Numbers Showing on Spike Abacus

Numbers showing on spike abacus helps the students to understand the number and its place value. Spike abacus is very helpful to understand the concept of magnitude and name of a number. We know that the spike-abacus represents the number of multi-digits where the digits are represented by the spikes of the abacus.


The spikes from right to left represent the places of the place values of the digits in increasing order i.e., 1, 10, 100, ………. etc.

O (unit or ones) ----- In ones or unit place we see 3 beads. 

T (tens) ----- In tens place we see 4 beads. 

(hundreds) ----- In hundreds place we see 6 beads.

Th (thousands) ----- In thousands place we see 1 bead. 

T th (ten thousands) ----- In ten thousands place we see 5 beads. 

Under this topic we will mainly learn about showing the 1 digit number on spike abacus, 2 digits number on spike abacus, 3 digits number on spike abacus, 4 digits number on spike abacus, 5 digits number on spike abacus and so on….


Representation of Numbers on the Abacus:

We can show 1000 on an abacus with four vertical rods. The rods represent place value of thousands, hundreds, tens and ones. We add beads on the rods to show different numbers. Each rod can hold up to 9 beads.

Number 99 on the Abacus
Number 100 on the Abacus

This shows 9 tens and 9 ones. The number is 99.



If we add 1 more to 99 it is 10 tens. Regroup 10 tens as 1 hundred.



Number 999 on the Abacus
Number 1000 on the Abacus

This shows 9 hundreds, 9 tens and 9 ones. The number is 999.

If we add 1 more to 999 it is 10 hundreds. Regroup 10 hundreds as 1 thousand. 1 bead in the thousands place represents 1 thousand.

1 bead in the thousands place represents 1 thousand.
