This material can be used
to demonstrate the concept of the place value of a number. A
single student can use this material. This material helps
children to visualise the place value of a number. The size of
the card increases as the place value increases. |

Step
1: The student takes a fresh sheet of paper, draws a
margin, writes her name and date on the top right hand corner
and the name of the exercise in the center of the page. |

Step
2: Then she writes a four digit number in the paper, say
9876. |

Step
3: She then checks the left most digit in the number. The
left most digit in the given example being 9, she checks for the
card whose left most digit is 9 and the number of digits in the
card are 4. She finds that the card is 9000. She then places the
card on the table. |

Step
4: She then checks the second digit from left in the
number. The second digit being 8, she again checks for the card
whose left most digit is 8 and the number of digits in the card
are 3. She finds that the card is 800. She then places this card
on top of the earlier card, taking care that the digit 9 is
visible. |

Step
5: She then checks the third digit from left in the
number. The third digit being 7, she again checks for the card
whose left most digit is 7 and the number of digits in the card
are 2. She finds that the card is 70. She then places this card
on top of the earlier two cards, taking care that the digit 9
and 8 are visible. |

Step
6: She then checks the fourth digit from left in the
number. The fourth digit being 6. She again checks for the card
whose left most digit is 6 and the number of digits in the card
is 1. She finds that the card is 6. She then places this card on
top of the earlier three cards, taking care that the digit 9, 8
and 7 are visible. |

Step
7: She now realises that 9876 is actually 9000 + 800 + 70
+ 6 and as you move from left to right the place value of the
number changes. In this case it is 1000, 100, 10 and 1and the
face value of the number is 9876. |
