3. Reverse the Operations:

This is the heart of the 'Working Backwards' method. For each step in the problem, perform the inverse operation. If the problem says "add 5," you subtract 5. If it says "multiply by 2," you divide by 2. Be careful to do this in the correct order, reversing the order in which the operations were originally performed.

4. Work Step-by-Step:

Take it one step at a time. Don't try to do everything at once. This helps prevent errors and keeps things manageable, especially for younger learners. Show your workings clearly, so your child can see the logic behind each step.

5. Check Your Answer:

Once you've found a potential solution, plug it back into the original problem to see if it works. This is a crucial step to ensure accuracy and build confidence. If the answer doesn't match, go back and review your steps to identify any errors.

Example:

"Sarah had some stickers. She gave 12 stickers to her friend and then bought 25 more. Now she has 43 stickers. How many stickers did Sarah have at first?"

* **Final Result:** 43 stickers * **Reverse Steps:** * Before buying 25 stickers, she had 43 - 25 = 18 stickers. * Before giving away 12 stickers, she had 18 + 12 = 30 stickers.

Therefore, Sarah had 30 stickers at first.

Fun Fact: The 'Working Backwards' heuristic isn't just for math! It's used in computer science for debugging code and even in detective work to solve crimes!

Problem-Solving Strategies: Heuristics

Heuristics are mental shortcuts or strategies that help us solve problems more efficiently. They're like having a toolbox full of different tools, each suited for a specific type of problem. The 'Working Backwards' method is just one of many useful heuristics. Mastering these strategies is key to how to excel in Singapore Primary 3 math and beyond.

Common Heuristics for Primary 3 Math

Here are a few other heuristics that are commonly taught in Singapore Primary schools:

  • **Model Drawing (Bar Model):** Visual representation of the problem using bars to represent quantities.
  • **Guess and Check:** Making an educated guess and then adjusting it based on the results.
  • **Looking for a Pattern:** Identifying patterns in numbers or shapes to solve problems.
  • **Making a List:** Systematically listing possibilities to find a solution.

Interesting Fact: Singapore's emphasis on heuristics in math education is one of the reasons why Singaporean students consistently perform well in international math competitions!

History: The use of heuristics in problem-solving dates back to ancient Greece, with mathematicians like Archimedes using intuitive methods to solve complex problems.
