Your idea is excellent; the difficulty is something that not sufficient people are speaking intelligently about. I'm very glad that I stumbled throughout this in my search for something regarding this. <a href="https://online-casinos.us.org" rel="nofollow">real money casino</a>raynnowui21https://www.blogger.com/profile/09781471042378470018noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-31823086107063014042014-12-19T19:10:19.080-06:002014-12-19T19:10:19.080-06:00I read, enjoy and learn from your blog.

Now, I use those at the start of the year with 7th graders or with kids coming for help after class. <br /><br />With older students, I try to focus on fast rules: <br />1. Look at the symbols (or implied symbols) in front of the digits. Are the symbols the same or different (ie, -2-5 both have minus signs in front, whereas 3-7 have different signs).<br />2. If the signs are the same, add the digits and keep the sign.<br />3. If the signs are different, subtract the smaller digit from the larger. Keep the sign from the larger digit. <br /><br />It's such a battle!atclasshttp://atclass.wordpress.com/noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-22701209752787290602010-07-05T08:02:57.680-05:002010-07-05T08:02:57.680-05:00You would HOPE that the students would have this s...You would HOPE that the students would have this skill down before the 7th grade (or high school), but sadly, many still struggle with it.<br /><br />Ms. CookieShireen Dadmehrhttps://www.blogger.com/profile/16282965851939089408noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-79392160316158875912010-07-04T23:13:50.000-05:002010-07-04T23:13:50.000-05:00Is "7th graders" a typo?

I'd never thought about it before, just knew the rule, but our conversation made me come up with my own reasoning (which is probably not new).<br /><br />If you think of multiplication as repeated addition, then say -3 * -5, means you are "adding" -5 three times in the "opposite" direction, or you're subtracting -5 three times. <br /><br />So going back to the "star" model here. You start at 0 (facing right), and you're "subtracting" -5 three times. So 0 - -5 - -5 - -5. The negative on the 5 makes me turn 180 degrees to face left, and the subtracting moves backwards (so to the right). Boom, 15.<br /><br />Ms. CookieShireen Dadmehrhttps://www.blogger.com/profile/16282965851939089408noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-7408689602502806752010-06-19T01:54:50.441-05:002010-06-19T01:54:50.441-05:00Not a bad idea - I tend to use temperature as a co...Not a bad idea - I tend to use temperature as a context for integers, so a vertical number line would suit my students better. <br /><br />Any ideas for models / contexts for negative times negative?Anonymousnoreply@blogger.com
