2S - Computing

Lesson: Information and communication technology

This lesson focused on sequences and guided the children to consider the importance of the order of instructions within a sequence. Children created sequences using the same commands in different orders. They then tested these sequences to see how the different orders affect the outcome.

The children were reminded that sets of instructions can be thought of as algorithms; an algorithm is a precise set of ordered instructions, which can be turned into code on a computer.

Children then created different algorithms using four given arrow instructions (forwards, forwards, left turn, right turn).  They had to arrange the four arrows in different orders to make four different algorithms for their partner to follow.
