I adapted Jeff De Varona's Diamond Building lesson into a 3-act task, but instead of having act 3 be a reveal of the actual height, I had students calculate the height a second way to confirm their results. It took 2 short class periods (about 40 mins each) with my struggling students, but it may be able to be … Continue reading The Diamond Building

# day 107: Wrapping up the trigonometry pile up

I planned to allow 10 minutes for students to ask questions & make progress on the triangle pile up. They make everything into such a big deal. After a reassuring talk about how I am confident that they have a lot of tools in their math bag of tricks, students did realize they could do … Continue reading day 107: Wrapping up the trigonometry pile up

# day 106: Triangle Pile up

Today we did our first Graphing Stories warm up & the students were very upset that we got rid of estimation180 I'm going to have to bring it back in a month or two. But, man did they need the practice graphing! It was a mess and totally worth it. I heard students asking if … Continue reading day 106: Triangle Pile up

# Day 104: Right triangle trig with words

I printed the questions on cards and gave a set to each group to encourage collaboration. I just gave them to the students. No instruction, no fancy schmancy notes. They learned through struggling and did great! [update 2/28: Look! Research to support productive failure!]

# Day 103: Do wat’cha need

I put together an elaborate plan today to complete a station activity practicing different types of right triangle trigonometry. Then, this morning before class, I talked to the students, and i listened. They told me that they needed more time & they had questions....I adapted. So today after our warm up, I provided students with … Continue reading Day 103: Do wat’cha need

# Day 102: Practice Right triangle trigonometry

I learned quickly today that I was a little too ambitious in my pace. Students were great at determining opposite, adjacent, hypotenuse & selecting the appropriate trig function, but they really struggled at solving for the unknown side. Being that it was "What we've been doing Wednesday" I changed the warm up after my first … Continue reading Day 102: Practice Right triangle trigonometry
