  Code : TLM-M-002
Age : 9 - 11 yrs.
  Name: Mental Math Chain - 1
 

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.

How to use
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.
Development aspects
 
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.
