The Achievement First Elementary Math Program

The Achievement First elementary math program aims for students to build a strong foundation in mathematical understanding, develop confidence as mathematicians, and experience joy in solving problems and exploring mathematical ideas. Students learn to think critically, communicate their reasoning, and apply their learning to meaningful situations.

Our program is grounded in several core components:

• Core Instruction: Students develop strong conceptual understanding, procedural fluency, and mathematical reasoning aligned to grade-level standards.
• Problem Solving: Students engage in meaningful mathematical tasks that promote critical thinking, perseverance, and multiple problem-solving strategies.
• Cumulative Review: Students regularly revisit previously taught concepts to strengthen retention and deepen understanding.
• Small Group Instruction: Students receive targeted support and enrichment to ensure all learners can access grade-level content and reach their fullest mathematical potential.
• Diversity, Equity, and Inclusion: We strive to ensure our curriculum, instructional practices, and student experiences affirm identity, foster belonging, and reflect diverse perspectives.
