       TOPIC 7 : LENGTH 

          a.) Conversion between Units of Length

                    1 cm  = 10 mm

                    1 m    = 100 cm

                    1 km  = 1000 m 

        

        TOPIC 8 : MASS
           a.) Conversion between Units of Mass
                   
                   1 kg = 1000 g

        TOPIC 9 ; VOLUME OF LIQUID
           a.) Conversion between Units of Volume of Liquid    
  
                   1 l  = 1000 ml

:        
    TOPIC 10 : SHAPE AND SPACE
           a.) Perimeter 
            
                   Perimeter = Total length of the outer sides of the shape.

            b.) Area 
                  
              -  Area of  a square or rectangle = length x Breadth

                 - Area of a triangle = 1 x Base x Height

                                                   2       

          
           c.) Volume of a cube or cuboid = Length x Breadth x Height


           d.) Two Dimensional Shapes

      TOPIC 11 : DATA HANDLING 
       a.) Average 
           

                     Average =    Total of quantities

                                   Number of quantities
           
            Total of Quantity = Average x Number of quantity
         
            Number of quantity = Total of quantity
                                              Average
     
       b.) Frequency, Mode, Maximum Value, Minimum Value, Range and Mean

•       Frequency = the frequency of an event or value is the number of times it  occur.
•       Mode = the value or item that occurs the most number of times.
•       Maximum value = the highest value in a set of data
•      Minimum value = the lowest value in a set of data
•      Range = maximum value - minimum value
•      Mean  

                   Mean = Total of the values
                               Total number of values
