Number of players 2-4

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.

1. Write down your date of birth using 6 figures. So 25th December 1974 would be 25.12.74

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

2= Monday

3= Tuesday

4= Wednesday

5= Thursday

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.

If the year divides exactly by 4 it is a leap year, UNLESS
it is a new century. (ends in 00)
If this is the case if it divides exactly by 400 it is a leap year, if not it is not.
Was 2012 a leap year?
2012÷4 = 503. YES!
Will 2018 be a leap year?
2018÷4 = 504 r2 NO!
Was 2000 a leap year?
2000÷400 = 5 YES!
Will 2100 be a leap year?
2100÷400 = 5 r100 NO!

4.  Multiply by 50.

5. Add your age.

6. Subtract the number of days in a year. (not a leap year)

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!

minimum income standardThe picture shows the results for a single person.

Go to 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.
