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.
