5.NBT.6. Fluently divide up to 4-digit dividends and
2-digit divisors by using at least one of the
following methods: strategies based on place value,
the properties of operations, and/or the
relationship between multiplication and division.
Illustrate and explain the calculation by using
equations or concrete models. (e.g., rectangular
arrays, area models).
VOCABULARY
Division, in math, is the process of splitting a number
into multiple parts. Division can be represented as seen
below OR by / and ÷.
Remainder, in math, is the number that is left over;
the number is left over because there is not enough
to put it into an equal group.
“I Do”/Application 11-2-2015
At the Highland Falls pumpkin-growing
contest, the prize winning pumpkin contains
360 seeds. The proud farmer plans to sell his
seeds in packs of 12. How many packs can he
make using all the seeds?

1 zero in the quotient
Step 1: Find and
solve the basic
math fact.
Step 2: Count the zeros outside
of the boxes in the dividend and
divisor, then subtract.
Step 4: The difference tells
you how many zeros to place
in your quotient
1,200 ÷ 3 = 4 00
450,000 ÷ 90 = 5,000
15,000 ÷ 5,000 = 3
56,000 ÷ 80 = 7 00
4,200,000 ÷ 7,000 = 600

Step 1:
Round your dividend and divisor
to the nearest place value
(hundred and ten in this case)
Step 2: Use basic
facts to divide your
digits (excluding
zeros)
4 0 = 20
Step 3: Use the strategy learned
earlier to find your quotient
estimate
1,859 ÷ 481 =
2,0 00 ÷ 5 00 = 4
Step 1:
Look at the first couple of
numbers of the dividend and
the first number of the divisor.
Step 2:
Find
the closest basic
division fact to these
numbers
Step 3:
Use the
basic fact to change the dividend
and divisor to compatible
numbers, and divide.
