In recent decades, K-12 math education has evolved significantly, shifting from rote memorization to fostering conceptual understanding and problem-solving skills. Achievement First (AF), a network of public charter schools, exemplifies this transformation through its innovative approaches to math instruction.
In 2019, Alicia Lynch, Senior Director of K-8 Math, a leader on AF’s Teaching & Learning team, began re-evaluating their math curriculum to better align with their vision of an excellent math classroom—one where students deeply engage with and own their learning. This introspection led them to pilot the Context for Learning Mathematics program, which emphasizes problem-solving and critical thinking.
“By teaching in a way that sparks curiosity and confidence, we’re showing kids that they’re capable of solving complex problems. We treat students like real mathematicians, encouraging them to develop ideas and solutions that reflect their unique perspectives,” said Ms. Lynch.
A typical lesson might involve third graders examining an image of a grocery store with fruits and vegetables arranged in arrays. Students discuss the quantity of items and share their problem-solving strategies, engaging in workshops, collaborative work, and presentations. Central to the program is the “Math Congress,” where students discuss and challenge each other’s strategies, fostering a deep understanding of mathematical concepts.

By embracing these innovative teaching practices, Achievement First is not only enhancing math proficiency but also inspiring a generation of confident problem-solvers prepared for real-world challenges.
For Ms. Lynch, the most rewarding part of this work is seeing the “aha” moments in both students and teachers as they embrace new ways of thinking about math. “This program is about changing the way we teach math so that every student feels confident, inspired, and ready to succeed.”
