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 multiplication and division and strategies for multiplication and division within 100;
  • developing understanding of fractions, especially unit fractions (fractions with numerator 1);
  • developing understanding of the structure of rectangular arrays and of area; and
  • describing and analyzing two-dimensional shapes.
