The mysterious disappearance of Inspector Quadro leaves several case files incomplete and unsolved. Students are called upon to gather evidence to unmask the identity and area of the mysterious quadrilaterals.
This versatile activity includes seven 'unsolved case files' that are arranged in progressive order of difficulty and one template for you to add your own. It offers several options for differentiated instruction. It can be used:
*As an individual in-class assessment. Pick and choose the difficulty according to the class or individual students.
*As a take-home project or assessment. Assign all seven cases or allow students to choose. You can assign point values to encourage students to attempt more difficult cases.
*As a group project. Assign all cases to a group of 3 or 4 students. They can decide whether it's best to divide and conquer or collaborate.
This activity is a cumulative assessment for a quadrilaterals unit. Students should already be comfortable with:
*Properties of Special Quadrilaterals (parallelogram, rectangle, square, rhombus, trapezoid, kite)
*Distance and Slope Formulas
*Slope Criteria for Parallel and Perpendicular Lines
Included with this download are student activity pages; answer guide; grading rubric; and cover sheet with essential questions, common core standards alignment, and teacher notes.
