MATHEMATICS 5 CURRICULUM GUIDE 2015
Specific Outcomes
DIVISION 
Suggestions for Teaching and Learning
Students will be expected to:
Number
5N6.1 (Continued) Students 
investigate a variety of strategies 
and become proficient in at least 
one appropriate and efficient 
division strategy that they 
understand.
5N6 Continued...
5N6.4 Solve a given division 
problem in context, using personal 
strategies, and record the process.
Trial-and-error, or guess-and-check, is sometimes an appropriate 
strategy for solving division problems which are open-ended such as:
Stephen shared $24.00 evenly among his friends. Each received the
same amount in dollars. How many friends did Stephen have? 
Students should be able to use their knowledge of division facts and 
estimation to guess and check possible solutions to this problem. They 
should share their solutions with the class. Through this sharing, they 
should recognize that there is more than one solution to the problem.
Base ten blocks are also useful tools for developing understanding 
of the standard algorithm for division. Students should divide
three-digit numbers by one-digit numbers using base ten blocks, 
recording their calculations symbolically. Through discussion, 
students should be able to access their prior knowledge of base ten and 
subtraction to complete this method and make connections between 
the base ten models and the standard algorithm. Remind students to 
estimate before they divide, and use this estimate to determine if their 
answer is reasonable.
Students may select one of many methods to find solutions with 
division. They should be asked to describe their process. When the 
method being used is not efficient, the student should be led to try 
another.
Ask students to discuss how they would solve problems such as:
• 
160 treats were sorted into loot bags for Bob’s birthday party so 
that all bags had the same amount. There were fewer than 25 
children invited to the party. How many people could have been 
invited?
• 
At Salmonier Nature Park, there are 57 animals in seven groups that 
are mostly equal. How many animals are in most groups?
Ask students to record and explain their strategies.
