Australian Curriculum Money: Book 3 by Teacher Superstore

TEACHERS NOTES

YEAR

Create simple financial plans (ACMNA106)

INTRODUCTION At this level, most students would have an understanding of our money system and our notes and coins. Building on from this, students will be asked to look at and question money, finances and the use of budgets. Students will see a variety of financial plans and budgets that are used to help people manage and control their money. They will discuss what a budget is, how it can be used and for what purpose. Students will look at simple budgets and will have the opportunity to set up a individual and group budget in order to assess its usefulness. Students will be asked to question how and why shops still use amounts that do not end in zero or five cents and what happens to these amounts at the cash register. Demonstrate how prices are rounded up or down to the nearest five cents as we no longer have one and two cents coins in Australia. Show students how cash registers, calculators and computers are used to add, subtract, multiply and divide monetary amounts. Give students the opportunity to solve many different money problems using both written methods as well as digital technologies.

discount. Introduce and define the term GST (Goods and Services Tax), what it is and why we have it in Australia. Instruct students to look at receipts and invoices with GST and see how much GST is included on items. Explain what items do not have GST on them and why. Give students a list of goods and ask them to calculate the 10% GST on them. Discuss whether the GST can change. Explain that if a new government is elected or the country needs to collect more tax then the GST may increase.

Links to other areas of the curriculum Humanities and Social Sciences: Create a class project where the class can raise money for a charity group. Investigate and plan who they will raise the money for, how they will raise it—for example, a walkathon; a trashand-treasure or a cupcake stall—and what profit they hope to achieve and donate in the end. Work out a budget which can be used to help them raise the money.

Introduce the concept of the Goods and Services Tax (GST) which we have in Australia. Explain what it is and how it is calculated. Allow students to identify the GST component of invoices and receipts. As most GST is 10% talk about percentages and how they relate to money. Instruct students to calculate 10% off various amounts and solve problems involving the use of percentages while making connections between equivalent fractions, decimals and percentages.

English: © R. I . C.Pu bl i cat i ons Creating a budget •f orr evi ew pur posesonl y•

Look at the words associated with a budget and define them; e.g. budget, profit, loss, GST, income, expenses, rewards, costs, needs, wants etc. Make a list of words that can be abbreviated such as GST and discuss why we abbreviate words like this.

Look at some examples of budgets and interpret them. Imagine you need to set up a class fundraiser. Demonstrate to students how they would set up a budget to work out how much they need to raise. Explain that when setting up a budget you need to account for all costs and be able to estimate how much money will be coming in and going out. Discuss and demonstrate how a budget is a useful tool to set up and use for a number of reasons. It can help you save for something, work out how much you spend or calculate how much you can get as a return for goods or a service. Working in groups, plan an event including a budget which allows for expenses and profit involved in a fundraising event. Use a written method to budget as well as looking at other options available through the internet such as a spreadsheet program like Excel®. Assist students to set up their own individual budget, keeping account of money they have coming in as well as expenses they may have over a set time frame, such as one month. Give students the opportunity to set up their budget on a computer using a basic spreadsheet. This will give them an insight into how they use their money and if they need to reconsider how much they save or spend.

Technologies: Look at methods for creating budgets using the computer. For example, tables can be used in a word document. Spreadsheets can be created using Excel®. Look at examples of budgets using the internet. Trial a simple budget using some of the following tools on the computer. <www.mathsisfun.com> – Money—personal budget <www.simpleplanning.com> – Reading and looking at how to set up simple budgets. View the ABC’s Behind the news story ‘GST changes’ and discuss and answer questions about the GST such as: • what is tax and what is it used for? • what does GST stand for? • what percentage of GST do we currently pay in Australia? • name some products that do not have GST. • name some products that do have GST. • what changes could the government make to GST in the future?

Identifying and calculating GST Demonstrate to students how to relate money (decimal numbers) to fractions and percentages. Show them how to calculate 10% of a given amount in order to find a

Rounding up or down

In Australia our smallest coin is five cents, therefore all amounts paid in cash need to be rounded up or down to the nearest five cents. The rules are: • amounts ending in 0c or 5c do not change • amounts ending in 1c or 2c are rounded down to the nearest 0c; e.g. 42c = 40c • amounts ending in 3c or 4c are rounded up to the nearest 5c; e.g. 64c = 65c • amounts ending in 6c or 7c are rounded down to 5c; e.g. $2.87 = $2.85 • amounts ending in 8c or 9c are rounded up to the nearest 10c; e.g. $1.29 = $1.30 For each amount, tick the box to show whether it needs to be rounded up, down or remain the same. Find and add five more prices from a catalogue. Amount

TEACHERS NOTES

YEAR

Investigate and calculate percentage discounts of 10%, 25% and 50% on sale items, with and without digital technologies (ACMNA132)

INTRODUCTION This outcome and level is all about immersing students in percentages. At this level students should have a relatively good grasp of working with decimal numbers and money. They will use their knowledge of decimal numbers and fractions and relate this to percentages. Building on their previous knowledge of financial mathematics, students can have discussions on the need to budget, the role of tax and GST, and how shops use percentages to add or reduce costs for consumers. Students will be given the opportunity to focus on real-life money situations such as working out costs and percentages using the written method as well as calculators or computers, and they will come to realise that percentages are part of everyday life. Interest rates on loans and savings are another way of using percentages to calculate what we may owe or have owed to us.

Relating fractions, decimals and percentages

off an amount they can either calculate 10% then double that amount or they can think 20% is the same as 15 , so calculate 15 of the amount. Both methods are correct and get the same answer, but students may prefer to use one over the other.

Students will notice and discuss how fractions, decimals and percentages are all related as they are all parts of whole numbers. If they were to see a sign in a store saying 50% off they would realise that 50% is also half the amount. They will also need to relate fractions to decimal numbers, as these decimal numbers are used to represent our money system.

When solving problems relating to calculating a percentage off an amount, it is important to point out to students that once they have worked out the percentage they must then subtract this from the original price to find the new discounted cost. Alternatively, they may be required to add 10% to a cost after they have calculated it, such as adding 10% GST to an amount.

Highlight and discuss with students that the non-significant zero that can be omitted when writing a decimal number needs to be included when representing a monetary amount; e.g. 4.20 can be written as 4.2 when expressed as a decimal number but as an amount should be expressed as $4.20.

Interest rates on loans are also worked out as a percentage of what is borrowed, therefore students will have the opportunity to calculate what would need to be repaid after the interest rate is calculated and added on to the borrowed amount. Interest rates that are charged on credit card loans are generally at higher rates because they are usually for a shorter term. Allow students to calculate various percentages using the written method and using digital technology (a calculator or computer).

There will be a crossover of concepts when discussing fractions, decimals and percentages, and students will draw on their knowledge from other mathematical outcomes such as Make connections between equivalent fractions, decimals and percentages (ACMNA131) and Multiply and divide decimals by powers of 10 (ACMNA130) . These concepts are evident when students look at marketing techniques stores often use such as multibuys. Students will be asked to divide these multibuys to see if there is a saving. Alternatively, they may be required to multiply a cost by multiples of 10. Demonstrate to students how the digits of a number move columns to the right or left when we divide and multiply by powers of 10.

Links to other areas of the curriculum Humanities and Social Sciences: Allow students to investigate how percentages are used in the retail world. Look at marketing techniques and how shops use percentage-off sales and multibuys to encourage consumers to shop and spend more.

Calculating percentages

Ask students to investigate the cost of borrowing money from a bank (a loan). Students imagine they want to buy a car and borrow $10 000 from a bank. What total amount would you end up paying after you added interest charged?

A large part of our lives when dealing with money involves being able to calculate percentages. We use percentages to pay tax (10% GST), add interest to a loan, receive a percentage of an income, take a percentage off an amount for a sale item etc. After students have had the opportunity to convert fractions and decimals into percentages they will begin to understand how to calculate the percentage of an amount.

Investigate our decimal currency to answer questions including how dollars and cents became our currency and when and why we replaced our old currency of pounds, shillings and pence.

Show students how to calculate 10% of an amount and see if they notice that when they move the digits one column to the right it will give them that 10%; e.g. 10% of $4.50 = 45c. Using their knowledge of fractions they will realise that 25% is the same as 14 , therefore they could calculate 1 of a cost to find the percentage off. When calculating 4 50% off a price, again they will draw on their knowledge that 50% is equivalent to 12 , therefore the price will be halved. Demonstrate to students that when calculating 20%

ISBN 978-1-925431-18-6

English: Look at financial words and terminology such as debit, credit, interest, principal, interest rate, budget, tax, percentage etc. Define these words and look at their origins. Write a story or play about visiting a Boxing Day sale. Investigate old and new sayings that mention money; for example, ‘a penny for your thoughts’.

Multiplying money by 10, 100 and 1000

YEAR

When we multiply an amount of money by 10, each digit moves one column to the left; e.g. 0.05c x 10 = $0.50. If we multiply the amount by 100, each digit moves two columns to the left; e.g. 0.05c x 100 = $5.00. If we multiply the amount by 1000, each digit moves three columns to the left; e.g. 0.05c x 1000 = $50.00. 1. Fill in the table by multiplying these amounts of money by 10, 100 and 1000. Amount

Using calculators to work out percentages

YEAR

1. Use a calculator to find the percentage rate of these amounts. To do this, multiply the amount by the percentage on the calculator. For example: 25% of $300 = press 300 x 25% = $75.00. (a) 10% of $60.00 (60 x 10%) = (b) 30% of $5.00 (5 x 30%) = (c) 40% of $20.00 (20 x 40%) = (d) 25% of $90.00 (90 x 25%) = (e) 60% of $200.00 (200 x 60%) =

(i) 20% of $65.00 (65 x 20%) =

(f) 70% of $50.00 (50 x 70%) =

(j) 50% of $210.00 (210 x 50%) =

(g) 80% of $400.00 (400 x 80%) =

(k) 75% of $300.00 (300 x 75%) =

(h) 30% of $350.00 (350 x 30%) =

(l) 90% of $700.00 (700 x 90%) =

2. What total would you end up paying back if you borrowed these amounts at 2% interest? You will need to add the interest to the amount. You may like to use a calculator. For example: $3000 = $3000 + $60 = $3060.00

1. Calculate the various interest rates of these amounts. 5%

When organisations lend money they normally charge an interest amount in the form of a percentage of the total amount lent. This can range from 2% up to 10%. When lending money you can choose a fixed rate of interest, which means the interest rate does not change, or a variable rate of interest, which means the interest rate changes according to the market values. For example, if you were to borrow $1000 at 3% fixed interest, you would end up paying back $1030 (think 1% of $1000 = $10 x 3 = $30). Alternatively, using a calculator, 1000 x 3% = $30.

Credit cards and interest rates

YEAR

Interest rates on credit cards are usually higher because the loan repayment time is generally shorter than on long term loans. They can be as high as 20%. If a credit card is paid in full by the due date then no interest is added, but if the bill is over the due date then interest is added and calculated daily. 1. Calculate the interest these people owe on their credit card bills below by adding 20% to their bill. (a) Rachel’s total $500.00 + 20%
