Solid circle. Find an excuse to do the graphing a week or two in advance. <BR/><BR/>Solid circle means the number is included. We can circle a number just to point it out (I do that for zero on a bunch of number lines).<BR/><BR/>Then, when the inequality comes, when I model board work I always start with an open circle. "Should we include 7?" And if they respond yes, fill it in.<BR/><BR/>I have much better luck than I used to.<BR/><BR/>JonathanAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-30226356.post-23723804195654894022009-04-05T15:21:00.000-07:002009-04-05T15:21:00.000-07:00I just checked out your inequalities lesson last w...I just checked out your inequalities lesson last week and I really like the bubbled choices for inequalities, seems like a helpful way to get kids to notice the sign rules. I actually found myself starting a lesson on absoluate value inequalities with some fill in the blanks to direct the thinking a little bit more. Stuff like<BR/><BR/>|5 - 3| = ?<BR/>|3 - 5| = ?<BR/>if |x| = 5, then x = ___ or ___<BR/>if |x-2| = 4, then x = ___ or ___<BR/>if |x - ?| = 5 and x = 3 or -7, then ? must be equal to ____.Nickhttp://www.ateacher.org/blog/noreply@blogger.com
