Solving Geometry Problems: Floodlights

View Resource

Description

Overview:
This lesson unit is intended to help teachers assess how well students are able to identify and use geometrical knowledge to solve a problem. In particular, this unit aims to identify and help students who have difficulty in: making a mathematical model of a geometrical situation; drawing diagrams to help with solving a problem; identifying similar triangles and using their properties to solve problems; and tracking and reviewing strategic decisions when problem-solving.

Lesson unit serves as a formative assessment tool in which students identify and use geometric knowledge to solve problems. Students are required to make mathematical models to solve geometric situations, draw diagrams to solve problems, identify similar triangles and use their properties to solve problems, and make strategic decisions when problem-solving.

Students work individually and in small cooperative learning groups to build conceptual understanding through the use of a range of mathematical practices.

Students analyze sample solutions to build their conceptual understanding and to provide feedback to (sample) peers.

Materials provide instructional strategies to address common misconceptions.
