This document contains a lesson plan for a Grade 2 geometry class on flat shapes. The plan includes introducing new vocabulary about polygon parts, having students cut out shapes and order them by size and number of corners, and doing an artwork activity where they create pictures using the shapes. The teacher found the lesson went well overall but some activities took longer than expected due to having only one hour, and students preferred to work individually rather than in pairs. Audio, video, and picture files are included to support the different activities.
