understand what algorithms are; how they are implemented as programs on digital devices; and that programs execute by following precise and unambiguous instructions.
create and debug simple programs
LO: To write instructions to complete a task.
Using last lessons programs/envelopes can children follow the instructions others have written?
Swap envelopes between groups and follow the instructions - what problems do we encounter if we don't follow the instructions exactly. Explain that computers/Beebots/robots just follow the instructions we give them, they can't think for themselves - they can't see where something is going wrong like humans can!
