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.

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 professional development video clip shows students engaged in the Common Core Practice Standard #3—Construct viable arguments for conclusions reached and critique the reasoning of others. In this lesson, learners work in groups to discuss and revise their estimates of how many seeds are in a small pumpkin. Additional resources include a video transcript, teaching tips, and a link to a professional development reflection activity based upon the video.

This place value and problem solving lesson focuses on forming 3-digit address numbers to meet specific requirement. The lesson provides an opportunity for learners to use the problem-solving strategies of looking for patterns and establishing an organized list. Students also learn that careful reading of information and understanding of mathematical language are important to finding appropriate solutions.

This webpage contains a link to a downloadable Geometer's Sketchpad activity that familiarizes students with inequality signs (> and <) and introduces the use of the variable x to represent an unknown value. Students are challenged to deduce a number by collecting and analyzing clues that narrow its range of possible values in the fewest guesses. The page also includes a three-minute instructional video and downloadable PDFs of teacher notes and student worksheets. This activity opens on Geometer's Sketchpad as well as on iOS with Sketchbook Explorer (cataloged separately).

This Flash applet is an interactive version of the classic game that develops number sense and strategic thinking. The computer generates a random secret number. The user makes guesses, taking advantage of the higher or lower clues provided, until the number is discovered. The goal is to find the secret number with as few attempts as possible. Three levels allow the user to adjust the range of possible numbers: up to 100, 500, or 1000.

This webpage offers a variety of games which develop strategic thinking, analytical skills, and basic number skills. Three pdfs provide instructions and materials for sets of games played on reusable boards, on consumable sheets, and with number cards. The only other materials required are counters/chips, dice, and pens/pencils. The site also includes instructions for games that require only counters or paper and pencil. A short article describes the rationale for using such games in the classroom and offers suggestions for organizing and managing games and for maximizing their benefits.

This blog entry discusses the difficulties of keeping students with learning disabilities at pace with their peers. Angelia provides a solution that helps her, which involves progress monitoring through weekly review tests. She provides the reader with an example of one of these tests (which checks for operation choice in word problems) and three examples of her progress monitoring data sheets.
