Next slide left for reference This Transformations Activity is from Honors Geometry BUT takes 90 minutes. Certain problems could be picked from it if you feel your students need transformations practice. I don’t think I used that activity at all last time…I felt my students needed more practice with the material in the 2nd half of the unit. ~ T Walden 
