Fun with geometrical figures
Does your child know the shapes of Geometry? To understand geometry, student must first become familiar with different kinds of shapes. In these second and third- grade geometry worksheets he'll practice finding the Open and closed geometric shapes and solid figures in geometry on a variety of different shapes.
Knowing how to identify geometric figures is important to understanding the basic skills for geometry. Simple shapes can be described by basic geometric objects such as a set of two or more points, a line, a curve, a plane figure, a solid figure.
Geometrical figures
Point: A point, it is represented by a dot(.), it shows a definite position.
Line segment: A line segment has two end points and has a definite length.
AB is a line segment. It is represented as seg AB.
Line: A line has no end points and extends indefinite in both directions. It has no definite length.
Ray: A ray has one end point and extends indefinite in one direction. It has no definite length.
AB is a ray with A as the initial point. It is represented as ray AB.
Types of lines:
There are four types of lines.
1. Slanting line
2. Vertical line
3. Horizontal line
4. Curved line
Many things around us have straight edges. For example, kite, notebook, color box.
Some other things have curved eges. Ex. Wheel, bowl, bangles.
Open and closed figure
Open shapes suggest continuation, while closed shapes denote rigid ness. We can use the curved and straight line to make different shapes.
plane shapes
The plane has two dimensions: length and width. Plane shapes are recognized by its vertices. The point where two lines meet is called the vertex. The plural of vertex is vertices.
All these shapes are called plane shapes.
Rectangle: A rectangle has 4 sides and 4 vertices.
In a rectangle, the opposite sides have same length.
Triangle: A Triangle has 3 sides and 3 vertices.
Square: A Square has 4 sides and 4 vertices.
In a Square, all sides have same length.
Circle and Oval: A rectangle has 0 sides and 0 vertices.
Solid figures: 
Sphere: A sphere is a figure has 1 face, 0 edges and no corners.
Cube: A cube is a three-dimensional shape. It has 6 faces, 12 edges and 8 vertices.
Cylinder :A cylinder has two faces that are circles.
Cone: A cone is a figure has 2 curved face, 1 edge and 1 corner. An ice-cream cone is the example of this shape.
Hands-on activity for teaching shapes
1. There are many hands-on activities that will familiarize children with the different shapes. Tracing the faces of objects is a great activity for teaching shapes. Items such as post card, water bottles, books, and bowls can be traced. First, they trace each side yellow and draw a blue circle on each corner. Then students can identify the shape they traced.
Activity Time:
1. Take a sheet of paper.
2. Make different shapes with it like, rectangle, triangle, circle.
3. Count their corners.
4. Which shapes have no corners?
5. Fold in half every paper of shapes.
a. How many corners do it have now?
b Which new shapes are you finding now?
