I would be genuinely confused about whether to put Jack on the 12th or 13th square (assuming that the interface doesn't allow any other options).<br /><br />But I'm not so sure I agree about Kendrick's conjecture. I think this problem format is an interesting attempt to get at Grade 4 reasoning skills. The student who can both find a confirming instance of Kendrick's statement and also find a counterexample shows more reasoning ability than the student who can only do one of these. And finding a counterexample is proving something (namely that a statement is not true).<br /><br />I don't think the word "support" has the specific mathematical meaning you attribute to it here; in fact most mathematicians would use the word the way it is used here, namely in the sense of confirming empirical evidence as distinct from mathematical proof. It's important for students to understand the difference between the two, and also to understand that a statement can have some confirming empirical evidence but still be false. A student who doesn't understand this point could have a harder time with this question, which means it could make it a good assessment. I'm not sure about this, but it seems worth trying to me.Bill McCallumhttps://www.blogger.com/profile/09647093331377576865noreply@blogger.comtag:blogger.com,1999:blog-6172532982347376290.post-8053792906330370172013-07-24T23:03:16.942-04:002013-07-24T23:03:16.942-04:00This page answers a mystery of how CCSS can simult...This page answers a mystery of how CCSS can simultaneously be a grade or more down level from California 1997 and cause so much difficulty with test completion. Question 16 above explains it all. Supposedly a 3rd grade problem easily solved with what was 4th grade algebra in the old standard (now moved to 7th grade with CCSS). This is a cruel pointless joke. It's almost like testing a contractor to build a house without a hammer or screwdriver. I'm wondering what's going to happen when my tutor-trained 5th grader does solve these problems with algebra. Is he going to me marked wrong for not explaining the answer the same way as his algebra-naive classmates?Unknownhttps://www.blogger.com/profile/09852051001772361806noreply@blogger.comtag:blogger.com,1999:blog-6172532982347376290.post-18909496144624738902013-06-28T08:39:48.919-04:002013-06-28T08:39:48.919-04:00I work at a Math learning/tutoring center.

These problems appear to me to be beyond the capabilities of the current grade level I have observed.<br /><br />I understand and applaud the CCSS having higher expectations. My worry is that teachers will not have adequate training and time to improve students to these levels by the time CCSS is in full implementation.<br /><br />Also, the 800-lb gorilla in the room is what happens with students whose test scores and grades are good/adequate who will now be adjudged as "Not Proficient" based on the CCSS' higher expectations.Mark Ahrenshttps://www.blogger.com/profile/03427710952693857226noreply@blogger.comtag:blogger.com,1999:blog-6172532982347376290.post-53430262365183953962013-06-27T11:04:45.241-04:002013-06-27T11:04:45.241-04:00Thank you so much for this thorough examination. ...Thank you so much for this thorough examination. I took the 3rd grade test and actually had to drag chairs over and was like, huh? Is this the robust rigor they were talking about?Michele Shttps://www.blogger.com/profile/15061520456909635254noreply@blogger.com
