    Child Working on math Portland Public Schools Adopts a New K- 5 Math Curriculum
    New K-5 math materials reached classrooms fall of
    2011. On Monday, February 7, 2011, the PPS school
    board unanimously approved the recommendation to
    adoption Bridges in Mathematics, as the core math
    curriculum for grades K- 5. This action is a result of an
    evaluation of all state approved curriculum that was
    conducted by the district CMAAC (Curriculum Adoption
    Advisory Committee) over an 18-month period. The
    district CMAAC was comprise of teachers, specialist,
    and parent/community members. The last adoption of
    K-5 math curricula was in 1998.
    Bridges is a full elementary school curriculum that provides tool, strategies and the materials that teachers need to implement state and national standards.
    The funding for the core curriculum materials is provided under the November 2006 Local Option Property Tax Levy.

    Overview of Bridges In Mathematics

    The Getting Started Guide helps teachers implement Bridges effectively. It provides an overview of the program, planning and organizing tips, evaluation information, and more.

    Bridges Teachers Guides provide all the instructional information needed to implement lessons, activities, assessments, and homework assignments. An introduction for each unit includes the big mathematical idea, a planner, materials list, and best practice tips. Related items include Home Connections, a collection of take-home assignments, and Technology Connections, a series of technology-based activities.
    The structure of the Bridges curriculum

    Units - Core Math instruction
    • Each unit focuses on specific mathematical topic, or a few related topics and is comprised of between 15 and 30 hour-long sessions.
    • A session may contain any combination of three different kinds of activities:
    Problems and Investigations teach key skills and concepts in the context of problem solving and skill building. Students are involved in whole group and partner work, as well as independent work.
    Work Places are games and /or activities that provide practice opportunities. Students work with partners or alone. Most involve concrete or visual models and paper and pencil recording
    Assessments most assessments require students to answer open-ended questions and to explain their thinking. Assessments take no more that 30 minutes.

    * Each unit also includes weekly Home Connections, assignments that students complete independently at home or outside of the math class.

    The Number Corner Teachers Guide contains a collection of daily workouts for each month of the school year. These 15–20 minute workouts revolve around the classroom calendar and allow students to solidify skills and gain repeated exposure to fundamental concepts. Additional information includes a monthly planner, materials list, assessment checkups, and other support materials.

    Elements of Number Corner

    Each day students spend 15 – 20 minutes completing one or two of the Number Corner workouts. Most workouts are whole group, although students are given time for independent practice in their Number Corner Student books. There are six different workouts in the Number Corner. Examples from grade 3.

    Calendar Grid develops algebraic thinking (spatial and numerical patterns) and generalizations about number
    Number Grid develops number skills and computational skills by using a variety of 10 by 10 grids… 1-100, 101-200, 10 – 1000….
    Magnetic Board resource for students to share their strategies and “talk” about math with partners or whole group.
    Clocks, Coins, and Bills activities or games that focus on time and money. Students practice measuring elapsed time and determining sums and differences with money.
    Computational Fluency these activities and games focus on practicing strategies through a variety of games and worksheets.
    Data Collection focuses on collecting, presenting, and analyzing data.

    Assessment and Support Activities are also found in Number Corner. There are baseline assessments and quarterly checkups. Check ups are intended to examine a students’ growth in a variety of strands over time. Support activities are recommended based on student performance on the check ups. These activities are recommended for use in addition to the core math instruction.
