Multiplication and Division
·
Primary
(Outcomes in parenthesis are marginally related to multiplication and division)
NOTE: Within the curriculum outcomes specified, are
a variety of useful approaches to teaching multiplication and division.
KSCO (iii) By
the end of grade 3, students will be expected to create and model problem
situations involving whole
numbers using one or more of the four basic operations.
SCO B1
(count the results when small groups are combined)

small groups are separated)
Grade One:
KSCO (i)
SCO B1: (recognize
that addition is used to represent the joining of two groups.)
Note: it is assumed that in order to learn how to
multiply and divide, students must learn how to add and subtract first.
SCOB2: (recognize
that subtraction is used to represent separating situation.)
KSCO (ii)
SCOB3: (recognize
the relationship between addition and subtraction.)

number patterns to help solve addition and subtraction questions.)
Grade Two:
KSCO (i)
SCOA2: count
in a variety of ways
SCOA5: describe
numbers in a variety of ways
SCOB1:
recognize that multiplication can be used to determine the total amount in
groups of equal size.
SCOB2: recognize
that division can mean determining how many groups of a fixed size are in a
larger groups or fair sharing.
KSCO (ii) and

several meanings for division.
KSCO (ii)
SCOB3: recognize
the relationship between multiplication and division.

principles of multiplication and division.
SCOB8: relate
multiplication and division facts.

to estimate multiplication and division situations.
KSCO (ii)
SCOC3: use
and recognize the patterns in a multiplication table.
KSCO (iii)
SCOC4:
record a repeated addition pattern using multiplicative notation.
SCOC5: recognize
the meaning of open sentences of the forms:
A % B
= /
A % 0 =
C
0 % B
= C

an understanding of multiplication meanings and applications.
SCOB3: demonstrate
an understanding of the various meanings of division.
SCOB4: multiply
2 or 3 digit numbers by single digit numbers concretely, pictorially, and symbolically.
SCOB5: divide
2 or 3 digit whole numbers by a single digit divisor.
KSCO (iv)
SCOB8: relate
multiplication and division facts, using principles of these operations.
SCOB9: demonstrate
a knowledge of multiplication facts to 9%9.
KSCO (vi)
SCOB16:
mentally multiply 2 digit numbers by 10 or 100.
KSCO (i)
SCOC2:
apply the pattern identified when multiplying by increasing powers of ten.
KSCO (ii) and
(iii)
SCOC4: understand
how a change in either a or b in a + b, a – b, a %
b, or a + b
will affect the result of the computation.
SCOC5: represent
multiplication facts in a table or graphically.
SCOC6: complete
open sentences of the forms: A % B
= ,
A % - =
C, A + B
= 0,
and A + 0 =
C

and create multiplication and division problems involving whole numbers and/or
decimals.
KSCO (vi)
SCOB13: perform
appropriate mental multiplication with facility.
SCOB14: divide
numbers mentally when appropriate.
