Draw (freehand, with ruler and protractor, and with technology) geometric shapes with given conditions. Focus on constructing triangles from three measures of angles or sides, noticing when the conditions determine a unique triangle, more than one triangle, or no triangle.

I think the lesson would benefit from more definition on the rolling of the dice. I know some of my students would want to roll the dice all 20 times and then create the triangles afterward. I would want to see what procedure I would want in my class: DO I want my students to roll the dice once, then create the triangle and record, then go to dice roll number 2...? I just think if I want a certain procedure then I would add it to the instructions. The assessment portion/questions did a really effective job of covering all the information I wanted to know from my students. Kudos for another great resource from this user!!! I've been rating a lot of your resources during a SML marathon, and I have to say you have a great collection! Thanks for your hard work!!!!!!
