FLASHCARDS
This past week my sophomore class was working on angle relationships. I wanted something that went beyond the definitions because many of my kids could tell you that complementary angles add up to 90 degrees, but then have trouble turning that into an actual equation.
This was an attempt to make something that was more useable than a definition. The kids started by cutting out the first six card fronts and attaching them to index cards.
Next we went through them card by card labeling and coloring the angles, writing the relationship in words, and then writing an equation.
After going through all of them, I gave the kids the six card backs. They had to look at each one and decide which relationship it showed and tape it to the right card. They needed have me or someone with the correct answers check their cards before actually taping.

Here is a kid matching up his cards 
After putting the problems on, we went through the problems and discussed how to use what we knew to write and solve an equation. Going through this took very different amounts of time in different periods of mine.
Hi Sarah! Great post! I am a new teacher (trained in language arts, but teaching in all subjectseek!), and am trying to find resources to teach math to my (struggling) students. I love this lesson, and was trying to print out the flashcards, but it wants me to pay money (even though it says they're free...). Any suggestions? I think maybe I'm doing something wrong.

ReplyDeleteThank you for such a a complete resource on ISNs. I started having my HS geometry students create foldables second semester this year in hopes of salvaging my unsuccessful attempt at having students create a journal. The foldables have been INCREDIBLY successful; the journals are better but not what I now know I want...ISNs like yours! I've been researching and yout blog is by far the most helpful. So my plan is to conyonue to use foldables and create ISN next year. I did not see the back side of the amgle pairs flashcards, did I miss them or are they missing? Again thanks so much for sharing and helping a 20+ year veteran try new ideas!

This looks like such a wonderful idea! (I want to see specifics but the site says that it was deleted... would it be possible for you to post a document or file in which I can clearly see what was on the flashcards themselves??)
ReplyDeleteHi. I created a second page of angle pair types to as closely match what you did as possible. Here it is. https://www.dropbox.com/s/kh6ry4lk6x63ujb/Types%20of%20Angle%20Pairs.docx Hope you find it helpful, and that I haven't offended you. Thank you.
