Second grade uses Pearson’s Investigations math program. It focuses on helping students make sense of mathematics in meaningful ways, and learn that they can be mathematical thinkers. Investigations’ areas of concentration include computational fluency with whole numbers as a major goal. This program is rich with content, and emphasizes reasoning about mathematical ideas. Individual lessons engage a wide range of learners by design and meet the needs of students who learn in different ways. Please contact your chid’s classroom teacher with specific unit questions.
