## Math Expressions Links to Learnzillion Videos

The purpose of aligning the Math Expression text to the Learnzillion videos is to provide a resource for students, parents, and teachers.  Students, parents, and teachers can quickly find Learnzillion math videos to supplement the Math Expressions text.  Math Expressions and Learnzillion are different resources that both support the Utah State Core Standards.  Not every lesson from Math Expressions and every standard from the Utah State Core is supported by a Learnzillion video lesson as of this time.  More support content will be added as it becomes available.
