KAVERI RAMACHANDRAN MATHEMATICS FUN WITH SHAPES CLASS 1 & ABOVE PRIMARY
A shape is the outer form of an object or figure such as circle, rectangle, square, triangle,pentagon etc. There are all kinds of shapes all around us – in the sky, in the sea, on the ground, and in our homes Knowledge about shapes is important to design and provides structure for creative thinking .

LEARNING OBJECTIVES <ul><ul><ul><ul><ul><li>The children will recognize the shapes circle, square, rectangle, and triangle by sight. </li></ul></ul></ul></ul></ul>The children will practice drawing circles, squares, rectangles, and triangles. Children will start drawing objects of different shapes,draw patterns,create more and more rangoli designs and geometrical designs. Children will correlate the objects in the environment with the shapes they have learnt. Children will recognize different shapes in nature like leaves,flowers,fruits etc. The rangoli,kolam and mehendi designs provide excellent practise of geometrical concepts like dots,line segments,curves,and different shapes. All these will increase children’s interest towards Mathematics. Children realize that shapes make life brighter.
