Corrected transformation game

I fixed my transformations game (and, Curmudgeon, I did make this public!!). It was pointed out to me that I did not make it mathematically rigorous enough by referring to the transformations as "move up 2 and right 2" instead of "This graph is a transformation of the graph f(x) = x^2 with a horizontal shift of 2 units up and a vertical shift of 2 units to the right" - so I fixed it. Thank you, S^2 for that!!

Enjoy and critique. I want to get better!!

At last a game I can believe in! *edited*

Here is a copy of a game for determining transformations.

I am not a big fan of games in math. I have always enjoyed the math sufficiently for it to be its own game. But, I know the kids enjoy games.

I have used Jeopardy as a review tool and a few others, but it seems like a lot of work on my part for little reward on theirs.

Mostly the lower level wants to play trashetball, bit it is to the wadded up paper (apparently mine is better than theirs and new paper better than trash) rather than as a reward for doing math.

In a class I took last week, the teacher used an awesome game. His had 4 parts: 6 graphs of functions, 6 graphs of the first differentials, 6 strips with description of the functions and 6 with descriptions of the differentials. He had us work in pairs (no hitchhikers), no competition, lots of discussion.

The link above will take you to the one I am using with Algebra 2 for transformations. I really love this game.

If you chose to make a variation (and the possibilities are there), please let me know what you will do. Here are some I have come up with but not created:
1) graphs. Have several graphs, then equations in y-intercept form, then equations in point slope form, then tables of values. This could easily become several different games.
2) microbiology: slides and their descriptions
3) Conic sections with descriptions and equations.
4) function families with graphs, name, equations
5) parabolas: graph, vertices, equations, roots, whatever

What I like is after it is created, it is one batch for all the classes and can be used as preview and then later as review. Just shuffle before you put it away. You don't even have to put them on separate colors.

Update: This is the first time I have used Google Docs and I did not change the privacy settings. If you tried to see the file, go back and try again, please.

An alternative to PowerPoints

This came up in a discussion of powerpoints, which one of the counties around here uses for EVERYTHING. First, how to make powerpoints stand out: vary the fonts and background color, and keep the verbage on the slides very simple.

Then, someone told us about Prezi. Here is an example of what you can do with Prezi.

[To see full screen and autoplay (it will be too fast to read, but it will give you a feel), take your cursor to the right side, bottom. Hitting the "play" arrow will pull one page at a time.]

Teachers can get it free.

I cannot see doing this for everything, but this would be an awesome intro to a class.

Teaching Tool: engaging the student

Mr. K posted an idea about letting the student draw the number line to decorate the room.

Part of what I have been thinking about is do I ask enough of the kids?

Could I involve high school students in coming up with my word wall? A number line for my room? Postable examples of good work?

I do put some on the bulletin board, but I think I need to do more.
