The first activity was designed to

• introduce infinite sequences as infinite processes that produce an infinite stream of numbers,
• introduce mathematical operations such as doubling each element in a sequence that treat infinite sequences as objects to be operated upon,
• introduce an operation that starts with an infinite sequence and produces two infinite sub-sequences, and
• encourage the children to reflect upon the seemingly paradoxical nature of infinity.
