Introduction

Financial Literacy — Budgeting, Saving, and Investing is an important Grade 7 math skill because students are moving from simple answers toward explaining how the math works.

In this lesson, students use models, real questions, worked examples, practice problems, and two online quizzes to build confidence with financial literacy — budgeting, saving, and investing.

What Is Financial Literacy — Budgeting, Saving, and Investing?

Financial Literacy — Budgeting, Saving, and Investing means choosing a model, naming what each number means, and explaining the strategy.

The goal is not only to get the answer. Students should be able to show the idea, explain the strategy, and check whether the answer makes sense.

Understanding Financial Literacy — Budgeting, Saving, and Investing

Before solving, students should slow down and decide what each number, shape, unit, or label represents.

  • Read the question carefully and identify what is being asked.
  • Choose a model, equation, table, or diagram that matches the situation.
  • Solve one step at a time and keep units or labels attached.
  • Use the answer explanation to check that the result makes sense.

Visual Models

Visual Model 1

Question: A budget is shown in the pie chart below. The budget totals \($1{,}200\) per month. How much money is budgeted for rent?

Visual Model 1

  • A. \($180\)
  • B. \($240\)
  • C. \($600\)
  • D. \($720\)

Why it works: Rent \(=50\%\times$1{,}200=0.50\times1200=$600\).

Answer: \($600\)

Visual Model 2

Question: An investor compares two savings accounts over one year using the bar chart below. If Account A earns \(4\%\) simple interest and Account B earns \(6\%\), which account grew more after 6 months?

Visual Model 2

  • A. Account A
  • B. Cannot be determined
  • C. Both grew equally
  • D. Account B

Why it works: Account B at \(6\%\) earns more growth than Account A at \(4\%\) over the same period. The chart reflects this with the higher bar for Account B at Month 6.

Answer: Account B

Worked Examples

Example 1

Question: A teen saves money to buy a gaming console. The table shows their savings each month: If the pattern continues, how much will they save in May?

MonthJanuaryFebruaryMarch
Savings$25$50$75
  • A. \($100\)
  • B. \($175\)
  • C. \($150\)
  • D. \($125\)
  1. The pattern increases by \($25\) each month: Jan \($25\), Feb \($50\), Mar \($75\), Apr \($100\), May \($125\).

Answer: \($125\)

Example 2

Question: A budget visualization shows a number line allocating monthly income of \($2{,}000\): What percentage of income is allocated to wants?

Example 2

  • A. \(20\%\)
  • B. \(25\%\)
  • C. \(30\%\)
  • D. \(50\%\)
  1. Wants span from \($400\) to \($1000\), which is \($600\) of \($2000 = 0.30 = 30\%\).

Answer: \(30\%\)

Example 3

Question: Liam's monthly budget allocates \(40\%\) to expenses, \(30\%\) to savings, \(20\%\) to investments, and \(10\%\) to charity. If his monthly income is \($2{,}500\), how much does he invest each month?

  • A. \($250\)
  • B. \($1{,}000\)
  • C. \($750\)
  • D. \($500\)
  1. Investments \(=20\%\) of \($2{,}500=0.20\times2500=$500\).

Answer: \($500\)

Real-World Word Problems

Problem 1

Question: Jasmine earns \($1{,}200\) per month. She puts \(12\%\) into a savings account. How much money does she save each month?

  • A. \($144\)
  • B. \($240\)
  • C. \($360\)
  • D. \($480\)

Why it works: Savings \(=12\%\) of \($1{,}200=0.12\times1200=$144\).

Answer: \($144\)

Problem 2

Question: A student's part-time job pays \($600\) per month. After saving \(25\%\), how much money does the student have left to spend?

  • A. \($150\)
  • B. \($300\)
  • C. \($400\)
  • D. \($450\)

Why it works: Amount left \(=(100\%-25\%)\times$600=75\%\times600=0.75\times600=$450\).

Answer: \($450\)

Common Mistakes

  • Rushing before identifying what the numbers represent.

  • Skipping the estimate or reasonableness check.

Strategy Tips

  • Underline the question being asked.
  • Use a model before jumping to computation.
  • Write an equation that matches the story or picture.
  • Explain the final answer in a sentence.

Question 1

Answer: \($28\)

Savings \(=35\%\) of \($80=0.35\times80=$28\).

Question 2

Answer: \($540\)

Other expenses \(=(100 - 50 - 20 - 15)\%=15\%\) of \($3{,}600=0.15\times3600=$540\).

Question 3

Answer: \($20\)

Option 1 interest: \(3\% \times $1{,}000 = $30\). Option 2 interest: \(5\% \times $1{,}000 = $50\). Difference: \($50 - $30 = $20\).

Question 4

Answer: \($120\)

Needs + Wants \(= 50\% + 30\% = 80\%\) of \($600 = $480\). Remaining for savings and other \(= 100\% - 80\% = 20\%\) of \($600 = $120\).

Question 5

Answer: \($50\)

Simple interest \(=P\times r\times t=$1{,}000\times0.05\times1=$50\).

Question 6

Answer: \($160\)
