  • Overview

    District 25 uses Math in Focus for Kindergarten through 5th grade students.  This curriculum utilizes a concrete, pictorial, and abstract approach that focuses on problem solving and conceptual understanding of math concepts. In middle school, 6th through 8th grade students participate in the Big Ideas curriculum that focuses on problem-solving, real-life application, and conceptual understanding through a mix of exploration and practice. Starting in 4th grade, District 25 offers advanced math courses for students who demonstrate a need for grade-level accelerated content.  



    Illinois has adopted the Illinois Learning Standards, which are based on the Common Core State Standards.  District 25 uses the Illinois Learning Standards to align curriculum and inform instruction.  By emphasizing depth over breadth, the Illinois Learning Standards ensures that students have comprehensive understanding of key concepts. Additional information can be found on the Illinois State Board of Education website.  



    The Math in Focus program strives to develop conceptual understanding with the goal of content mastery.  Concepts are taught moving through a sequence of concrete to pictorial to abstract.  Concrete learning happens through hands-on activities with math manipulatives, such as counters, coins, number lines, or base ten blocks.  Pictorial learning uses pictures, drawings, or other forms that illustrate the concept with something more than abstract numbers.  Finally, abstract learning requires students to use numerals, strategies, and problem solving methods to solve problems. Math in Focus is a research-based program that focuses on classroom learning, discussion, and practice.  It strives to balance conceptual understanding, visual learning, and problem solving.  


    The Big Ideas Math program, written by Ron Larson and Laurie Boswell, and published by Houghton Mifflin Harcourt, utilizes a research-based, balanced instructional approach that includes both discovery learning and scaffolded lessons.  Big Ideas Math is dedicated to the balanced approach to instruction. Activities and Explorations involve student-directed discovery learning, allowing students to develop conceptual understanding. The discovery learning is followed by scaffolded instruction, giving students the opportunity to utilize clear, precise mathematics language, and structure.
