3 Elementary Math - Grade 2 3 STATEMENT OF PURPOSE The Common Core State Standards for Mathematics challenges us to ensure focus and coherence in our mathematics curriculum across all elementary grade levels. This curriculum guide aligns these standards with our resources to ensure high achievement for all students. Coherence is supported by the alignment of the curriculum, instruction, and assessments. The repeated Domains within the CCSSM, progress through the elementary grades to allow for developmentally appropriate attainment of learning outcomes. The CCSS Matrix for each grade level can be referenced for a visual representation of this idea. The curriculum s suggested pacing allows for the important balance of developing conceptual understanding and procedural skills. Instructional decisions are guided by the use of Board approved resources, problembased learning, and real-world applications that incorporate technology and 21 st Century Skills. Various forms of assessment are used to determine understanding of concepts and mastery of skills. This data is analyzed to inform professional development needs, revision of curriculum, as well as immediate targeted instruction for student needs. Focus is provided by explicitly naming the topics on the Overview page and providing the Unit Objectives/Enduring Understandings, key ideas, and skills on the curriculum pages. Please note, key ideas are separated from the skills by columns, but the students learning experiences are not separate. Students develop deeper understandings of mathematical concepts because they spend time thinking like mathematicians and are involved in the Standards for Mathematical Practices. The Standards for Mathematical Practices do not serve the same purpose as the Common Core State Standards and are not organized like them. The Common Core State Standards for Mathematics include these separate eight practices for the mathematics educators to develop these competencies within their students over time. The opportunities for modeling and developing these practices in the classroom arise when the CCSSM uses the term, understand in a standard. Students can gain better understanding of a concept when engaged in these practices as follows. Standards for Mathematical Practice 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. This curriculum guide has been developed to address the rigor in the Common Core State Standards for Mathematics and the relevance in the 21 st Century Skills, including technology as a tool for learning and applying new knowledge. Future revisions of this guide will be informed by new understandings of the CCSSM, reflections on instruction, and data collection from pacing and assessments.
