The Wall Street Journal on adding fractions. Why are we interested?

From the Wall Street Journal on October 2, 2013.  Read the whole article, but here are a few highlights.
Many students cruise along just fine in math until fourth grade or so. Then, they hit a wall— fractions.
The wall is about to get taller. With mastery of the topic seen as a crucial stepping stone to progressing in math, federal standards are stepping up emphasis on fractions starting in third grade. National tests show nearly half of eighth-graders aren't able to put three fractions in order by size. 
The key is lines and not pies.  Robert Bennin, our iMentorCorps resident math guru, hit on this a few months ago.  He and the team prepared the video below.  Don't worry about the 'iMentorCorps Confidential' title at the beginning.  We're working on a new series of videos, so you're getting a sneak peek into some of our latest work.

The Wall Street Journal article noticed this as well.
Ryan Spence, a technology-integration specialist for Propel Schools, a charter-school operator based in Pittsburgh, says fourth-graders can learn the basics quickly by playing a computer game with number lines, Battleship Numberline...
Lines, not pies.  Sound simple?  It helps students better grasp the important concept of fractions.

Let us know what you think of our approach.
