Days 136-140: Closing out Trig

Day 140: Circles Pre-Assessment

Circles Pre-Assessment

Today, the last classes finished the Trig Unit Quiz. To prepare for our next unit (Circles), we had them do a pre-assessment, which included drawing circles. They seem to get the basic ideas, but seem to be hindered by the compasses themselves (which are somewhat cheap and flimsy). Toying with the idea of giving them pre-drawn circles. We’ll see.

Day 139: Class on the Go

Class on the Go

In addition to today being the day where some of our classes made up the Trig Individual Quiz, it was also the meeting of our Translation Club (something a few other residents and I started as part of a service project; we help students translate documents from English to their home languages). These meetings happen at lunch, which is the same time some students stayed to take their quizzes. As a result, we packed up and headed to Translation Club. However, some of the trig identities we wrote on the board didn’t make the transition, so I stole some space on another teacher’s blackboard and wrote them down. Make do with what you got…

Day 138: Reflection

Trig Unit Reflection

For the end of each unit, we ask students to reflect on the work they’ve done for the unit – what went well, what they’d like to improve upon, what pieces of work reflect their best work. We’ve decided that a short reflection worksheet is (so far) our best bet at getting that done.

Day 137: Ah-Jay-Sent

Ah-Jay-Sent

One of the things I’m thinking about is how to increase students’ use of academic language. This unit, many of them struggle with the word “adjacent”, which is something I take for granted. It’s not spelled the way it’s pronounced and it’s pretty complicated for just trying to say “next to”. So we wrote it on the board with a pronunciation key and try to make students say it as much as possible.

Day 136: Inverse Trig Diagram

Trig-Inverse Trig

Today was a quick lesson on Inverse Trig. One of my students asked when you use each of the functions, so I whipped up the following diagram on the spot. In retrospect, I wish I’d said “Ratio of sides” and maybe done something more specific with each of the trig identities. Students also seem to not connect “inverse trig” and “tan -1” (for example) as much as I’d like. For next time, I guess…
