Mental
Math Chain 1 (Click to view Video)
Ability to
do mental math is very important in life. This game helps children
to solve simple sums of addition, subtraction, multiplication,
fraction and percentage mentally and form a mental math chain.
Playing this game in the class helps children initiate the habit
of mental math and use this ability to do calculation in their
day-to-day life.
Each
set contains
2 packs of 41 Corrugated rectangular pieces of blue & red
colour , having various simple sums of addition , subtraction,
multiplication, fraction and percentages. The red cards are
"easy" & the blue cards are
"difficult".
Each card is printed back to back, one side is English & the
other side is in Gujarati.
|
| There are 2 games in each
set. There are 41 cards, so 41 students can together play this
game. The educator will decide whether they will play the
"easy" game or the "difficult" game. Eg. of
difficult game is explained below. |
|
Everybody is sitting down,
the student having the "Start" card gets up,
goes to the teacher's table, faces the class, and announces in a
slow, clear, and loud voice: "I have 10, I want 10 more",
and remains standing there.
|
| All the students start
mentally calculating the answer (which is 20) and the student
having 20 on her card gets up, goes to the teacher's table,
faces the class and announces in a slow, clear, and loud voice:
"I have 20, I want 9 less", and remains standing
there. And so on..... |
| Please note that she does
not say the answer, that 20-9=11, nobody should speak out the
answer unless they have the correct card. |
| When the sum is presented
to them for e.g. I have 20, I want 9 less, in the mind of each
student a mental arithmetic process begins. This process should
not be cut short by any student giving the answer unless she has
the card also. The game ends when we have the "Finish"
card and everybody is standing and nobody is sitting. If the
number of students is less than 41,then some of the students can
be given two cards each. |
| Sometimes a particular
student may have difficulty and because of one student the game
may come to a halt. Sharp observation skills of the educator
will come in handy. She might like to go near this particular
student and through whispers help her understand the sum and
arrive at the answer. Care should be taken not to embarrass the
student but to treat such a situation with respect and dignity,
and a part of the learning process. |
| Ability to do mental math
is very important in life. By playing this game in class we are
initiating the habit of mental math. Deliberately simple sums
have been given, being the first in mental math process. It
covers the following 5 operations : |
| Addition |
more |
| Subtraction |
less |
| Multiplication |
times this |
| Fraction |
1/7 of this |
| Percentage |
20% of this |
| Teaching Learning
Materials (TLM) can make learning much more effective and fun in
classrooms. |
| Taleem is an
initiative in this direction. |
