Got Fractions?

Many of us had the same experience in school when learning fractions.  We just had to memorize the procedures to add, subtract, multiply and divide them, without any understanding of why or how the steps made sense.  Most of the time, I couldn't even figure out when I would need to use the calculations... besides in my math class.

As teachers we have to learn the concepts that were missed in our own education to be better prepared to teach our students.  Thank goodness for resources like this from Illustrative Mathematics.  It's a seven part video on the progressions of skills needed to teach/learn the Common Core State Standards in fractions.  Thank you, thank you, thank you, Illustrative Mathematics!
