 Laredo Middle School
 Math
Math Department Vision

The goal for our Laredo students is that they leave middle school with a strong foundation in mathematics and an understanding of its relevance in their lives. We want to make sure that they are prepared to be successful in their future mathematics studies, as well as to be knowledgeable about mathematics in their world. Mathematics is essential for all students as they grow to understand their world and become productive citizens. Mathematical models explain, celebrate, and analyze the world around us; from economic models on the stock market to musical models of symphonies, our world is mathematics. We want students to leave Laredo as confident problem solvers ready to tackle whatever comes their way.
In alignment with the National Council of Teachers of Mathematics, this means the math department at Laredo will help students with:
 Developing their college and career readiness
 Deepening understanding and critiquing the world using mathematics
 Experiencing joy, wonder, and the beauty of mathematics
