Equipment. One pack of cards with picture cards removed.
The black cards are positive numbers and the red cards are negative numbers. Ace is one. Each player is dealt 2 cards. Each player chooses whether to accept a third card from the dealer. The object is to make the total of the cards in your hand as close to zero as possible. The hand shown on the right is +7.
Each round the winner scores zero and losing players score the difference of their hand from zero. The pictured hand would score 7 points.
Play continues until one player reaches 50 points. The winner is the player with the least points.

An arcade style “astroids” game where you have to shoot the decimals in the right order.
2. Write down the last two digits of the year. (eg 74)
3. Divide by 4 and ignore the decimal part or remainder. (eg 74 ÷ 4 = 18)
4. Add together the answers to 1 and 2 (eg 74 + 18 =92)
5. Add the number of the day of your date of birth. (eg 92 + 25 =117)
6. Add a number according to your month of birth as follows.
JAN 1 (0 for Leap Year) How do you tell if a year is a leap year?
FEB 4 (3 for Leap Year) How do you tell if a year is a leap year?
(eg 117 + 6 for Dec = 123)
For years beginning 18.. add 2
For years beginning 19.. add 0
For years beginning 20.. add 6
(eg 123 +0 = 123)
Divide your answer by 7 and work out the remainder.
(eg 123÷ 7 = 17 remainder 4)
The remainder gives the day of the week you were born on.
1 = Sunday
6 = Friday
7 = Saturday
(s0 25.12.74 was a Wednesday)
Leap years have an extra day in February, so there are 29 days in February and 366 days in a leap year. Lots of people believe that if a year is divisible by 4 it is a leap year. However there are some exceptions to this.
To work it out follow these instructions.
1. Write down your house number.
2. Double it.
3. Add the number of days in a week.
4. Multiply by 50.
5. Add your age.
6. Subtract the number of days in a year. (not a leap year)
7. Add 15
The answer is your teachers house number and their age!
Can you explain why this works?
Do you understand those letters that come through the door offering you a credit card? Have a go at this exercise to find out more.
Here is a worksheet version.
(I have used Sainsbury’s Bank as an example of a typical credit card provider- this exercise does not insinuate that Sainsbury’s Bank is any worse than other credit card providers.)
Many people on a low income are not able to open a bank account. If they need to borrow money they can be offered loans with massive rates of interest. This exercise looks at how to calculate interest rates and compares different ways of borrowing money.
The video mentions two businesses in particular. Wonga.com and Quick Quid both charge interest rates in excess of 2000%. Do you know of higher rates of interest? Please comment below to name and shame the loan sharks!
The same exercise is here in worksheet format.
The Joseph Rowntree Foundation research into the minimum income standards for the UK. The Minimum Income Standard for the UK shows how much money people need, so that they can buy things that members of the public think that everyone in the UK should be able to afford.
- Figures are based on public views about a minimum standard that nobody should fall below.
- It does not show you what you require to meet all your individual needs, and is not suitable for use as a personal budgeting tool.
By entering a few details about your circumstances you can compare your income with the MIS, and see how this is made up. For instance my children are now all grown up and have left home, so I live with my wife. When I have entered details about my rent/mortgage. gas/electric/water bills etc it tells me the minimum income I require is £23,099. They break this down into how much I need for food, alcohol. council tax, clothing etc. It makes very interesting reading!
Go to http://www.minimumincome.org.uk/ and enter your details to see what it suggests for your household.
Try this exercise to find out about a single persons minimum income. It will also help you to calculate percentages.
Many people living in poverty are being ripped off with massive interest rates. There is an interesting blog article here which explains how people who can’t get bank accounts and are trying to survive on benefits sometimes see no alternative but to use door step lenders or shops that offer instant credit but then charge extortionate interest rates.

This exercise will help you understand “units” of electricity and help you work out how much electricity different things use.
