Unit Circle

This idea really connects special triangles and the unit circle. I did something similar with my students and that's when they were able to start understanding why the signs change but the values don't in different quadrants.

Students match different forms of the same linear equation (slope-intercept, point-slope, standard) in this puzzle activity. Good practice for translating between the forms.

Why was I never taught this trick???

(free Algebra 2 warm up template). I shine either an equation or a graph on the smart board. If I shine an equation, my students know to sketch the graph. If I shine a graph, my students know to find the equation. From there, students find the vertex, y-intercept, domain, range, zeros and equation (if a graph was given).

Unit circle not using paper. Wish I taught algebra 2 just so I could do this!
