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 our library to support and enhance the teaching of CCSS.Math.Content.1.NBT.B.2(A,B,C)  Understand that the two digits of a two-digit number represent amounts of tens and ones.

You could use this simple activity with students to help them visualize groups of ten.  This game challenges students to count the number of seeds in the field before they disappear.  They have to count by tens and ones because the seeds disappear too quickly to count one at a time.  3 disappearing speeds are offered.  (You must be a StarrMatica member and be logged in to access this resource.)
