Counting in 100s is great fun because it’s really easy. 

If you look at the number 100 it is made up of 3 numbers or digits: 1, 0, 0

The last two numbers are 0s. 

If you start with the number 100 and keep adding 100, all the numbers will end in two 0s. 

Have a look:

100,   200,   300,   400,   500,   600,   700,   800,   900,   1000

 

See how easy that is? Now it's your turn to start the activities!
