The Year at a Glance provides an overview of the mathematics content taught in the course.

Bridges in Mathematics, second edition, is a comprehensive K–5 mathematics 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, and taps into the intelligence strengths of all students by presenting material that is as linguistically, visually, and kinesthetically rich as it is mathematically powerful.

Instructional time should focus on
  • developing understanding of addition, subtraction, and strategies for addition and subtraction within 20;
  • developing understanding of whole number relationships and place value, including grouping in tens and ones;
  • developing understanding of linear measurement and measuring lengths as iterating length units; and
  • reasoning about attributes of, and composing and decomposing geometric shapes.
