Mathtrain.TV: Episode 80, The MegaHunk Bar

Monday, November 8th, 2010


This is the story of Rob and the MegaHunk Chocolate Bar that he ate.  But he did not eat the whole thing.  And he did not even start off with an entire bar.

See how to solve this several ways, including visually.  This problem was adapted from my former colleague, Dr. Marcy, and his Marcyworks!

As seen on Mathtrain.TV!

Mathtrain.TV: Episode 55 “Our First Student Screencast from 2007″

Friday, July 24th, 2009

Here is our first official, student-created mathcast from 2007.  It is the early version,which is not edited too much.  It is a bit longer than most of our math videos.

However, 6th grader “Bob” (not her real name) created this on the spot, with no script and no rehearsal.  It was also her FIRST time ever using Camtasia Studio.  Camtasia Studio is the screen recording software we use.  I thought we should release this as an episode.

Lois Smethurst, an educator from Australia, wrote the story below.  See 2 video clips & a little blurb about the “Kids Teaching Kids/Mathtrain” presentation I did at the NECC Conference in Washington, DC.

I was invited to present in the TechSmith booth.  It was an amazing experience.  Yeah, I know.  I spoke way too fast.  But hey, I was excited!
