-alouds so he can hear the information, oral narrations because he has such difficulty with the physical act of writing, etc.), but he simply must practice and review in order to master math concepts.  He has been working on addition math facts for nearly two years now and hasn’t gotten very far.

    I’m not sure that the online practice offered by Khan Academy will work for him.  I may have to print of some of my own worksheets for him.  I don’t know if he has the patience to use the “scratch pad” they provide, but I’ll have to try it.  (I guess I have my doubts about that.)  I often ask him if he would like to use counters or some sort of manipulative to complete addition and subtraction problems, and he never wants to use them.

    When it comes to math, he’s certainly a puzzle to me.

    I just spent some time looking over this site and I can only say THANK YOU! Smile This is exactly what I have been looking for for my dd to use as drill to nail her multiplication tables, and for my ds who is starting algebra and has some ‘issues’ with his understanding of basic trig. This site has a bit of everything, I think it will do just great for filling in the gaps and reinforcing in a different way when something doesn’t click.

    Many thanks for posting it.

    Hi All,

    I am new to the forum but am glad to see so many posts on things that I am using. (Khan Academy and AAS)  Just wanted to give my 2 cents worth on Khan.  For us it is a gift.  Saxon wasn’t working, Fred was good but dd was discouraged by his use of huge numbers, TT is highly recommended by a friend but out of our budget. 

    Both of my children are caught up in math. It is still not their favorite subject but at least they are progressing without tears. The topic review is so helpful and I love the fact that the website saves record of work done (so I can record it), each child has a “Math map” that shows what area to focus on next. Although my son needs my guidance to not jump around, he did surprise me the other day by understanding something that was further down the line. My daughter has gotten to the point of needing to watch the videos for explanation, but we both feel that Sal does a good job. (not being an Algebra whiz, I am learning right along side her, but that is not a bad thing.)

    Khan Academy is a good fit for our home school, and being free, it certainly fits our budget as well!

    p.s. You can print 10 problems at a time. I use this feature for myself, copy each problem onto paper, work it, then enter the answer on the website.  Seems to go faster that way.  My children prefer to do one problem at a time.
