What are we going to do today?
Today we will solve problems involving
division of multi-digit numbers by one-digit
numbers.
What is division?
Division means to break a number of items into groups that
have the same amount.

Why do you think this is so important
to know?
 We need to know how to divide multi-digits numbers for
upper grades
 It will be on the quarter math test
 It will be on the CST’s
 You will need to know this math skill when you are adults
Let’s do it again!
Step 1: Divide outside
number into first number of
dividend. If the number
inside isn’t big enough then
use the first two numbers

Let’s do it again!
Step 1: Multiply the
dividend with the number
you put in the answer and
place the number under the
2 in the dividend
