Hello everyone and welcome to this week's #mathchat
11:34 pm
ColinTGraham:
If it's your first time, don't try to follow everything, just interact with one or two people. Don't forget the hashtag ---> #mathchat
11:35 pm
ColinTGraham:
Tonight we are going to do a show and tell of successful lessons, ideas and useful resources! #mathchat
11:36 pm
ColinTGraham:
Don't worry about checking links, they will all be recorded in the archive later. #mathchat
11:37 pm
ColinTGraham:
So, what do you consider your most successful lessons/ideas? Why do they work or why do you think they succeed? #mathchat
11:41 pm
mathsatschool:
#mathchat Taking lessons outside of the confines of the c/room. They remember context more than content.

ColinTGraham:
@mathsatschool How far outside? Just somewhere else in the school, playing fields,...? #mathchat
11:44 pm
tperran:
#mathchat As someone who teaches 90 minute blocks, I find success when I employ multiple modes of learning.
11:45 pm
tperran:
RT @mathsatschool: #mathchat Taking lessons outside of the confines of the c/room. ->>We did this with clinometers and trig ratios.
11:45 pm
ColinTGraham:
@tperran What do you find is the best size of block/mode before you change, Tom? #mathchat

@KimberlyLBeane Just got out of a starbucks "meeting" to go over the day! Very excited as well. We love our NJ teachers! #mathchat
11:48 pm
tperran:
@ColinTGraham #mathchat This week it was a simple triangle sort where we asked students to discuss and sort triangles prior to lesson ~15min
11:49 pm
tperran:
#mathchat The students were really engaged and communicating about math. It was great to see! They usually go off task within 5 min.
11:49 pm
danielespejo:
#mathchat I've done the usual trig lesson in a field, but I had students use real survey equipment and find a 'treasure'. Most got it.
11:50 pm
ColinTGraham:
@tperran Do you mean the first 15 minutes was the sorting before you did any teaching, or was it the 'homework'? #mathchat
11:51 pm
danielespejo:
@tperran I have also been exploring more discussion activities, including online. A bit here:http://bit.ly/d53JS3 #mathchat
11:53 pm
ColinTGraham:
@danielespejo Have you tried geocaching as well? When you say 'usual trig lesson in a field' what is that exactly? #mathchat
11:54 pm
tperran:
@ColinTGraham #mathchat We used the sort to open the lesson. I just displayed various triangles on the and then asked students to group them
11:55 pm
ColinTGraham:
One of the most interesting lessons I did was classifying quadrilaterals - based on angles diagonals cross at, parallel sides, etc #mathchat
11:55 pm
danielespejo:
@ColinTGraham I haven't done geocaching but I've been wanting to! #mathchat. Would be interesting to see how others have done it.
11:55 pm
ColinTGraham:
RT @danielespejo: @ColinTGraham usual lesson = having kids use trig (right angles) to find 'places" #mathchat
11:56 pm
tperran:
RT @danielespejo: @ColinTGraham usual lesson = #mathchat We used ours to estimate height of objects (tree, light towers, telephone poles)
11:57 pm
ColinTGraham:
@danielespejo So is this a 2D scenario, ie the triangles are constructed on the ground or do you go 3D with tree heights etc. #mathchat
11:58 pm
ColinTGraham:
Another lesson which surprised me with its success was getting students (13yo) to make simple slide rules... #mathchat
11:58 pm
danielespejo:
@ColinTGraham yeah, 2D trig, might have been neat to find something on a 'pole" of some sort to add the third dimension #mathchat
11:59 pm
tperran:
@ColinTGraham Did they know what a slide rule was when you started? #mathchat


danielespejo:
@ColinTGraham Sliderules sounds like fun, but I wouldn't know where to start! #mathchat

ColinTGraham:
@tperran No, we did number line additions as a slide rule, then I said could we do this for multiplying instead...? #mathchat
12:01 am
tperran:
#mathchat Speaking of trig, We had a great lesson using Google Earth to find extreme ski slopes in different locations http://bit.ly/aylLoB
12:03 am
ColinTGraham:
@danielespejo There is an online sliderule 'museum' http://sliderulemuseum.com/ which has lots of great materials. #mathchat
12:04 am
ColinTGraham:
@danielespejo Making two number lines and using them like a slide rule can also help with introducing/reinforcing directed numbers #mathchat
12:05 am
danielespejo:
@tperran I hadn't even considered google earth. Wonder if you could use it to 'guess' distances to a 'treasure' or sunken ship #mathchat
12:06 am
danielespejo:
@ColinTGraham I shldnt be surprised, but I am. Can find anything online can't you! #mathchatRT@ColinTGraham http://bit.ly/4rzJry
12:08 am
ColinTGraham:
@tperran @danielespejo I've thought about using Google maps, where Ss have to place markers according to a co-ord grid. Untried! #mathchat
12:08 am
danielespejo:
@ColinTGraham That's what i'm thinking #mathchat Definately going to look into that
12:09 am
ColinTGraham:
Any other ideas or successes? #mathchat
12:09 am
danielespejo:
@ColinTGraham I haven't put enough thought into these tools in math. Sad I'm a math teacher and Tech consult. #mathchat
12:11 am
danielespejo:
Have had kids doing surveys to get data before studying stats and linear algebra #mathchat
12:11 am
ColinTGraham:
@danielespejo Sometimes, the tech consultants spend so much time telling people about tools, they don't get time to use them! #mathchat
12:12 am
tperran:
RT @ColinTGraham: Any other ideas ? #mathchat We had a tesselations "art gallery" one year. Students created then critiqued each others work
12:13 am
ColinTGraham:
@tperran How did the critique work? Was it subjective, objective or a mix of the two? #mathchat
12:13 am
danielespejo:
@ColinTGraham :) Thanks for making me feel better about that! I guess we can't do everything well #mathchat
12:14 am
tperran:
@ColinTGraham #mathchat Students had to determine the type of translation used to create the work and tell whether or not it was correct
12:14 am
ColinTGraham:
@danielespejo Do you go into survey design first or just let the kids get on with it and discuss design of surveys later? #mathchat
12:15 am
danielespejo:
Matchat @lcarroll94 was telling me yesterday of a Glog assign in math where kids connected math to the world #mathchat Had a great rubric..
12:16 am
danielespejo:
@ColinTGraham I think i've done it both ways, but usually talk about survey design first #mathchat
12:16 am
ColinTGraham:
@tperran So I am assuming you provided the criteria for the critique, rather than the students! #mathchat
12:18 am
danielespejo:
@tperran Sounds great! I love when kids have to explain things at that level #mathchat
12:18 am
tperran:
RT @ColinTGraham: #mathchat ->It was also to assess their understanding of the concepts of tesselations and translations.. They enjoyed it!
12:19 am
ColinTGraham:
Do you tend to find that some kind of 'practical' problem or application of maths seems to be more successful? ie 'hands-on' #mathchat
12:19 am
tperran:
@danielespejo The students had fun doing it too and were highly engaged. #mathchat
12:22 am
danielespejo:
Thanks for the #mathchat @tperran @ColinTGraham , but I've gotta run!
12:22 am
tperran:
#mathchat Here is another engaging "filler" activity that our Ss seemed to enjoy: http://bit.ly/cFObn1Comp. based and interactive
12:23 am
ColinTGraham:
@danielespejo OK, thanks for joining us Daniel! #mathchat
12:24 am
tperran:
@danielespejo Thanks for the convo. Check my wiki, I put interesting links there when I find them.http://bit.ly/9FxkuJ #mathchat #edchat
12:24 am
ColinTGraham:
Puzzles seem to be popular too, when they are not too difficult. #mathchat
12:24 am
danielespejo:
@ColinTGraham thanks for the convo and facilitating! #mathchat
12:25 am
ColinTGraham:
OK, last five minutes... anyone else want to jump in with an idea or a link? #mathchat
12:29 am
tperran:
@ColinTGraham I also put interesting math links on Diigo: http://bit.ly/cXnl4G Thanks for the #mathchat, Colin. See you next time!
12:30 am
ColinTGraham:
Ok, thanks for the conversations. Let's hope we get a few more ideas added on Monday when we return to this! #mathchat
