K-12 Mathematics

  • The K-12 mathematics program within Southern Lehigh School District will provide opportunities for all students to develop the ability to independently apply mathematical knowledge and skills to real-world situations. A robust and coherent curriculum will prepare students to think and reason mathematically while requiring them to demonstrate a deep understanding of mathematics. Students will develop critical thinking, problem solving, innovation, collaboration, and communication skills. A focus will be placed on using mathematics as a key to understanding the world, in order to meet the challenges of a dynamic society.

K-12 Mathematics Philosophy

  • Mission Statement for K-12 Mathematics:
    Empowering students to problem solve, innovate, and communicate mathematically to understand the world around them and seize tomorrow’s opportunities.

    Guiding Principles for K-12 Mathematics:
    Students will be able to...

    • be flexible mathematical thinkers by generating and connecting various mathematical representations and concepts.
    • look for, recognize, and use structure and patterns.
    • apply and transfer mathematical knowledge, skills, and strategies to new and real world situations.
    • reason abstractly and quantitatively.
    • engage in mathematical discourse and communicate thinking using appropriate mathematical language and vocabulary.
    • make sense of problems and persevere in solving them.
    • reflect and revise thinking to ensure reasonable solutions.
    • model with mathematics.
    • attend to precision.
    • select and use appropriate tools strategically in order to deepen understanding of concepts.
    • construct viable arguments and critique the reasoning of others.
    • demonstrate both a conceptual understanding of mathematics and procedural fluency

    Best Practices for K-12 Mathematics:
    Teachers will...

    • promote the joy, wonder, and beauty of mathematics.
    • develop a learning environment that promotes productive struggle, risk taking, self-efficacy, and resilience.  
    • use and promote the use of a variety of mathematical representations (i.e. concrete, representational, abstract, verbal, and contextual).
    • use goals to engage students in discussion about what they are learning and why they are learning it.
    • use focused and leveled questioning to engage students in higher order thinking.
    • provide opportunities for students to engage with authentic problem solving and challenging tasks.
    • provide opportunities for students to acquire conceptual and procedural knowledge.
    • provide opportunities for students to construct knowledge through mathematical discourse .
    • provide opportunities for students to make sense of problems, analyze their thinking, and revise their work.
    • provide opportunities for students to make connections with prior knowledge and build upon current understanding.
    • help students develop metacognitive awareness.
    • provide students with mathematical tools (including manipulatives), model their use, and encourage students to select appropriate tools strategically.
    • provide opportunities for students to develop number sense.
    • reinforce the use of precise mathematical language and vocabulary.
    • help students embrace and learn from their mistakes.
    • provide differentiated classroom instruction driven by assessment to meet the needs of all learners.
