Let kids figure it out for themselves, given a variety of concepts and connections like the ones you mention here. <br /><br />What about lines where you can't see them cross any lattice points? Lines with irrational slopes - Can you graph such a line? Including questions such as this one really clarifies the whole topic.Julia Tsyganhttps://www.blogger.com/profile/04354702485097004759noreply@blogger.comtag:blogger.com,1999:blog-5964889903484807623.post-68131011035946262772010-12-15T10:03:00.849-08:002010-12-15T10:03:00.849-08:00I'm not trying to pit one against the other. ...I'm not trying to pit one against the other. I just think that the visual gives context to the symbolic manipulation. We are really focusing on multiple representations this year and I think that this helped.

Others like to make t-charts and see how the numbers make patterns and play out. Others still understand the symbolic manipulation best.<br /><br />I guess I'm just saying not to discount the previous ways you were doing it.CalcDavehttps://www.blogger.com/profile/14039458440867020542noreply@blogger.com
