**PATTERNS**in multiplication (skip-counting/repeated addition) generate

**RULES**that can be used to

**other (larger) numbers.**

__analyze__When counting by

**2**s, all multiples have a

**2, 4, 6, 8, or 0**in the ONES place.

When analyzing large, multi-digit numbers, the digit in the

**ONES**place tells us it's

**EVEN**and therefore, divisible by

**2**.

When counting by

**5**s, all multiples have a

**5, or 0**in the ONES place.

When analyzing large, multi-digit numbers, the digit in the

**ONES**place tells us it's divisible by

**5**.

When counting by

**10**s, all multiples have a

**0**in the ONES place.

When analyzing large, multi-digit numbers, the digit in the

**ONES**place tells us it's divisible by

**10**.
