Shapes

Let us learn 2-D and 3-D Shapes

Learning of Space

A polygon, a name derived from Greek meaning many-angled, is a plane geometric figure bounded by three or more sides. Common examples of polygons are triangle, quadrilateral, pentagon and hexagon. All polygons have vertices, which are the angle points where two sides meet. Thus, the number of sides indicates the same number of vertices of a polygon. For example, a four-sided quadrilateral would have four vertices. Similarly, a n-sided polygon would have n vertices.  

Two-dimensional figure is enclosed by straight lines or curves. Various types geometrical shape such as square, rectangle, equilateral triangle, and circle. A triangle has three sides. A quadrilateral has four sides. Figures with round shapes are called circles, and have curved side. A square has four sides equal in length.

Three-dimensional geometric figures such as cube, cuboids, pyramid, sphere, cylinder and cone. Four sides of a cube are equal. Length, width and height of cuboids are different. Cone has a base of a circle. Pyramid has a square base. Pyramid with base of a rectangle. Cylinder has a circled base. Sphere with shape of a ball.

Two Dimensional Geometric Forms

These geometric figures have only two dimensional plane surfaces – length and breadth. A plane surface means that the line joining any two points in the plane lies wholly in the plane.

Measurement of Length, Weight & Volume of Liquid

Conversion of volume of liquid involving litres and millilitres

1000 ml = 1 litre

2 litres = 2 x 1 litre

            = 2 x 1000 ml

            = 2000 ml

2340 ml = 2340 ÷ 1000 l

                 = 2.340 l

Reading scale of Cylinder

Volume of Liquid

Let’s do it together

Volume of Liquid

Come and have a try

To ascertain and read the standard unit of millilitre and write its symbol ml

(1)               The amount of water in the bigger cylinder is 10 times as in the smaller cylinder.

(2)               The smaller cylinder can fill with liquid up to 1000 millilitres.

(3)               Millilitres is a smaller unit for measurement of the amount of liquid.

(4)               The symbol for milliliters is ml

(5)               1 l is equal to 1000 ml

Measure Match (kg)

Have fun with Measurement of Weight

Measurement of Weight

Come and try it

kg to kg and g to g

1 kg = 1000 g

To change kg to g, multiply 1000

3.46 kg to g

3.46 kg = 3.46 x 1000 g = 3460 g

To change g to kg, divide 1000

2768 g to kg and g

2768 g = 2000 g + 768 g

                        = 2000 g ÷ 1000 kg + 768 g

                        = 2 kg 768 g

Changes units of cm and mm

6 cm = 6 x 10 mm = 60 mm

5.4 cm = 5.4 x 10mm = 54 mm

In order to change the unit of cm to mm, we need to multiply the number of cm by 10.

87 mm = 87 ÷ 10 cm = 8.7 cm

24 mm = 24 ÷ 10 cm = 2.4 cm

In order to change the unit of mm to cm, we need to divide the number of mm by 10.

Measurement of length using millimetre (mm) and centimetre (cm)

cm = centimeter

mm = millimeter

1 cm = 10 mm

Come and have fun with Time

Measurement of Time

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours

Read the time

(1)   The minute hand points at 6. The hour hand is between 7 and 8. It is 7.30 (seven thirty).

(2)   The minute hand points at 12. The hour hand points at 8. It is 8 o’clock.

Time

Time Reading from 12-hour Clock

The clock has two moving hands. The longer one is called the minute hand, and the shorter one is called the hour hand. There are 12 numbers, 1 to 12, on the face of the clock. The minute hand takes 5 minutes to move from one number to the next.
