Downtown Redevelopment Proposal – 4th Grade Geometry Performance Task (4.G.A.1–4.G.A.3)

Engage students in meaningful geometry through a real-world urban planning project. In this standards-aligned performance task, students design a downtown map on a 20×20 grid while applying parallel and perpendicular lines, angle classification, quadrilateral hierarchy, and lines of symmetry.

Students take on the role of urban planners and must follow zoning laws that require specific geometric constructions, shape classifications, alignment constraints, and a symmetrical civic plaza. The project emphasizes reasoning, justification, and structured mathematical communication—not just drawing shapes.

Standards Covered

• 4.G.A.1 – Draw and identify parallel and perpendicular lines; classify angles
• 4.G.A.2 – Classify two-dimensional figures based on properties
• 4.G.A.3 – Identify and draw lines of symmetry

What’s Included

• Student Project Packet, 6 pages (print-ready)
• Teacher Guide/Answer Key with discussion prompts and sample responses
• Standards-aligned Scoring Rubric
• Extension ideas for early finishers

Skills Developed

• Geometric construction and labeling
• Quadrilateral classification and hierarchy
• Parallel and perpendicular reasoning
• Symmetry analysis
• Written mathematical explanation

This 2–3 day project works well as a geometry unit performance task, assessment, or culminating activity. It promotes depth of understanding and structured reasoning while keeping students engaged in a purposeful design challenge.
