NUMBER RODS
ASCENDING ORDER
Asequence of numbers which are not
decreasing but ascend gradually in its own wayis called increasing numbers.
Kids often experience complexity in learning Increasing numbers.
Now, we make it easy by using the Number
Rods.
We always use Red colour cube in Odd
number places and Blue colour cube in Even number paces.
ROD 01:
It is a red cube. It represents 1 unit.
Placing
the Rod 01 in the Number Rod Board is given in Diagram 1.

ROD 02:
After
placing Rod 1 on the Number Rods Board as in Diagram 1, place the Rod 2 in the
next column of the Number Rods Board as in Diagram 2.
It is a cuboid, made
up of two cubes of side 2.5 cms each placed one over the other.
In this rod red unit represents 1 and the blue unit represents 2.
So, while keeping
this rod on the board the red unit
should be placed on the bottom frame which acts as a stand.
It means that the Top of Number rod in
column 2 is bigger than the Rod 1 in Column 1.

ROD 03:
After
placing Rod 2 on the Number Rods Board as in Diagram 2, place the Rod 3 in the
next column of the Number Rods Board as in Diagram 3.
It is a cuboid consisting of one blue
unit fixed with two red units on top and bottom.
There is no problem in placing this rod
on stand, because both the ends are made up of red units.
It means that the Top of Number rod in
column 3 is bigger than the Rod 2 & Rod 1 in Column 2 & Column 1
respectively.
Now the order of numbers is 1, 2, 3.
This order is known as Ascending Order.

ROD 04:
After
placing Rod 3 on the Number Rods Board as in Diagram 3, place the Rod 4 in the
next column of the Number Rods Board as in Diagram 4.
It
consists of 4 units of which 2 are red and 2 are blue. They are alternatively
placed one over the other. The red end of this rod is to be placed on the stand
during operation.
It means that the Top of Number rod in
column 4 is bigger than the other Rods in Previous Columns.
Now the order of numbers is 1, 2, 3, 4.
This order is known as Ascending Order.
