Fraction Circle 1 (Click to view Video)
This game helps children to
understand that the whole number is made up of fractions. They use
the cards of halves, thirds, quarters, sixths etc.to make a whole
number.
Eg.
2 halves make one whole
3 times one third make one whole
It
helps children to compare the size of the fraction card and
understand its value.
Eg.
By stacking the fractional piece, children clearly see and
understand;
One third is a larger fraction than one quarter but smaller than
one half.
This
game helps children to understand the addition and subtraction of
fractions.
Each
set contains
 4
corrugated circles
 2
sets of ‘halves’ (1/2)
 2
sets of ‘onethird’ (1/3)
 2
sets of ‘quarters’ (1/4)
 2
sets of ‘onesixths’ (1/6)
 2
sets of ‘oneeights’ (1/8)
 2
sets of ‘oneninths’ (1/9)
 Two
dice. One dice with factors 1/2, 1/2., 1/3, 1/4, 1/4 printed
on the six different faces. Another dice with the factors 1/6,
1/6, 1/8, 1/8 and 1/9, 1/9 printed on the six different faces.
The game introduces, in a
fun way, the concept of integration parts into wholes. Before
actually playing the game, we highly recommend giving the child
the opportunity to make herself familiar with the fraction pieces:
their shapes, size and the relation between the different pieces.
Let the child experiment
with the fraction pieces and the rings and make up wholes in as
many different ways as possible.
How
to use
Game
1: (Use only large fraction: 1/2, 1/3, 1/4 and
corresponding dice).
Each player takes one
corrugated circle. The first player rolls the dice, selects the
corresponding fraction piece and places it on the circle. Play
continues clockwise with each player rolling the dice and placing
the corresponding fraction piece on their circle. If the dice
shows a fraction piece that the player cannot or does not want to
use, the turn passes on to the next player. When a circle is
completed the piece are put a side and the piece cannot be use
again. The game continues until all the fraction parts are used.
The winner is the player with the next most complete circle is the
winner. To determine who has the most completed circle place one
set on the top of the other.
Game
2:
(Use the small fractions: 1/6, 1/8, 1/9 and corresponding
dice).
Game rules are same as
version 1.
Game
3: (Use all fraction parts and both the dice).
Player throw both the dice
and select fractional piece. E.g. If 1/2 and 1/6 are rolled, the
player can select 1/2 and 1/6 or 1/3 and 2/6, or 1/6 or any other
combination totaling the SUM of the fractions shown on the dice.
Play continues as in a version 1.
Game
4: (Negative Fractions).
Only one dice is used. The
players discard the fraction piece from their circle according to
the roll of the dice. Fraction pieces remaining can be exchanged
for other corresponding pieces totaling the same fractional value.
E.g. Consider a situation when the dice shows 1/4, the player may
now exchange 1/2 from one of his circle for 2/4 from the remaining
pieces and discard one of these 1/2’s in a accordance with the
roll of the dice. The winner is the first player to discard all
the fractions from both the circles.
There is no concept of time
limit for this game as the purpose is to include the student into
a mood of reflective thinking. At the end of the game children
themselves start realizing the concepts of addition and
subtraction of fractions. The educator might carefully direct a
child to make an intelligent choice in case the child is unable to
figure it out by herself.
Development
aspects
Any rational number can be
represented in the form of a fraction. A fraction is generally
represented as a/b, where a and b are integers and b>0 E.g. 1/2,
1/3, 1/4, 1/6, 2/5, 3/2 etc.
Principle:
 Children
are introduced to the concept of addition and subtraction of
fractions.
 It
is done by associating different pieces with the respective
parts and adding them up to form a complete circle.
 A
complete circle can be formed by combing 1/2, 1/3 and 1/6 or
any other such combination . By discarding 1/9 from 1/3(i.e.
subtracting the smaller fraction 1/9 from the bigger 1/3), two
1/9’s are left.
 It
is important that children link the parts with their
appropriate value.
Teaching Learning Materials (TLM)
can make learning much more effective and fun in classrooms.
Taleem is an initiative in this direction.
