Transformations - Geometry
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.
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.

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.
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.
And or course... Geogebra. For one of our days, I have students practice creating the figures we did by hand using the Geogebra tools.
