Enterprise Island You have just saved enough money to start your own Lobster business, and will need to decide where to place your pots each night. ‘Outer Pots’ are placed further out at sea, and usually catch the more lobsters, but in bad weather can be washed away and lost at sea. ‘Inner Pots’ usually catch less but are safer in bad weather. Facts and Rules 1.You begin with 6 pots. 2.You can buy more/replacement pots for £20 3.You will earn £20 for each large catch, and £10 for each small catch. 4.You must record where you are going to place your pots on the record sheet, without knowing about the weather situation. 1 Weather Warm, clear night 2 Weather Cloudy and light breeze Pots All safe Pots All safe Catch Outer – large catch in each Inner – small catch in each Catch Outer – small catch in each Inner – small catch in each 3 Weather Strong breeze but clear sky 4 Weather Hurricane Pots Outer – half lost at sea Inner – all safe Pots Outer – all lost at sea Inner – half lost at sea Catch Outer – large catch in each remaining pot Inner – small catch in each Catch Outer – no catch Inner – no catch 5 Weather Driving rain, strong wind 6 Weather Calm and warm Pots Outer – half lost at sea Inner – all safe Pots All safe Catch Outer – no catch Inner – small catch in each Catch Outer – large catch in each Inner – large catch in each Score Sheet for Enterprise Island Day Pots owned Pots placed Outer Inner Catch Large Small Amount earned Pots lost Monday Tuesday Wednesday Thursday Friday Total Profit for 5 days …………………………………………….

In the days of steam it took one hour 30 mins to get from Liverpool Street to Stanstead. That has now been cut to 93 minutes. More than half English 11-year olds have below average reading skills. Maths is magic Take the number of brothers you have, and multiply by 2. Add 5 to the result. Multiply by 5. Now add the number of sisters you have. Multiply the result by 10. Finally add the number of pets you have. What number do you have? Think of ways in which you may use these ideas to help develop numeracy skills • As a subject teacher • As a form tutor.
