Transformations - Geometry

Transforming 2D Figures
- Card Sort
A great card sort from the wonderful people over at the Mathematics Assessment Project. Here is a presentation I created for it. Here is a link to the folder containing my student handout files.
Combining Transformations
- ​Card Sort
Another card sort from the Math Assessment Project, this time focusing on combining transformations. Here is the slide deck I made for the lesson. Here is a link to the folder containing my student files. 
Transformations Golf
Oh. My. Goodness. Just when you though Desmos couldn't get any better! Here is a link to the activity.

Congruence - Geometry

I don't have anything spectacular yet for triangle congruence. Here, we're mostly working on proofs. If you're interested in those, let me know. I've got lots to share there. 

Constructions: 

The basic outline for my constructions unit is to play with some online tools to get the hang of the rules of the game. Then we formalize it a bit when constructing shapes by hand. 
Intro to Constructions: Science vs Magic
Play with http://sciencevsmagic.net/geo/. See how many of the challenges you can complete. Submit screen shots of your completed challenges by placing them in a Google Doc in your shared google folder.
​Start Geometry Constructions Project
Euclid the Game
Constructions Unit Day 2
Play ​Euclid The Game in pairs. One person operating the laptop and the other writing down the steps used to complete each level. After each level, switch who is on the laptop and who is taking notes.
Constructions Project

I stole this directly from Lisa Bejarno. Love it! I've done this for several years now. The link to the left are some pictures from a recent go round. Here is a link to my first and second student handouts and the basic rubric/checklist I use to grade them.
And now for the not-so-very-awesome stuff. Here are some of the worksheets we use when practicing constructions:
Constructing Perpendicular Bisectors and Angle Bisectors
Here is a link to the practice work we use. 
Constructing ALL the Medians, Angle Bisectors, and Perpendicular Bisectors in a Triangle. 
Here is a link to the practice work we use. Changes for next time, refer to these by their fancy names: orthocenter, circumcenter, centroid, and Incenter
And or course... Geogebra. For one of our days, I have students practice creating the figures we did by hand using the Geogebra tools.
