### Special Triangles

We are just finishing up trigonometry and special triangles in geometry and moving on to areas, but as with all skills, they need to revisit the topic a few times. Here's a sheet I made up that I'll be giving my students next week.

EDITED LATER TO ADD: Well, after I made the sheet, I thought about how much I like the puzzle sheets with answer banks, so I improved it to make the following

1. Ooh, perfect timing. I just taught my Mathcounts kids about these special triangles, and you just saved me making up a worksheet :) Thanks!

2. Ooh, even better. Thanks so much for sharing!

btw, did your blog disappear for a week or two? I kept getting an error message from blogspot -- I was worried!

3. I'm glad you liked it ... hopefully it does the trick.

Yeah, it disappeared for a week. Now it's back.

Thanks,

Ms. Cookie

4. Cool fact, btw. I didn't know ;-)

5. The worksheet really did the trick for these kids. I need to use the self-checking mechanism of the puzzle sheet more often. That was very helpful because the kids could take it home and work on it and know whether or not they were on the right track.

6. Thank you for sharing, you made my Sunday. I guess when I think about it, when I'm revisiting math to teach and try the problems, I immediately check my answer to see if I know what I'm doing.

7. I really like this idea of going from numeric answers to a sentence. I had done it a looong time ago but have forgotten it since. The one time I did this, I had made it into a treasure hunt. Your sentence contains a clue for where the treasure is hidden inside the classroom room! The trouble was, the kids got so excited over the treasure that they started to get really rowdy/crazy. :) Newbie mistake. haha
