Plus, if it shows up on a standardized test, doing it on the calculator will be a time saver.<br /><br />This http://www.box.com/shared/zqvp98no61 is the scaffolded worksheet I created for students to teach themselves how to do it on the calculator.miss.calcul8https://www.blogger.com/profile/02014623484245570719noreply@blogger.comtag:blogger.com,1999:blog-6414622914006646376.post-18530046016850734002011-10-24T20:38:30.413-04:002011-10-24T20:38:30.413-04:00I'm so glad that the problems worked out for y...I'm so glad that the problems worked out for you! I'd only used them with my general kids, but I felt like it was a great intro to what a system was and what a solution meant (a lot of times the kids called the solution a "balancing point" or a "break-even point" which I totally encouraged as long as they knew what they were talking about!). I'm still amazed at how much better they'll work when the problems have some sort of context... and totally ticked at myself for not giving them that context more often.<br /><br />KristenKFousshttps://www.blogger.com/profile/04493982153040173831noreply@blogger.com
