A task that addresses standard 4.NF.A.2 that was created as part of the Adapting Instructional Materials Project.

Many districts and schools are waiting until curriculum aligned to the Common Core State Standards for Mathematics comes to the market before buying new materials. Teachers are left to find ways to adapt their current curriculum to meet the Standards, which can be a daunting task. The Adapting Instructional Materials Project evolved to fill this need. The project worked with two small New York districts to adapt their fractions teaching materials in grades 3-5. The three-step process included:

  1. Understanding the Standards
  2. Investigating the existing instructional materials
  3. Finding and creating improvements in the materials using the worksheets attached

The goal of this work was to create a replicable process for teachers intending to adapt their materials, and to help create an environment of trust, where teachers felt empowered with the knowledge, confidence, and authority to change their own instructional materials in a way that better reflectes the Standards. To learn more about the work of these districts, read the “Collaborative Learning and Updating Materials” article from Aligned or access the complete case study.

  • Making the Shifts

    How does this task exemplify the instructional Shifts required by CCSSM?

    Focus Belongs to the major work of fourth grade
    Coherence Builds on work students did in grade 3 with comparing fractions and equivalence (3.NF.A.3), sets students up for understanding the reasonableness of their answers with fraction operations in grade 5
    Rigor Conceptual Understanding: primary in this task
    Procedural Skill and Fluency: not targeted in this task
    Application:not targeted in this task
