Big Ideas Diamond - Line Break


No other authorship team in the industry provides the balance of classroom experience and mathematical expertise that the Big Ideas Math program authors bring to the table. Dr. Ron Larson and Dr. Laurie Boswell began writing together in 1992. Since that time, they have authored over four dozen textbooks. In their collaboration, Ron is primarily responsible for the Student Edition while Laurie is primarily responsible for the Teaching Edition.

Laurie's Notes

Balanced Approach to Instruction

The Big Ideas Math program follows a balanced instructional approach. The program balances conceptual understanding with procedural fluency, as research shows that students benefit from equal exposure to discovery learning and scaffolded instruction.

Each section in the program begins with a discovery exploration that encourages conceptual understanding. These provide students with the opportunity to explore, question, explain, and persevere as they seek to answer questions that encourage abstract thought.

Each exploration is then followed by a scaffolded lesson. These lessons give students the opportunity to develop procedural fluency and to use clear, precise mathematical language. These lessons also give teachers opportunities to use class discussion, flexible grouping, and other delivery methods in their classrooms.

Real-life applications are utilized throughout the program. These applications are opportunities for students to connect classroom lessons to realistic scenarios, and assist teachers with turning mathematical learning into an engaging and meaningful way to explore the real world.

The Mathematical Practices and Proficiencies are woven into every chapter. In addition, Show and Grow, Apply and Grow, Try It, or Monitoring Progress problems allow students to practice and sharpen their skills as they work toward mathematical understanding.

Personalized Learning with Complete Teacher Support

The Big Ideas Math program offers teachers and students a number of tools to personalize and enrich their classroom experience. Teachers can use Laurie's Notes, the Dynamic Classroom, and the Answer Presentation Tool on a daily basis. Students can use the online Lesson Tutorial Videos which are valuable for students who miss a class, need a second explanation, or just need some help with a homework assignment. Big Ideas Math completely supports the 3-Tier Response to Intervention Model, so the program can be customized for every level of learner.

Teaching Edition with Laurie’s Notes

The Big Ideas Math Teaching Edition is unique in its organization. Throughout the book, master educator Laurie Boswell shares insights on Learning Progressions and Mathematical Practices and Proficiencies.

Laurie includes best practices, motivational techniques, connections to previous learning, support for the Mathematical Practices and Proficiencies, and closure opportunities for the entire Student Edition. The Teaching Edition also provides Differentiated Instruction, Response to Intervention, and English Language Learner support.

Editable Online Resources

Complete and editable Lesson Plans and Pacing Guides are available online for every lesson in the program to provide teachers with support for planning.

Differentiated Instruction

Through print and digital resources, the Big Ideas Math program completely supports the 3-Tier Response to Intervention model. Using research-based instructional strategies teachers can reach, challenge, and motivate each student with high-quality instruction targeted to individual needs.
