A New Approach to Teaching Math
At Atlas, our math program prepares students for success in middle school, high school, and beyond. We believe that for students to thrive, they must be able to make sense of the world through a mathematical lens. Our rigorous instruction balances conceptual understanding, procedural fluency, and real-world application. The Atlas Math Vision aligns with the Missouri Learning Standards, creates coherence across grade levels, and emphasizes key topics within each grade. Above all, we want our students to enjoy math and see themselves as capable mathematicians with the critical thinking and problem-solving skills to solve complex challenges.
Kindergarten–First Grade: Bridges in Mathematics
In Kindergarten and First Grade, we use Bridges in Mathematics, which includes two key components: Number Corner and Math Lessons.
Number Corner is a skill-building program that revolves around the classroom calendar. It provides daily practice designed to introduce, reinforce, and extend skills and concepts related to the critical areas of study at each grade level.
Math Lessons focuses on developing students’ deep understanding of mathematical concepts, proficiency with key skills, and ability to solve complex problems. This instructional block features a combination of whole-group, small-group, and independent activities that are problem centers. Together, these components help students become confident, capable, and curious mathematicians.

Grades 2–5: Illustrative Mathematics (IM)
In Grades 2–5, we use Illustrative Mathematics (IM), a problem-based curriculum that builds deep understanding through reasoning, collaboration, and discussion. Students learn by solving real-world problems, explaining their thinking, and listening to others’ ideas. They practice justifying their reasoning and considering different perspectives—skills that help them grow not only as mathematicians, but also as thoughtful, collaborative learners.
