Frequently Asked Questions

What is working backwards in P4 Math?
Working backwards is a problem-solving strategy where you start with the end result and reverse the steps to find the original number or value.
When should my child use working backwards?
Use it when the problem gives you the final answer and a series of actions or changes that led to it. Look for keywords like ended up with, after, or problems describing a sequence of events.
How do you work backwards in a problem sum?
Identify the final result, then reverse each step. If the problem says added 5, you would subtract 5 when working backwards. Do the opposite operation for each step in reverse order.
Can you give an example of a working backwards problem?
A baker sold half his cakes and then sold 10 more. He had 15 cakes left. How many cakes did he start with? (Answer: 60. 15+10=25, 25x2=50)
What are some common mistakes when working backwards?
Forgetting to reverse the order of operations, using the wrong operation (adding instead of subtracting), or misreading the problem. Double-check each step!
How can I help my child practice working backwards?
Start with simple problems and gradually increase the complexity. Encourage them to show their working clearly and check their answers by working forward from their starting number.
Is working backwards useful for PSLE preparation?
Yes, working backwards is a valuable heuristic that can be applied to various problem types in upper primary and is a good tool for PSLE Math.
