Introduction to Geometry
We live in a three-dimensional world, a reality that can be best understood through geometry. Geometry unlike what is often thought is not just about theorems and proofs. It is also about understanding the relationship between shapes, recognising patterns, making connections and logical decisions. Geometry is about developing spatial ability. Children from an early age observe different shapes without knowing their names. Knowledge of three-dimensional structures helps solidify their knowledge of two-dimensional structures.
The Big Idea
The topics under Geometry like shapes are introduced early on, at age 5 or 6, starting with basic two-dimensional shapes like squares, triangles and circles. Eventually moving to more applicable topics like finding out area, perimeter of shapes and plots, understanding different angles, understanding 3D solids, calculating the surface area and volume of different containers, etc.
How do I understand?
At Cuemath the concept of shapes is introduced as early as KG. The kid learns about different shapes, their names. By Grade 2 the children are exposed to the relationship between the 3D and the 2D shapes. Moving up in the grade we cover different sub-topics like names and properties of angles, area and perimeter of shapes, calculating the volume and surface area of different 3D shapes.
These topics are best introduced with some math manipulatives like models of solid shapes, paper nets to understand the concept of volume and surface area better. Geoboards are used to help children build and explore shapes. Using manipulatives strengthens the child’s understanding of these concepts.
