The Long Rods also known as the Red Rods, help the Child to recognize differences in size in one dimension – length.
"..the child must place the rods in the proper sequence from the shortest, which is 10 centimeters in length, to the longest, which is 1 meter in length." A Parents' Guide to the Montessori Classroom by Aline D. Wolf.
The Child learns to distinguish the difference in length with increases of 10cm equal incremental lengths.
