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.3.G.A.1

Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

Pattern Blocks Shape Tool

A teacher could use this virtual manipulative with students on an interactive whiteboard and choose relevant shapes to start a discussion about how one shape can have different names. (square, quadrilateral, polygon, parallelogram)

Exploring Shape Classification

A teacher could use this activity to challenge students to sort shapes into four different diagrams based on their characteristics. (Choose the Shape Classification Tab.)

Carroll Diagram Shape Sort

A teacher could use this activity with students to encourage students to think about multiple categories a shape could belong in as they sort shapes into a Carroll Diagram.

Shape Guess

A teacher could use this activity to challenge students to find all of the shapes that match the given characteristic.

Classifying Polygons

A teacher could use this resource to challenge students to sort shapes into a triple venn diagram without knowing the categories.  Then students are asked to figure out the categories.
