NUMBER RODS

MATERIAL REQUIRED

45 WOODEN PIECES OF SAME SIZE

AND GLUE.

​

CHOOSE SAME SIZE 45 WOODEN PIECES.

 ON ONE WOODEN PIECE MARK AS NUMBER

​

GLUE TWO WOODEN PIECES TOGETHER,

TO MAKE A SMALL ROD AND DRAW

NUMBER 2 ON THE END ON THE ROD.

 

GLUE THREE WOODEN PIECES TOGETHER  

AND MARK NUMBER 3 ON THE END ON THE ROD.

​

REPEAT THE PROCEDURE TO MAKE ROD

WITH 4 PIECES THEN 5 AND  KEEP GOING

TILL YOU GET 9TH ROD WITH NINE WOODEN PIECES.

​

ARRANGE ALL THE RODS FROM SMALLEST TO

BIGGEST. EACH UNIT MAYBE COLOURED RED

AND BLUE ALTERNATELY.

​

PROCEDURE:

Use one wooden piece for rod denoting number one. Glue two wooden pieces together to make the number two rod. This way the rod marked as number two will be double the size of number one rod. Glue three wooden pieces and mark number 3 and so on. Finally glue nine wooden pieces together and mark as number nine. This way all the 45 wooden pieces will be used

 

HOW TO USE NUMBER RODS:

Arrange the rods in order of longest to shortest. Place the longest number rod on top and then place the next longest rod and so on from numbers 9 to 1. They can then take a piece of paper and copy numbers from 1 to 9. Number Rods are the first stage in teaching math to children from numbers 0-9.  With the help of number rods, the children learn the numbers and their sequence and the quantity associated with the number.

​

The authentic Montessori material has a 10 cm x 2.5 size number one rod. The DIY material uses wooden pieces of any size available in Dollar store but keep in mind to use all 45 wooden pieces of the same size so the units progress in equal steps.
