Video Tutorials
Sometimes, adults need a little refresher on math content to be able to make all of the connections and support student learning. In addition to the math models and strategies videos, the websites below offer some support.
Khan AcademyKhan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace  free! This site is best for a quick, general refresher of the mathematics involved in K8 education.
To access the videos and practice problems, select a grade (38+) from the math menu, and create a free account (parent or student) to save your progress. For material below grade 3, click early math. "Uncle Sal" and his team offer video snap practice problems on major content areas. A sample screenshot from an 8th grade video tutorial on solving equations with variables on both sides of the equation.

The Art of Problem SolvingThe Art of Problem Solving offers an archive of video tutorials about middle school and math challenge topics. There are many videos delving into PreAlgebra (Gr. 6  8), Algebra (Gr. 7 & 8), Counting and Probability (Gr. 7), as well as tutorials about the math competitions MathCounts and AMC. The videos feature Richard Rusczyk, the founder of the Art of Problem Solving.
To access the videos, go to the Video Tutorial page on the site, and view the list of videos by book (e.g. PreAlgebra) and chapter. A sample screenshot from a PreAlgebra video on finding the sum of square roots.

LearnZillionLearnZillion offers video tutorials on the the Common Core Standards for grades 2  8. Because it is organized by grade and then by standard, it is a little more difficult for the average parent to navigate, however the videos are of higher quality than the Khan Academy ones.
To access the videos, create a free teacher account, and then select the grade level. From there, click on "math" and a specific domain (OA = operations and algebraic thinking; NBT = numbers and operations in base 10; NF = numbers and operations with fractions; G = geometry; MD = Measurement and Data). A sample screenshot from a 5th grade Operations and Algebraic Thinking video.
