Suppose you want to save for a new bicycle. You need information before you set a savings goal. How much does a suitable bicycle cost? Where can you check the price? A friend’s guess may help you start, but it may not be enough to make a decision. In this lesson, you will learn how to identify sources that are relevant, clear, and trustworthy. A source is a person, organization, or place that provides information. A financial goal is something you want to do with money, such as save for an item or plan how to use your money.

What you will learn

Explain what makes a source useful and reliable for a financial goal.
Compare information from different sources before relying on it.
Choose suitable sources for a goal and explain why they fit.

Begin with the goal and the question

A financial goal helps you decide what information to look for. Start by stating the goal in a clear way. For example: “I want to save for a bicycle.” Then ask a question that the information can answer, such as “What is the price of a bicycle that meets my needs?”

A source is relevant when its information connects to your question. A store’s current listing for a bicycle may help you learn its listed price. A page about bicycle history would not answer that price question, even if it is accurate.

Before trusting a source, check who made it and what information it gives. An organization is a group, such as a government office, bank, or store. A source may be more useful when it clearly names the organization or person responsible and explains the information. These checks do not prove that every detail is correct. They help you decide whether to use the source and whether to check another one.

State the financial goal first.
Ask a question that fits the goal.
Choose information that answers that question.
Notice who provided the information.

Check whether the information is dependable

Reliable information is information you have good reason to trust for the question you are asking. A source is not reliable just because it looks official or has a confident tone. Look for signs that help you judge it.

Check whether the source names who provided the information. Look for details that make the information understandable, such as what price refers to and when it was listed. A date matters because prices and other financial details can change. If the date is missing, you may not know whether the information is still useful.

Consider the source’s purpose. Purpose means the reason the source was made. A store may share prices to help customers choose products and to sell items. That does not automatically make its price information unreliable, but you should notice that the store is trying to sell something. A source that explains its information clearly can be easier to assess than one that gives a claim without saying where it came from.

Compare the information with another suitable source when you can. If two sources give different prices, do not quietly pick the one you prefer. Check that both refer to the same kind of item and that the information is current. You may need to ask a trusted adult or contact the source to clarify. Do not treat a comparison as proof if the sources are unclear or out of date.

Check who provided the information, what it says, and when it applies.
Notice the source’s purpose.
Compare suitable sources when possible.
If details conflict or are unclear, pause and check further.

Match the source to the goal

Different goals call for different information. If your goal is to save for a particular item, a current price from the seller may help with that goal. If your goal involves understanding a bank account, information from the bank about that account may be relevant. In either case, read what the information actually covers; do not assume it answers questions it does not discuss.

A helpful way to organize your thinking is to compare sources using the same questions. The small table below uses hypothetical examples. It does not report real prices or offers. “Hypothetical” means made up for practice.

Suppose a learner wants to save for a bicycle. One source is a store listing that names a bicycle and shows a price and date. Another is an undated post that says, “Bikes are cheap here,” without saying who wrote it. The store listing is more useful for checking that bicycle’s listed price because it gives specific information and a date. The post may suggest something to investigate, but it does not provide enough detail to rely on for a goal.

A source can be reliable for one question but not another. A bicycle listing may help with the listed price, but it may not tell you whether the bicycle suits you. Keep your question in view, and do not stretch a source beyond the information it gives.

Use a source that fits the exact question.
Specific, dated information is easier to check than a vague claim.
A source may answer one question but not another.

Make and explain your choice

When you choose a source, give a reason. Instead of saying “This one looks trustworthy,” explain what you checked: who provided it, whether it answers your question, whether its information is clear and dated, and whether another source supports it.

You do not need to accept or reject information based on only one clue. Use the clues together. If you cannot tell who made a source, what it means, or when it applies, say that you are unsure. Finding reliable information includes knowing when you need to check more.

For practice, imagine your goal is to find out the listed cost of a particular school bag. A dated store listing that names the bag may be a useful source. A friend’s memory of a price from last year may be less useful for the current listed cost. You could check another suitable listing, making sure it refers to the same bag. These are hypothetical situations, not actual offers.

Give evidence for your choice rather than relying on appearance.
Use more than one clue when judging a source.
Be clear when the information is not enough to answer the question.

A simple source check

Question to ask	What to look for
Does it fit my goal?	Information that answers my specific question.
Who provided it?	A named person or organization.
Can I understand and check it?	Clear details, including a date when it matters.
Does another source agree?	A suitable source that covers the same item or question.

Worked example

Example 1: Checking a price source

Mina’s goal is to save for a particular board game. Source A is a store page that names the game, shows a listed price, and gives a date. Source B is an undated social-media comment saying, “That game is around CAD 30.” Which source is more useful for checking the listed price, and why?

Hypothetical source-check comparison

Hypothetical information only. The bars count useful source details for this question: named item, price information, and date. They are not prices or ratings.

Keep the question in view
Mina wants the listed price of a particular game. A useful source needs to refer to that game and give price information.
Compare the details
Source A names the game, gives a price, and provides a date. Source B gives an approximate amount but does not identify a date or show who can confirm the claim.
Choose with a reason
Source A is more useful for Mina’s question because it gives specific, dated information from the store listing. Mina can still check another suitable source if she wants to confirm that the listing is current.

Answer: Source A is more useful for checking the listed price because it names the game and gives a dated price. The comment in Source B is vague and undated.

Check: A source can be useful for a listed price without answering every question about the game.

Worked example

Example 2: Notice a source’s purpose

Arjun wants information about saving for a school trip. A bank page explains its savings account and clearly names the bank. A social-media post says, “This account is the best choice for everyone,” but gives no details. Which source should Arjun investigate first, and what should he keep in mind?

Hypothetical source-detail comparison

Hypothetical comparison of details stated in the example, not a rating of the services. One point is counted for each: source identified, details provided, and connection to saving.

Check which source fits
Arjun’s goal is to save money. The bank page is about a savings account, so it connects to the goal. The post makes a broad claim but gives no details to check.
Consider who made it
The bank identifies itself as the source. It may provide useful information about its own account, but it also has a reason to encourage people to use its services.
Decide what to do next
Arjun should investigate the bank page first because it gives information about the account from the bank. He should read what it actually says and compare it with another suitable source or ask a trusted adult if he needs help understanding it.

Answer: The bank page is the better source to investigate first because it is connected to the goal and identifies who provided it. Arjun should remember that the bank is discussing its own service and check that the page answers his question.

Check: A source’s purpose is a clue to consider, not automatic proof that its information is false.

Worked example

Example 3: Resolve conflicting information

Leah wants to know the listed price of a specific backpack. One dated store page lists it as CAD 24. A second dated store page lists a backpack with the same name as CAD 28. Neither page explains whether the backpacks are the same version. What should Leah do before using either price for her goal?

Hypothetical listed prices

Hypothetical values supplied in the problem. The chart shows that two dated listings differ; it does not show that the backpacks are the same version or that either price is current.

Notice the mismatch
Both pages are dated and name a backpack, but the prices differ. The example does not establish that the two listings describe the same version.
Check what each source covers
Leah should compare the item details and dates. If the pages do not make clear whether the backpacks match, the prices cannot yet be compared fairly for her question.
Seek clarification
Leah can check a more specific listing or ask the store to clarify which backpack each price refers to. Until then, she should not treat either price as confirmed for the exact backpack she wants.

Answer: Leah should check whether both listings refer to the same backpack version and clarify any missing details. The different prices alone do not show which source answers her question.

Check: A date helps, but the source must also refer to the right item.

Common mistakes and how to avoid them

Trusting a source because it looks official or confident.

Correction: Check who provided it, what it says, and whether it fits your question.

Choosing the lowest price without checking what item it describes.

Correction: Make sure the sources refer to the same item and relevant details.

Assuming a source is false because it has a purpose, such as selling a product.

Correction: Notice the purpose, then judge the information using its details and other suitable sources.

Treating an undated claim as current.

Correction: Look for a date or check with the source before relying on time-sensitive information.

Lesson summary

Start with a clear financial goal and question.
Use sources that provide information connected to that question.
Check who provided the information, how clear it is, and when it applies.
Notice the source’s purpose and compare other suitable sources when possible.
If sources conflict or leave out important details, check further before relying on them.

Check your understanding

Question 1

Sam wants to know the listed price of a particular pair of shoes. Which source is the best starting point?

A dated store page naming that pair and showing its price
An undated comment saying shoes are usually inexpensive
A page about how shoes are made
A friend’s guess about the price

Show answer and explanation

A dated store page naming that pair and showing its price

The dated store page names the item and gives the price information Sam needs. He should still check that the listing applies to the pair he wants.

Question 2

A website gives a price but does not name who posted it or when it was posted. What is a sensible next step?

Use it because every website price is reliable
Check a suitable source that identifies the item and provides clearer, dated information
Assume the price is the lowest available
Share the price as confirmed

Show answer and explanation

Check a suitable source that identifies the item and provides clearer, dated information

The missing source and date make the information hard to check. A clearer suitable source is a better next step.

Question 3

Two dated pages give different prices for an item with the same name. What should you check first?

Whether both pages refer to the same version of the item
Which page has the brighter colours
Which price is lower
Whether the pages use short sentences

Show answer and explanation

Whether both pages refer to the same version of the item

The pages need to describe the same item before their prices can help answer the same question.
