Utajifunza
- Follow a sequence of movement instructions on a grid and predict where it ends.
- Write a sequence of instructions to reach a target, and test it.
- Find and fix a mistake in a sequence of instructions.
Fasili
- An algorithm is a precise list of steps that can be followed to complete a task.
- A bug is a mistake in an algorithm that makes it do something unintended.
Nadharia
- Changing the order of the steps can change the result.
- Instructions must be precise enough to be followed without guessing.
Mawazo potofu ya kawaida
- Thinking a robot or computer 'knows what you mean' when instructions are vague.
- Believing there is only one correct algorithm for a task.
Inaelekea kwa
