Can't Find? Geometry

grade4curlyQ · **Can't Find? Geometry** 03-11-2007, 05:28 AM

Hea everyone!
I'm thinking there was once a post on the 4th grade board from someone who broke down their geometry unit into "chunks" of what they taught. I've searched for it, yet can not locate it. How do you "chunk" your content? (Points, lines, rays, segments) ........?
Thanks

Hi, this post is from a week or so ago, but I thought I'd reply anyway...here's how I "chunk" my geometry unit:
1. Plane figures and solid figures--polygons, 3-d figures, sides, vertices, edges, faces, etc.
2. points, lines, segments, rays, angles / acute, obtuse, right, straight angles / parallel, perpendicular, intersecting lines.
3. triangles and quadrilaterals--more specific--isosceles, equilateral, scalene, acute, obtuse, right triangles / squares, rectangles, trapezoids, parallelograms, rhombi
4. Circles
5. transformations (slides, flips, turns) congruence, similarity, symmetry
6. Geometry and measurement--perimeter, area, and volume

I really appreciate it! I am wondering though, do you know of any sites with error analysis activities as well as classification GO's? Even feature analysis would be AWESOME!

Still searching ............. if you find anything let me know.

No, sorry...those things aren't in my standards or curriculum, so I'm not super familiar with them
Thanks!

What are GO's?

For error analysis, after I teach a concept, I look at a problem and then "work it out" for the students making some kind of mistake. Then, I ask if I'm doing it right and act confused when they say it's wrong. They have to explain what I did wrong.

Hope this helps and it answers what error analysis is!

Go's are Graphic Organizers. I use error analysis in every subject area to teach critical thinking skills. GO's help the students organize their reasoning skills when I use error analysis.
I did find some materials in a book called "Organized Thinking" that has the children categorize geometric figures according to feature analysis. I'll try to post a couple of pictures of what I used. I'm still looking for line, line segment, ray, feature analysis resources though. These are the ones the children forget MOST often..........they get them confused.
One of my students was asking for help on remembering the difference between slides, turns, and flips so we took some die cut shapes and placed them (she did......with little guidance) poster paper and named them "Piggy Slide" - "Gator Turn" - "Cow Flip" then she glued them down in the correct position. It gave all of us a good visual representation to build understanding. The "cow flip" looked like he'd gone mad so we nicknamed him Mad Cow Disease.

THANKS!

Here are some pics of our geometry unit.
BTW......the # of edges for the cone & cylinder that we chose to go with was zero because of the "2 straight planes intersecting make an edge" definition. In the upper geometry courses the children will learn the "boundary between 2 smooth surfaces" method and accompanying theorems. This can go either way depending on how deep you are required to go with geometry in the 4th grade standards and how questions are phrased on the state tests.

I love your pics! Do you have any pictures of your classroom? I'm teaching 4th next year and they seem so young.

little 20' by 20' room?

Yeah, I have a couple. It's pretty sad when the number of students (25) is greater than the length or width of the room. And thanks!

Here are three other pics of the writing materials & non-fiction book displays & section of the room.

I love to see other teacher's pics to get ideas! I have 2 slide shows running on my web page with more pics to view. Send me a PM and I'll give you the site. Do you maybe have some pics to view?

I've since moved all of the writing materials to a large book shelf since we had so many donations for the writing center & this small table behind the door is now a writing table with a lamp. Cozy.

Good luck next year w/ the 4th grade! I love this age group & what I teach!

Are you leaving the middle school or is your school 4th through 6th grade?

I am new to this site. Just registered today, and I love it! I am one of three 5th grade teachers in my district. We each are taking different parts of the curriculum to dig into and write up plans for. I am working on a Geometry unit and ran across your pictures. I love them and would love to visit your classroom website you mentioned. Are you going to post your address? Also, I haven't heard of Error Analysis. What exactly is that?
