It has kids set up equations as two sides of a balance scale and solve to find out how much each x must weigh to balance. Checks are built in to each problem so students can show how much weight they'll end up with on each side.Sarahnoreply@blogger.comtag:blogger.com,1999:blog-10220498.post-23257532507321638812009-12-21T09:05:39.352-06:002009-12-21T09:05:39.352-06:00It's not just in the ninth grade.

And, like you, at our school we're really trying to get them to see past the end of the pencil.<br /><br />The few occasions we've used the incorrect (and sometimes correct solutions--they have to tell us which) have been truly eye-openers. They seem to "get" it better when they are working with real-world problems. For instance, is that a reasonable estimation? How did she get such an answer?<br /><br />Or perhaps it's just nice for them to see somebody besides themselves moving the decimal place two times instead of one.<br /><br />The Algebra 1 students, initially resistant to finding the error, (probably because the properties were still new), find it more of a challenge. They are required to be more explicit mathematically in their answers.Grandmama Sarahhttps://www.blogger.com/profile/14582585550916999427noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-79680544663956651052009-12-10T17:46:09.836-06:002009-12-10T17:46:09.836-06:00Ooh, I like the telling them of the number of erro...Ooh, I like the telling them of the number of errors at the outset.

She would tell them "there are x number of errors in how this problem has been solved. Find and circle them, and work out the correct solution with the errors corrected". It worked well to show their understanding of concepts and helped them check their own work for mistakes in the future.Jessicahttps://www.blogger.com/profile/07008284686488859024noreply@blogger.com
