1. Similar Shape
Unit Overview
In this unit, students will develop sense of shapes and will develop basic
mathematical thinking skills by observing various shapes. The accurate
observation and analysis of shapes is the basis of the study of shapes. Initially,
students identify shapes through overall recognition rather than a detailed
study of the shape characteristics. It is important for students to compare the
characteristics of different shapes and identify their differences.
