### Lessons Taught and Lessons Learned as a High School Math Teacher

I get e-mails from people all the time wondering how to get started with interactive notebooks. Honestly, I'm not quite sure how to answer this question. How does one get started with interactive notebooks? I know these aren't the steps people want to hear, but I think this pretty much sums up the process: Step 1. Adjust your expectations.

### Week 35

I taught the kids a new card game to practice adding and subtracting integers. We had fun and the kids loved practicing this way, instead of just working out problems with paper and pencil. The red cards are negative and the black are positive. Each player starts with 6 cards, drawing one at the beginning of their turn and discarding one at the end. The goal is to play pairs that equal 6 or -6. The person playing 3 pairs first wins. The other players add the absolute value of their cards to…

### Slope-Intercept Form Battleship

I've seen a few variations of using the famous game Battleship in math class. Who among us hasn't used it (or at least the concept) when reinforcing graphing coordinate pairs? Taking it in a slightly more advanced direction, let's make a 4 quadrant Battleship grid. And let's require kids to write equations in slope-intercept form, graph them, and develop a strategy for this process. (Putting equations in point-slope would be a great substitute if you want one.) Here's how it works: Materials…
