NS 8 I can explain multiplication using repeated addition, skip
counting arrays and area model. For example:
ü I can write an equation for word problems with
NS 9 I can explain division by using repeated subtraction,
arrays, sharing equally, and area model. For example:
ü I can write a story problem for division.
ü I can identify what a remainder means in a division
NS 10 I can explain and use relationships between operations,

ü Understand multiplication and division as opposite operations;
ü Understand that multiplication is repeated addition;
ü Understand that division is repeated subtraction.
NS 11 I can show and use the commutative property (order)
for addition (2+3=3+2) and multiplication (2x3=3x2)
and the associative property (grouping) for addition
(2+4)+3=2+(4+3) and multiplication (2x4)x3=2x(4x3).
NS 13 I can show I know my multiplication facts through 10
and division facts to 10.
NS 14 I can multiply 2- and 3- digit numbers by a single-digit
number (without remainders for division). I can divide 2-
and 3-digit numbers by a single-digit number.
P 1 I can describe the multiplication pattern or state the rule
