Obviously I know why you have to double the equation, but since you aren't using equations at this point I'm interested in how you make that connection.<br /><br />~ NathanNathanhttps://www.blogger.com/profile/09850528491524825885noreply@blogger.comtag:blogger.com,1999:blog-5473916205424933781.post-62333697681210006292015-09-30T14:03:25.254-04:002015-09-30T14:03:25.254-04:00Blogging every day is definitely a time commitment...Blogging every day is definitely a time commitment, but it helps me keep a record of what I have done and to reflect on my practice. The fact that it is helpful to others is fantastic.

Thanks for stopping by my blog :) I had actually saved all the solved examples from a previous class and only showed them once everyone in the class was done or at least on the right track to solving the question. I have created them during the lesson before - which way I do it depends on the particular class on that day.Mary Bourassahttps://www.blogger.com/profile/12427568524129802618noreply@blogger.comtag:blogger.com,1999:blog-5473916205424933781.post-46799559755460672502015-09-29T11:19:59.837-04:002015-09-29T11:19:59.837-04:00I have a question about your white board use.

Are you creating these examples/visuals before class, or are these snapshots of something you create dynamically during the discussion?Josh Brittonhttps://www.blogger.com/profile/00406970770865920678noreply@blogger.comtag:blogger.com,1999:blog-5473916205424933781.post-67023419360467216932015-09-29T11:09:00.067-04:002015-09-29T11:09:00.067-04:00Happy Making!
