# Day 51: Triangle congruence notes: making it all official

This was not a highly engaging lesson. I found out that all other teachers were showing movies today, & I was the only one "making them learn"

# Day 50: Lying to my students

[update 3/27/16: I described how I use AngLegs to intrduce this lesson here] I lied to my students today. Really, I fantasized, because I wish my lie was true. I told them that I was going to choose some of their work and send it to Ohio for another math class to critique. Then I … Continue reading Day 50: Lying to my students

# Day 49: Intro to triangle proofs – better then expected!

I debated for a long time on the best way to teach triangle congruence proofs. I decided to start with the Math Assessment Project's lesson Analyzing Congruency Proofs. I broke it into a multi day lesson since we have 50 minutes classes, and I do not want to rush this! Some students got frustrated with … Continue reading Day 49: Intro to triangle proofs – better then expected!

# Day 48: Quiz Friday

I'm not looking forward to grading them, but students said they felt prepared for it. Update 10/28: It went rather well. The average was above a 3 in every class (out of 4). There were 1 or 2 in each class that scored a 2 or 1.

# Day 47: Tying up loose ends

Since I had quite a few students struggling with their origami angles project as well as many other assignments, we broke into groups by needs (project, update INB, extra challenge, study for quiz). Yay differentiation! Students all seemed relived to have support to work on what they needed. Big quiz tomorrow will tell me if … Continue reading Day 47: Tying up loose ends

# Day 46: Triangles & angles & I am feeling like a crappy teacher

Today is Mole day (6.02 x 10^23), and I said happy mole day to the staff this morning. Nobody, not even the chemistry teacher, could explain what a mole is. Geez! I decided to go with workstations because I know they needed more practice with all of the angle stuff. I'm not feeling very creative … Continue reading Day 46: Triangles & angles & I am feeling like a crappy teacher

# Day 45: Starting Triangle Inequality

I will not tell them how to determine the lengths that do and do not form a triangle. I will not tell them how to determine the lengths that do and do not form a triangle. I will not tell them how to determine the lengths that do and do not form a triangle. I … Continue reading Day 45: Starting Triangle Inequality
