Building Mathematical Thinkers

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.

As educators, you strive to make well-informed curriculum adoption decisions. We fully support this goal and invite you to read What you need to know about Bridges.

Visual Models

Seeing, touching, and sketching ideas create pictures in the mind’s eye, helping learners construct, understand, and apply mathematical ideas. Bridges incorporates increasingly complex visual models, including the Number Line and the Array models, in a coherent framework across the curriculum.

Professional Development

Our professional development workshop leaders use firsthand knowledge and experience to present powerful methods for teaching mathematics and model these strategies in their instruction.

This two-day summer workshop brings our workshop leaders to your district. They work face-to-face with your classroom teachers, walking through unpacking of the curriculum components and exploring math practices in the contexts of the models and strategies. Each workshop is packed with information, pedagogy, and hands-on activities. Teachers explore resources, dive into Number Corner, and do math that resembles a Bridges classroom.

Bridges Getting Started workshops are scheduled either by grade-level bands, such as K–2 and 3–5, or are grade specific. A maximum of 30 participants is allowed in each session, but multiple sessions can be scheduled.

“We thoroughly enjoyed having you set such a wonderful tone for our group. Thank you for sharing your expertise, bringing laughter to the room, and cultivating confidence for our teachers.”

Many students, especially my ELL students, are developing a stronger sense of number using the visual ten-frames and finger models from Bridges. These strategies are providing successful concrete to representational forms for students.

Kindergarten teacher — Hood River, OR

I wanted to let you know how much my students and I enjoyed the "quick sketch" model for multiplying larger numbers. It is nice to be able to put a visual in student's hands to help them
understand a normally complicated process. 

Grade 4 teacher — Ft. Bridger, WY

Bridges promotes a deeper level of understanding and encourages higher order thinking.

Grade 3 teacher — Oklahoma City, OK

Bridges met the needs of both my high and low students. The kids were challenged and really enjoyed math -- even those who started the year hating math. And, my students did well on the state math assessment.
