**Multiples of 100**

Numbers that are multiples of 100 will always end in at least 2 zeros.

100 200 300 400 500 600 700 800 900 1,000 1,100

All of these numbers are multiples of 100

We can see that the number 1,000 has 3 zeros.

1,000 is a multiple of 100 but it is also a multiple of 1,000 ( 10 x 100 and 1 x 1,000 )

150 210 320 301 30 450 660

We can see that none of the numbers above end in 2 zeros, so they are not multiples of 100.

**Multiples of 50**

Numbers that are multiples of 50 will always end in either 50 or 00

50 100 150 200 250 300 350 400 450 500 ... 1,000 1,050

All of these numbers are multiples of 50

We can see that the number 1,000 has 3 zeros.

1,000 is a multiple of 50 but it is also a multiple of 100 and 1,000 ( 20 x 50, 10 x 100 and 1 x 1,000 )

170 201 305 455 504 551

We can see that none of the numbers above end in 50 or 2 zeros, so they are not multiples of 50

Why don't you have a go counting in multiples of 50 and 100 - good luck!
