        Afroz  was  making  a  drawing.  When  he  coloured                   part,  the  electricity  went
                                                                           7


        off.  His  mother  gave  a  candle  that  was  already  burnt  about  one-fourth.  He
        lighted  the  candle  and  coloured  the  remaining  part  of  the  drawing.  When  he
        completed his drawing, the candle was left one-fourth only.


             (a)  What part of the drawing was coloured after lighting the candle?

             (b)  What part of the candle was given to Afroz?

             (c)  What  part  of  the  candle  burnt  when  Afroz  coloured  the  remaining
                   portion?

        Aim: To  reinforce  the  concept  of addition  and  subtraction  of fractions  with
        same denominator on the number line


        Materials: Fraction slips, paper and pencil

        Instruction for teachers:

        Divide the class into the groups of 4–5 students. Make 20 slips of fractions for
        each group. Write one fraction on one side of the slip and another fraction with

        the same denominator on the other side. Other fraction may have the same or
        different  colour.  If  fractions  written  on  the  slip  are  of  the  same  colour,  they


        will be added and if they are of different colours, they will be subtracted.

        Method:  First, take two fractions and illustrate how to add and subtract using the
                                                                                            5         2
        number line on the blackboard. For example, consider the fractions                      and     .

        Step 1:  Draw  a  number  line  and  mark  two  points  0 and  1.  Then,  divide the
                    length between 0 and 1 into 8 equal parts.
