One of the most common questions we are asked is how our library of digital content supports the Common Core.  The easy answer is that our entire library has been aligned to the Common Core standards, so teachers can find resources related to each standard.  The more complex answer is that there are many pieces of content that can be used in flexible ways to support each individual standard, and it is up to teachers to choose the content that best supports their lesson and their students.

Here are five pieces of digital content a teacher might choose from StarrMatica’s library to support and enhance the teaching of: CCSS.MATH.CONTENT.4.G.A.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
