SCO B4: Students will be expected
to divide 2, 3 – and 4 – numbers by
single-digit divisors and investigate
division by 2 – digit divisors.
Student Activities: An Introduction
Give a situation when you use division.
This is your VISION OF DIVISION.
Did you know that there are 6 visions of
division?
Examine the problems on each of the pages
to follow and figure out what vision of
division is being used.
The Visions of Division
Examine the story problems presented by
the teacher to try to discover the Visions of
Division.
The Visions of Division

Identify the Vision of Division for the Word Problems
presented by the teacher
WORD PROBLEM
The
area of a plot of land is 453 square
metres. If the plot is 3 metres long, ABOUT
how wide is the plot?
Now calculate the exact width of the plot.
Use Base-10 materials to find the answer.
What VISION OF DIVISION is used in this
problem?
WORD PROBLEM:
The Key Questions
HOW MANY ARE
IN EACH GROUP?
HOW MANY ARE USED UP?
HOW MANY ARE LEFT?
WORD PROBLEM
There
are 356 bags of healthy snacks placed
into four large cartons. ABOUT how many
bags would be in each box?
How many bags would be in each box? Use
Base-10 materials to find the answer.

There
are 568 tulip bulbs. They are
packaged in sets of 5. ABOUT how many
packages could be made from the bulbs you
have?
How many packages could be made? Use

Find the other factor: 349 ÷ 5
4 281 items with 4 in each group. How
many groups?
WORD PROBLEM
869
items are placed in 20 boxes. How
many items would be placed in each box?
Use an estimation strategy to get your
answer?
How can what you just did help if there are
21 boxes instead of 20 boxes?
Find an estimate of 2713 ÷ 31.

The estimated quotient of 624 and 22
An estimated quotient for 9 118 ÷ 16
653 items with 30 in each group. How many
groups?
Student Activities
B4.1
Use Base-10 blocks to model how to divide
489 by 7.
Practise: Use Base-10 blocks to model how
to divide 869 by 4.
Roll a die three times in order to build a 3digit number. Now roll a fourth time to get
the divisor. Find the quotient.
Student Activities
B4.2
Fill in the boxes in the template below so
that:
– No digit is used more than once
– There is no remainder
– The resulting division sentence is correct
Student Activities
B4.3

Student Activities
B4.4
What division problem is being modeled in
the picture shown to you by the teacher?
Create a word problem that would be solved
by this model.
Practise with more models.
Student Activities
B4.5
612 students in a school are being bussed to
a museum. The law states that a maximum
of 45 students is allowed on each bus.
Estimate how many buses will be needed.
Now calculate how many buses will be
needed.
Student Activities
B4.6
Look at the sample word problems below. Talk about
the remainder? Can it be ignored? Is part of the answer?
Or is rounded up?
– A person has 78 cents. Pens cost 19 cents each. How many
pens can the person buy?
– 126 people need to be transported. Twelve passengers can
travel in each van. How many vans are needed?
– 75 metres of ribbon are to be shared among 10 students to
make crafts. How much ribbon will each student get?
What Vision of Division is used in each question?
Student Activities
B4.6 Continued
Create word problems involving division by
a 2-digit number for each of the following
situations:
– The remainder is ignored
– The remainder is rounded up
– The remainder is part of the answer
“Wow, I just learned the most exciting things about the
division. I can hardly wait to call all of my friends!”
