Introducing some fun into my algebra class. I found this practice game where slope and y-intercepts are changed with a random card draw You have to start with the playing board. Equation changes to m and b template, There are three card that track changes to m and b, with equations, slope and y-intercept cards. This is not my invention and I can't figure out where I found this. Update from 10.1.12: Just got a tweet from @A_Morris01040 and I think this is his creation. Thanks Aaron for letting me know. I knew it wasn't mine, but I could remember where it came from. I'm pretty sure that I found it via the #msSunFun exchanges or the high school counterpart. The idea is that students start with an original equation, pull a slope card and then a y-intercept card. I copied each type of card on a different color so that I could put them in three separate buckets....and letting students draw from those buckets make the whole activity more "exciting".

In the picture, you can see two completed worksheets and a pile of the cards.

Using their slope card, students glue it into the middle box on the template and then they change the equation according to the card they pulled. Rewriting practice is pretty important at this point in their devleopment. The cards are pretty cool because they make them use and apply more math vocabulary words like "the slope doubles" or "the slope triples". Also, they create a new graph based on the slope card.

Next they pull a yellow card which corresponds to the y-intercept. And then they alter the equation according to that card and graph it. These cards asks students to "divide the y-intercept by 4" or to "multiple the y-intercept by 2".

By the time they're done with this first practice sheet, they've had several chances to practice. With so many different starting equations, the possibilities are pretty limitless. Students responded to this game and really liked the randomness of pulling the cards. Since they are different colors, it's easy for me to see if they're following directions and where I need to help out.

If you know the author of this file, I'd really like to give the them credit. I've taken their terrific idea and customized it to my room. It has pointed out to me how I need to devise a method for recording where I get ideas after I've downloaded their files.

I don't know the author but this is perfect for my upcoming unit! Thank you for sharing!
