Modification to SBG for second semester

I gave a Google survey at the end of first semester, several students mentioned that the 4 point grading scale that I was using seemed a little goofy.  One mistake put you down to a 75 and after the standard had moved to the 5 point maximum, that was a 60.  I started off by using the point system outlined in this blog post by Dan Meyer

I thought that the number of standards assigned each quarter would balance that off, but I do still think one small mistake could have too much of an impact on the grade, so I've decided to make each standard worth 9 points instead of 4.  If a student gets 9/9 twice, they receive the full credit of 10/10.  Also, second semester involves some complex tasks, so I'd like to have more points to work with for partial credit.

Twitterfeed is how I connect my Blogger posts with Twitter.  It stopped working, I'm pretty sure that's because I changed my Twitter password recently.  I've tried to reauthorize it, hopefully this post shows up on Twitter...


This isn't particularly new, but I just found the part of it that has Common Core questions.  There is a charge for it, but there are nice multiple choice problems arranged by Common Core standard.

Statistics Unit

We are approaching the end of first semester and we are finishing our first ever Common Core Statistics unit.  We covered dot plots, histograms, measures of central tendency, box and whisker plots and standard deviation.  We found that the students were familiar with most of this information except for standard deviation.  Next year, I will go through some of the basic concepts quicker and I will spend more time on analyzing data.   I'm thinking more analysis of outliers and more study of different types of distributions (normal and otherwise).  Here's links to some activities that I found helpful
