The Roller Coaster 2

Ted says the engine of Fiz's wheelchair is getting too hot, as she's been pulling too many passengers on the roller coaster. Ted says she can tow no more mass than the Elephant. He suggests checking the weight of each animal with a see-saw. The Elephant gets bored as everyone gets checked against him so they replace him with blocks and compare weights, finding out that some of the passengers together weigh less than the Elephant. It is proved rather dramatically that Baby Bunting weighs less than the Elephant.

The sixty Number Crew programmes bring maths to life for 5 to 7 year olds, providing an entertaining and imaginative world for children to enjoy and explore maths. The action takes place aboard an unusual cruise ship, the SS Mathematical, where the human crew do their best to look after a collection of animal passengers.

In each programme the crew encounter a mathematical problem. Viewers are encouraged to join the Number Crew in learning the mental strategies and skills they need to solve the problem. A rich mixture of 3-D and 2-D animation, story, song, spectacular studio sequences and real life images combine to make a very successful and popular series.
