This 51-page pdf document demonstrates the connections between the CCSS content standards and the mathematical practice standards. It is a compilation of research, standards from several states, instructional strategies, common misconceptions, and examples for each standard at the grade 2 level. It is intended to help teachers understand what each standard means in terms of what students must know and be able to do. Additional flip books are cataloged separately for grades K-1 and 3-5.
Instructional Strategy, Reference Materials
This web page provides links to resources aligned to the CCSS that guide and support second grade mathematics teaching and learning. Tasks developed by the Mathematics Assessment Resource Service (MARS), Problems of the Month, (POM home page is cataloged separately) and videos of public lessons and number talks developed by the Noyce Foundation are included. The tasks were designed to measure students’ ability to solve non-routine problems, explain and justify their solutions, and promote high level thinking skills. They include the scoring rubric, student responses, and discussion of student understanding and misconceptions. Resources are listed for specific grade 2 standards and are also organized by progression for an alternate search route.

This page hosts a collection of geometric tasks in pdf format that are aligned to the CCSS standards 2.G1 through 2.G3. It also has links to supplementary literature and learning materials.
Activity, Problem Set, Image Set
This interactive Flash lesson helps students to visualize the faces and edges that make up cubes and to distinguish cubes from other shapes. A pdf teacher guide is available at MathActive Lessons for Grades 3-4 (cataloged separately), which also includes links to unvoiced, Navajo, and Spanish versions of the lesson (see #1, 3, 4).

This interactive Java applet gives students practice in sorting attribute blocks by color, shape, or size. In each problem students are presented with a set of objects that share a common attribute, and they must identify objects from another set that have the same attribute. Students can check their solution, and have another try or request a new problem. Teacher information about the blocks and their classroom implementation is included.
Activity, Interactive Media
This interactive Java applet helps students learn about sequences and patterns through analysis of attributes. The user analyzes the existing pattern and must complete the "train" by dragging the appropriate shapes into place. The user is required to discern which attribute is used to create the pattern (color, shape, or number) as well as determine how to extend it.
Activity, Interactive Media
This interactive Java applet allows users to sort shapes into a bar graph based on the attributes of shape or color. An optional scoring feature allows users to keep track of the number correct.
