Kevin Hoang, a recent contributor from the sunny state of California, recently emailed me with a link to an amazing, and free, online calculator that allows you to really do some neat things. Primarily, it allows you to place generalized functions in and then have the calculator change the parameters of the equation. So, a simple example would be to have a linear function dependent on m and b graphed and then have a slider… Read more »

Posted onLinear Modeling Project – Population Growth – by Steve Weissburg
Posted onSteve Weissburg from Ithaca High School has contributed a really great linear modeling problem for Algebra I. He has students model the populations of India and China over time. Kids collect the data, create a scatter plot, draw a line of best fit, come up with slopes, units, etcetera. Eventually, they predict the year in which India’s population overcomes China’s. To put it mildly, this is a great project. If you want a performance based… Read more »

Posted onStatistical Simulation Programs for Download
Posted onO.k. So, after a bit of legwork, it turns out that it is not hard to post TI-83/84 programs to this site and its not even hard to have you download them. A few days ago, I posted a document detailing three Statistics programs I wrote for the TI-83/84 to do the statistical simulations that are required in the new Common Core Algebra II. I created the simulation programs based on the simulations recommended in… Read more »
Regents Review #9 – A New Regents Review Sheet by Brett Widman
Posted onOur longtime contributory (if a site that is four months old can have those), Brett Widman has given us another great set of Regents Review problems. These are a great collection of problems to either assign in total or pick and choose from. Thank you again Brett for sharing your work with all of us. Algebra 1 RR#7
Fibonacci Sequence Article and Video
Posted onSurely many of you have seen this post from Facebook or other sources, but, just in case, I had to post it. This great article (well worth the read) in the San Francisco Globe tells how the designer, mathematician John Edmark has created sculptures with patterns based on the Fibonacci sequence. As we all know, the Fibonacci occurs a great deal in nature and well describes many recurring patterns that we see in living systems.… Read more »

Posted onStatistical Simulation in Common Core Algebra II
Posted onSo, the statistics standards in Common Core Algebra II specify a lot of use of simulation to establish confidence intervals and other statistical measures of variability. I like these standards, but was having a hard time thinking about how to really fulfill them in a meaningful way. So, I attacked them head on. Based on work from the G.A.I.S.E. Report (google it), I created three programs for the TI-84+ operating system (they work fine on… Read more »
