    Picking a trade school? (Cosmetology)

    Yes, I am a Debbie Downer, but I want to pass on this recent NY Times article about cosmetology schools in case it helps avoid some pitfalls.
  2. You and your student are doing great. Our pace was more like 1 section per day with 1-2 days on each on the end of chapter review and challenge problems. But we didn't do Alcumus, and they weren't self taught, they worked with me. I wouldn't sweat the proofs because the books contain plenty of those. The online class is fast-paced so he'll be moving along at faster than 2 days per section. I would say if he's comfortable with the current pace, then keep him there. One benefit of the online classes is your student may make some online friends in class. OTOH, the discussion forums are free, so he can always make connections outside of class. There is an active MathCounts discussion group he may find interesting. It's great that you are having him do old MCs. I agree with your observation that it gives him both review and preview. You can also try the AMC-8's which are available for free form the AoPS website. It's at about the same difficulty as the chapter level MC. If you want to bump up the difficulty, you can give your student the state or even national level MC or the AMC 10. But mostly, keep up the good work!

    Ivy League Interviews- What to Wear

    Ugh, my dd went to her MIT interview this month in jeans! (At least they weren't torn?)

    Misuse of the equals sign.

    I think the reason some moms on this board aren't poor notation at all is because they instill good habits at an early age. After a while it just doesn't make sense to write 3+8=11-2=9. It would like writing: I have 3 apples and he gave me 8 apples so then I had 9 apples. As long as we're on the subject of good notation, I'd like to add a couple of tips. (1) When combining like terms, I like to underline the terms that are being combined as I use them up, rather than crossing them out. My high school math teacher did this. I serves the same purpose of accounting for all the terms, but you can return to a previous line and more easily reread the terms if needed. (Bonus points if you underline the like terms in the same color, and distinguish them from other colors.) (2) If it isn't clear, I sometimes use notation (again courtesy of my high school math teacher) to indicate what I'm doing to an equation. For example, if I subtract 5 from both sides of an equation, on the next line I will write S5: (Capital S for subtract and subscript 5.) This is not standard, but I like using it. N+5 = 7 S5: N = 2 Although with beginning students I'll write N + 5 - 5 = 7 - 5 . And I will persist in doing this if I have even an inkling that this isn't clear.

    Misuse of the equals sign.

    Yeah, I don't know. Like I was asking way too much. "Do I have to?" It was like I was asking them to teach in sign language or something crazy.

    Misuse of the equals sign.

    I've heard this called Stream of Consciousness notation. If I see a student do this I will correct them. I was explaining this at our local homeschooling conference and I got some pushback from the moms there. I mean, I know it's a pain to write everything out, but it's also a pain to spell words out completely. KWIM? (get it?)
  7. The example you give is pretty nasty, and not the sort of problem you would see in AoPS for example. I only cite AoPS because it's one of the more challenging math curricula. Why are the easier math curricula so much harder than AoPS? (end of vent) Would it help if you scribed for her? Be sure to have her tell you where each digit goes and is able to explain why.

    Constantly having to log in

    Thank you for starting this thread. It wouldn't be so bad, except logging in seems to take forever, plus I'm not redirected to the page I wanted to visit. I go to some useless random page, and then need to back up a couple of pages, which also seems to take way too long.

  10. I'm sorry it's been some time since I had a syllabus approved, so I don't remember all the steps exactly. But I do know that if you select one of their sample syllabi, then approval is automatic. And after that, the CB will prompt you annually to renew your certification (they call it an audit) which only requires a few mouse clicks. Weirdly, in their agreement, you don't need to even follow the approved syllabus either. And you still get to call yourself a CB-approved AP class, which you can put on your transcript. (Homeschoolers make a big deal about what qualifies as being an official Advanced Placement course, but frankly, I don't see any CB police reading student transcripts.) Some people on this board have found the CB teacher discussion board to be useful, but I didn't make use of them. If you have trouble, copy/paste a screenshot here.
  11. If you haven't already, I would sign up to be an AP teacher and submit one of their sample syllabi for approval. Not only will you have a bunch of sample syllabi to work from, you will also have access to a lot of old exams for practice.

    Electrical engineering resources ?

    I second Make: Electronics and EEME. I can also recommend this Arduino book.
  13. Thank you for your detailed reply! This context is indeed very helpful and reassuring.
  14. Thank you for posting this and congratulations to you ds! I hope you don't mind my asking because my dd is applying to MIT. Unfortunately, she is nowhere near being an IMO competitor like you ds. I'm wondering if all the students attending are at our near IMO level, and if not, how are they managing to complete their problem sets? It seems to me that the social dynamic would favor all the best students working together, while students who weren't necessarily pure mathy applicants (maybe they were makers instead?) would be left to struggle.
  15. The Unbreakable Kimmy Schmidt is full of kind people. I wouldn't say the characters have above average intelligence, but the writing is very smart. The dialog is so fast paced that some folks watch each episode twice to catch everything.
