• # Grade 1 Math Curriculum Grade 1 Math Course Description: In Grade 1, instructional time will focus on four critical areas: (1) developing understanding of addition, subtraction, and strategies for addition and subtraction within 20; (2) developing understanding of whole number relationships and place value, including grouping in tens and ones; (3) developing understanding of linear measurement and measuring lengths as iterating length units; and (4) reasoning about attributes of, and composing and decomposing geometric shapes. (PDE, Standards Aligned System) Our core math resource in grades K-5 is Bridges in Mathematics, which was adopted by our Board of School Directors in the winter of 2018 for implementation in the 2018-19 school year.  "Bridges in Mathematics is a comprehensive PK–5 curriculum that equips teachers to fully implement the Common Core State Standards for Mathematics in a manner that is rigorous, coherent, engaging, and accessible to all learners. The curriculum focuses on developing students’ deep understandings of mathematical concepts, proficiency with key skills, and ability to solve complex and novel problems. Bridges blends direct instruction, structured investigation, and open exploration. It taps into the intelligence and strengths of all students by presenting material that is as linguistically, visually, and kinesthetically rich as it is mathematically powerful." For more information about Bridges in Mathematics visit the Math Learning Center website and for additional information for families, visit the Bridges Family Support page. Family Letter Welcome Standards for Mathematical Practice (Included in all units) Make sense of problems and persevere in solving them. Attend to precision. Reason abstractly and quantitatively. Construct viable arguments and critique the reasoning of others. Model with mathematics. Use appropriate tools strategically. Look for and make use of structure. Look for and express regularity in repeated reasoning.
