All of a sudden, I've started looking around and wondering where all my friends went and if the way I've been teaching is healthy for either me or my students. I'm a better teacher when I'm relaxed. The biggest problem is while I relax, I worry about all the stuff that needs to get done but isn't getting done and the only way to relieve the stress this worry causes is by working...Lizzy-Senseihttp://www.blogger.com/profile/16697599110257655917noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-34887080511687959202012-01-19T18:01:17.651-05:002012-01-19T18:01:17.651-05:00Thanks!

Depending on the choice for A, the equation is true or false. The language "solve for x" hides what is really happening: finding the value(s) that make the equation true.<br /><br />Going the other way with this ("a specific number we don't know") leads to big problems quickly, in equations with zero or multiple solutions, and especially in equations with an infinite number of solutions, such as 2x+3y=12 or x+1=1+x.<br /><br />This actually reduces the number of different ways to have to worry about, and eliminates the "unknowns" thing altogether.<br /><br />Thanks and keep up the great work!patternsinpracticehttp://patternsinpractice.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-63950924728120003712011-11-13T13:07:15.716-05:002011-11-13T13:07:15.716-05:00I like the idea of using different words for unkno...I like the idea of using different words for unknowns and variables.

My math department (all three of us) had a conversation a few weeks ago about the difference between a variable and an unknown, and how and when we would teach this distinction. [FYI: the decision was 6th grade: unknown, 7th: variable]<br /><br />But it got me thinking about all the different ways we use letters to represent numbers. So far I've come up with four: 1. variables, 2. unknowns, 3. parameters (like m & b in y=mx+b), and 4. special numbers (like e, i & pi). I like your distinction between variables as quantities that change and as placeholders. <br /><br />One of my goals in sorting this out is to be very consistent in my language with students and only refer to the letter with its actual name and not just call everything a variable, as I often slip up and do. I'll probably wind up creating a "toolkit" note page about it at some point when I get around to our variable unit in 7th grade.betweenthenumbershttp://betweenthenumbers.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-17719376393066578542011-10-11T21:09:42.136-04:002011-10-11T21:09:42.136-04:00Thanks for stopping by!

I think the key is to start the quiz corrections as an in class activity along the lines of "Okay, now everyone fill in the reflection questions while we hand back the quiz. .... So, I noticed a lot of people had trouble with ____ let's fix that one together. ... Now let's take 5-10 minutes to correct the rest and then be sure to staple and hand them in when you're done." After the first time, going over ones everyone got wrong is good, but the rest can be assigned for homework if you're short on class time because they've seen the benefit of corrections.<br /><br />Link to the quiz correction sheet: http://dl.dropbox.com/u/5478453/Quiz%20Corrections.doccrstn85http://www.blogger.com/profile/00549943329133396794noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-28610578461430115822011-10-11T20:24:18.887-04:002011-10-11T20:24:18.887-04:00Thank you for this post!

I started doing quiz corrections and was somewhat disheartened by the number of students who took advantage of the opportunity to earn half of the points they missed back. I asked them to explain what they did wrong, show/explain how to get the right answer on a separate piece of loose leaf. I think I am going to steal your doc for quiz corrections because providing students with the template may encourage more to partake in the opportunity. I really want students to learn from their mistakes and understand the content so ultimately I'd like EVERYONE to turn one in.<br /><br />Do you have suggestions on quiz format? You mentioned a half sheet? My school does not allow for test corrections but they do allow for quiz corrections and out of 65 students last quiz only 6 students turned them in (and none of the actual failing students). I would love to hear more about your procedures. Do all students have to fill out the first sheet? Thanks for all your help!

That's the "second question" which I didn't really go into. We also investigate and discuss those types of questions throughout class.<br /><br />I am rethinking the phrasing, and I get your adverse reaction to it, I feel the same way about the generic PD. But I still want students to reflect on what it was they were supposed to be studying today, and so far I don't have a better way to ask them to prove that they accomplished the goal.crstn85http://www.blogger.com/profile/00549943329133396794noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-74430232623324165662011-10-03T19:41:58.859-04:002011-10-03T19:41:58.859-04:00It would be better to ask them to write something ...It would be better to ask them to write something that requires mathematical thinking related to the day's topicâ€”like "why does AAA not prove congruence?" "If you draw two circles of different sizes, how many points can their intersection be? What about circles of the same size?"<br /><br />Asking them generically to reflect on the "objective" does little for their mathematical understanding. If you are looking for real-world connections, many (most?) people are turned off by discussion of "objectives", "mission statements", and other time-wasting exercises that managers inflict on people trying to get some work done.gasstationwithoutpumpshttp://gasstationwithoutpumps.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-4375129538480786722011-10-02T12:54:46.448-04:002011-10-02T12:54:46.448-04:00First, a student certainly won't fail math bec...First, a student certainly won't fail math because they don't submit their journals; the point is not to penalize students, but to give them an opportunity to reflect. <br /><br />It was a particularly useful exercise in my pre-algebra class because that course was entirely context based math. Students studying the "dogs and buns" problem needed to tease out that we were studying multiples, not hot dogs, and directing them to the objective helped them to do so. <br /><br />This year I teach mostly Geometry, which is filled with vocabulary. The more students can use the vocab that we learn, the better. All the ELL trainings, SPED trainings and literacy workshops I have attended say the same thing: the more opportunities they have for writing, the better. Sure, journaling on its own isn't going to fill in all those gaps, but it's a start.<br /><br />If you have a suggestion for how to rephrase the "how did you meet the objective" question, I'd love to hear it. As I said, I've gone back and forth on how to phrase it; I want students reflecting on and sharing what they learned and what they're struggling with, but without requiring paragraphs each day.crstn85http://www.blogger.com/profile/00549943329133396794noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-34303180576928967582011-10-02T12:28:10.593-04:002011-10-02T12:28:10.593-04:00I too have to ask the "writing in math class?...I too have to ask the "writing in math class?" questionâ€”not because I object to writing, but because pointless writing does not help students.<br /><br />If you were teaching them how to write mathematics, using Halmos's "How to Write Mathematics" essay, for example, I'd applaud. But "how did you meet the objective?" is not a prompt that will lead to either good writing or good math. All it is likely to do is to turn off those students who are good at math but not good at writing (like the English language learners).<br /><br />There are some places in math classes where writing might be valuable, but journaling does not strike me as one of them.<br /><br />Disclaimer: my son is a very adept math student who would balk at this sort of exercise, and fail a class rather than do it, so I have a rather stronger than usual negative reaction.gasstationwithoutpumpshttp://gasstationwithoutpumps.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-42197648630078268942011-09-25T20:01:47.166-04:002011-09-25T20:01:47.166-04:00Cool, thanks!Cool, thanks!crstn85http://www.blogger.com/profile/00549943329133396794noreply@blogger.comtag:blogger.com,1999:blog-355442528570693080.post-54661231635596778162011-09-25T19:58:09.621-04:002011-09-25T19:58:09.621-04:00For about $10 you can get a custom stamp made.
