Achievement Indicators:
Add the digits from each column to determine the 
final answer.
This continues until all triangles are filled.
5N5.2(Continued) Describe 
a solution procedure for 
determining the product of two 
given two-digit factors, using a 
pictorial representation such as an 
area model.
5N5.3 (Continued) Solve a 
given multiplication problem in 
context, using personal strategies, 
and record the process.
5N5.4 Illustrate partial products 
in expanded notation for both 
factors.
5N5.5 Represent both two-digit 
factors in expanded notation to 
illustrate the distributive property.

Resources/Notes
MULTIPLICATION
General Outcome: Develop Number Sense
Authorized Resource
Paper and Pencil
• Ask students to make their own tilted square and use it to multiply 
26 x 43.
(5N5.2, 5N5.3)
• Ask students to use the tilted square to multiply 23 x 45.
(5N5.2)
Performance
• Ask students to use a model to show the amount of money collected 
for school photos if 43 students each bring in $23.00.
(5N5.3) 
• On chart paper with a prepared series of two-digit by two-digit 
multiplication equations, ask students to fill in missing numbers and 
provide justification for their choices.
Example: 45 ×36 
= (40 + 5) × ( __ + 6)
= 40 × 30 + 40 × __ + 5 × __ + 5 × 6
= 1200 + ___ + 150 + 30 = ____
(5N5.4, 5N5.5)
• Noah planted 15 rows of tulips with 24 tulips in each row. When 
determining how many tulips he planted, he wrote the following. 
15
x 24
20
40
10
+200
270
(5N5.4) 
• The fish processing plant finished packaging 25 crates of halibut. 
There were 72 kg of halibut in each crate. Ask students how many 
kilograms of halibut were packaged altogether. They should use 
words, numbers and pictures to solve the problem.
(5N5.3)
Ask students if Noah’s answer is 
correct. They should explain thier 
answer.
