Angle Pair Nitty Gritty

As I was merrily going along teaching linear pairs and vertical angles and corresponding angles and such, it came to my attention that various students were not "there" yet with internalizing the pictures and definitions, so I came up with this activity:

I like the activities I've seen where sometimes the answer is "none" and sometimes there's more than one answer, and sometimes the answers are repeated in different questions. I've tried to incorporate that style into these problems. I think it worked pretty well.

I'm also giving them a quiz on 6 types of angle pairs for the next grading period. I told them they have to identify each angle pair correctly, and spelled correctly, and no abbreviations, and no doctor handwriting, and in a timed manner. If they miss ANY, they get a 0%, and they have as many tries in the next 6 weeks to get it 100% correct. I likened it to recognizing the letters of the alphabet. It sure would be a shame if they couldn't and/or it took them a long time to process the information. I restated the fact that geometry (math) is like a foreign language, and they have to have fluency with all the words.

In other funny news. A student whose grade is suffering and who came in for tutoring today and was actually grasping things said, "wow, I should really listen more in class because this makes so much sense."

1. Ms. Cookie--I LOVE this idea! I just wrote a review on pairs of angles for my students and this is a great activity to supplement it!
Can I "steal" your idea and worksheet??

3. I love this - where do you draw your pictures?

Oh, the girl I wrote about earlier walked in this week and said "I can't remember my best friend" and it took me a minute - but I reintroduced them. She really really likes it!!

4. Ackh! What are you doing up so early?? Isn't it like 3:40 or something there?

I use the drawing tools in Microsoft Word. I use the line, circle (reduced and filled) and the weird line thing where you can make connected segments, and they have a parallelogram picture you can expand and rotate and such.

Yay for memory tools and processes.

Thanks for sharing your worksheet! It looks great, and it will be a good challenge for my students. We have moved on to congruent triangles, but I will use it for review before the semester exam.

6. LOOKS AWESOME...thanks for sharing! I don't even have time to think of extra things. But my kids need this too.

7. Question:
Why do you call it Same-side Int. angles instead of Consecutive Int. Angles?

8. Hmmm, I guess different books must call them different names. The books I've seen call them same-side interior.

9. I am using this worksheet right now and I think it is really helping my students see that things aren't always congruent. Even though I am through the chapter in the book that addresses this content, I am going back and having the students take a quiz on it next week. I like the idea of having to retake it, although I'm not sure how it would fly with my department if I did the 0% if they get any wrong.
This may be an odd question, but is there any way you could email me the word doc so that I could change "same-side int." to "consecutive int." since that is what our book calls it and our state test?

10. ER: if you download it (click on the "this activity", then I believe it's just a file that you can change at will. Is that not working for you? Let me know, and I can direct e-mail it to you.

11. oh that worked. I clicked on the picture and downloaded it from there, and it just came up as a preview file.
Thanks, this is a great thing. Good WORK!!!

Great worksheet! I'll have to remember that when I'm teaching Geometry next semester.

13. Thank you for sharing this. I altered it a bit for my class - but absolutely love the idea! Thank you for being kind enough to share!

14. Thanks for sharing! Is there an answer key for this too?

15. can you provide an answer sheet?

16. Where could the answer key be found to this?

Lovely work! Is there an answer sheet by any chance?
