My everyday activity which corresponds to algorithms/programming is the children’s morning/afternoon classroom routine. I would introduce this activity by modelling and scaffolding how to construct this algorithm (eg showing an example I have pre-made). Students will then have the opportunity to extend/modify this flowchart collaboratively before having the chance to create the lunch routine or another provided example.
Algorithms can also be designed for free play. When and if students ever feel like they are unsure what to do with the spare time they have (e.g. when finishing tasks early), they can follow a decision making algorithm that helps them decide what to do, e.g. read a book, tidy their desk drawer, solve a puzzle, etc.
