Interview
• Present the following problem to students: Jennifer has 18 pieces of 
string and each piece is 32 cm in length. Estimate the total length of 
string. 
Use the following prompts to guide the student’s thinking, if
necessary: 
• State the problem in your own words. 
• What do each of the numbers in the problem represent? 
• What is the unknown in the problem? 
• What number sentence could you write to show the meaning of 
the problem? 
• What operation will you use to solve the problem? Explain. 
Use an estimation strategy that makes sense to you to find the answer 
to the problem. Explain your thinking as you write the numbers. 
(Hint: provide guidance in using the front-end or compatible 
numbers strategies, if necessary.) 
Explain how you know your estimate is quite close to the calculated 
answer. (Hint: have the student use compensation, if appropriate, to 
refine the estimate.) 
Calculate the answer to the problem using paper and pencil to record 
your personal strategy. 
Compare your calculated answer with your estimated answer. 
Another prompt for this process may be: There are 52 candies in
each of 23 bags. Estimate how many candies there are in total. 
(5N2.6)
• Ask students to create a problem that requires only an estimated 
answer to solve it. They could then solve the created problem by 
estimating the answer and explaining their thinking.
