    S/O White Washing Thread

    I was so confused when I scrolled over this topic & found discussion of washing machines. Then I realized I'm posting in the wrong decade. *whistles innocently*
  2. 1. Glad I couldn't figure out how to post pics lately. 2. I've reported myself & then figured out how to remove the thing that was probably not even a problem, thereby clogging up the reporting box. :/ So sorry. 3. Also--sorry this is a problem. :(

    Graphing Question

    Ok, sorry--after reading the linked site, I'm still not sure I understand well enough. The question in the math book is: "The distance required to stop your car depends on how fast you are going when you apply the brakes." The student is supposed to sketch a "reasonable" graph. Ds sketched a straight line; the book has the shape that belongs more to a "power function." He made this mistake on several of the Reasonable Graph problems (I hate the ones that don't have more definitive answers!), so I figured there was a...Reason of some sort.

    Graphing Question

    Thanks! I suspected that it had something to do w/ linear equations vs. ??? The set of questions ds was dealing with were more theoretical than solve an actual equation, so I figured there had to be a rule of thumb, but I couldn't figure out how to phrase the question for Google.
  5. Is there a "rule" or something to tell when you should graph something as a straight line vs when it should be a...I don't know what to call it...half of a parabola? For ex, when graphing a speed (time/distance) problem, will the result always be a half-parabola? TIA!
  6. Thank you so much, guys. I've just been so nervous about teaching this level--partly because Geometry was MUCH harder (for me) than I'd expected it to be. I've been doing a lot of second-guessing. I think this experience has given me the confidence to keep googling when I'm not certain about the SM & the other things I did. (Have ds explain his answer, do some others to make sure he's got the concept, etc.)
  7. Right, but these were like...the graph of a yo-yo or...ack. He never puts his book away, but tonight? 27. The rate at which you are breathing depends on how long it has been since you finished running a race. 30. The amt of postage you must put on a first class letter depends on the weight of a letter. 32. You plant an acorn. The height of the resulting oak tree depends on the number of years that have elapsed since the planting. So if I had read the questions, I would have had a better idea of the rightness (reasonableness) of his answers, & I didn't do that until just now. But his answers...if it had height on the y axis & speed on the x, he did the opposite almost every time. I can't see why that would matter on these imagination-style problems, but I DON'T KNOW. In the end, I had him study the graphs in the SM to see what they came up w/ & then just moved on. :P
  8. Problem 3, x=2 looks like y=-8.
  9. Yep, that's what ds put. And the Google grapher did the same. And I did, too, but I took Alg 2 through ACE, lol, so I hesitate to jump right to THE BOOK IS WRONG. TWICE. IN ONE LESSON. Oh well. Let's move on! LOL The last lesson we had trouble w/ was yesterday. It asked for "reasonable graphs" for about 20 problems. The SM said, "These are some reasonable graphs. Maybe yours are even more reasonable!" :D Except. None of ds's matched the book. Now, I understand that they don't have to, but whereas for Geometry I was able to generally understand where the proofs had some leeway...well, good grief. HOW AM I SUPPOSED TO DO THIS? IF I CAN'T EVEN KNOW GENERALLY if he's right or wrong. I was freaking out yesterday, so I made him sit down & do a BUNCH of math, so I could know for sure whether or not I'd be able to teach it. Because if not? He can go down to the local high school for just this one class & take it there, & they were super friendly on the phone. But there's a soft deadline of tomorrow at noon--basically, they just don't want him to get behind, & I agree. IF he needs to go there for math, he should do that right away. This lesson, while it seemed very easy still, well, it's got me rattled again. I mean...I don't think I can do this w/out a reliable SM! *sigh* I feel very definitely ALL CAPS about TWO ERRORS in ONE LESSON.
  10. So I took pics. I found a button to "compress" them for web pages, which worked for changing my avatar earlier today, but they still won't upload. I put the pics along w/ an explanation of the problem on my blog as well as links that make ds's work look Really Really Right to me. But I'd find so much assurance in an errata page. Kwim? http://aubreylively.blogspot.com/2014/08/algebra-2-solutions-manual-vs.html
  11. Exercise 3-2, problems 3 & 5: 3. y=(-3/2)x-4 5. y=2x-5 I'll see if I can take a pic of the answer w/ my phone, since it's a graph. Basically--he's starting at--for ex, problem 3, (0,-4). The SM does the same. Then it seems to be a simple rise over run--over 2, down 3, etc. This is where the book is different on both of these problems (but not the rest in the lesson)--it goes over 2, down FOUR.
  12. 1. The easy question: Is there an errata page for Foerster's Alg 2/Trig Solutions Manual? I've googled & come up w/ nothing, but those pages always seem really tricky to find. :P 2. If there's not--have you guys noticed any errors in the solutions manual? We're dealing w/ a really simple problem in ch 3, & I'm convinced that ds is correct, but if he is, then that one lesson has at least 2 errors in the SM. And you know, that seems statistically unlikely. So...? I don't want to have this much trouble when we're only on ch3! *blush*

    A Small Quilt for Rosie

    For a pic, I just updated the other one on my blog. :P I'm sure there must be a magic "compress" button, but I can't figure it out. :/ Sorry.

    Yes, but first I searched shipping prices online & lost a day or two breathing into a paper bag. Then the nice lady at the PO said "Online prices are different." Although--acc'd to "online" prices, paying at the PO would have been more $$. Also, UPS. To Australia. Don't look at that, because that's black-market-kidney territory. :D The biggest accomplishment, really, was keeping the kids off of it. You'd think w/ pins & needles, they'd avoid it more. *scowl*

    Oh, AND--you guys SO did not need to send money for shipping, but thank you. You guys sent *to the dollar* what it cost to ship it. Thank you so much! (((ALL OF YOU)))
