The site is organized by grade and activities are aligned to the Common Core State Standards (CCSS). Within the navigation the activities are further classified under headings such as Operations & Algebraic Thinking, Number & Operations in Base Ten, Measurement & Data, Geometry. You can drill down further to a specific standard for the grade. Clips can be categorized as SUPPORTS, MEETS or EXTENDS a standard so teachers have flexibility to select activities that suit the mixture of student abilities in their classroom.

MEETS 1.G.A.1: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
SUPPORTS 1.G.A.1: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
EXTENDS 1.G.A.1: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

SUPPORTS 1.G.A.2: Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

SUPPORTS 1.MD.A.2: Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
SUPPORTS 1.MD.B.3: Tell and write time in hours and half-hours using analog and digital clocks.
