My kids started with little background, I front loaded with two column notes (warm up) then I quickly went over...then stated the objective of the activity was for the students to use the vocabulary to solve the puzzle. The conversation was awesome. Loved it. The second puzzle is a big jump and we did not have time to explore it completely, however I will return to it!

You're absolutely ...Really great point, Katrin. You're absolutely right that students can solve angle problems without knowing the names for pairs of angles. I would like to think that students tend to see the numerical relationships over the vocabulary relationships here, because of the visuals and interaction. The more I do this activity, the more I value the discourse students have when working together to solve these challenges. Furthermore, I think it's important to prioritize the name recognitions for the angle so that students become familiar with the names of commonly used angles in geometry. For example, I would rank vertical angles and linear pair pretty high on my list. It's a lot easier for us to communicate by saying vertical angles instead of a student pointing and saying something like, "this angle and that angle across from it."<br />The mathematical goal here is to not solve angle problems, as I'm sure you see. This activity's mathematical goals has evolved into student discourse around angle relationships where students construct arguments, use logic, and become more familiar commonly used angle names in preparation for many geometric activities, including (but not limited to) proofs.<br /><br />I'm curious, if you had to prioritize the names of the angles, which would be your top two?Andrew Stadelhttp://www.blogger.com/profile/06699410662148629132noreply@blogger.comtag:blogger.com,1999:blog-2256375873271579383.post-24005968433347467072016-07-12T05:29:57.603-07:002016-07-12T05:29:57.603-07:00For me, this activity is too much about learning w...For me, this activity is too much about learning words.

When the kids came in, they were SO curious! I had to get them through being able to name the special angle pairs first. They practically jumped out of their seats when they finally got to do the activity!<br /><br />As an extension to this activity, I had them making their own puzzles like this. A lot of fun to go through them: had them realizing one clue per angle pair wasn't enough!Mrs. Palmerhttp://www.blogger.com/profile/11427341201863705060noreply@blogger.comtag:blogger.com,1999:blog-2256375873271579383.post-80314347485785603192013-07-14T19:54:40.866-07:002013-07-14T19:54:40.866-07:00Thanks for stepping this out, Andrew.

Great way to learn the vocabulary and really get at the relationships involved - thanks!Annahttp://www.blogger.com/profile/13960574914938362477noreply@blogger.comtag:blogger.com,1999:blog-2256375873271579383.post-68392531070590015442012-10-25T14:20:20.805-07:002012-10-25T14:20:20.805-07:00Love this, especially the non-parallel example. I...Love this, especially the non-parallel example. I have had students in the past who assume that alternate interior angles are always congruent, and this activity lends support to the vocabulary. Also, the transversal become the star of the show, as some some of the pairs are alternate-interior RELATIVE to the transversal they share.<br /><br />Do you have any magnetic boards in your room? For me, this would be idea for small magnets to make it easier to move the numbers around. Would also make a nice puzzle computer app.Bob Lochelhttp://www.blogger.com/profile/10039048264802808588noreply@blogger.com
