Lesson plan for teaching some of the key computational thinking skills in primary schools. Key stage 2 plan!!

1. Children will create a dance video &
recognise different actions being
created in order to identify the
structure of an algorithm. They will
use the Scratch block cards to
create an unplugged algorithm.
To be able to create a sequence of
movements
To be able to create an unplugged
algorithm
Children will video their dance
routines; they will use Scratch block
cards to decompose their routines
further to create a structured algorithm
that will be at its most efficient.
Learners will work in pairs and use
their videos to think about the
algorithms. They will be able to watch
videos back in the future to revise
their ideas.
• Digital leaders or gifted & talented children could be paired with those
who are less confident
• Higher learners could be challenged by transferring their unplugged
algorithm to Scratch on the computer
Algorithm
Decomposition
Evaluation
Generalisation
Learners will engage in discussion
about decomposition and creation of
the algorithm; the teacher can
observe discussions & ask open-ended
questions. The children can
present their unplugged algorithms
to the class and they will be
questioned to rectify misconceptions
and highlight their understanding.
Remix This Dance
Learning Episodes Homework
Children will watch BareFoot
Decomposition video & discuss the
key features of decomposing.
Teacher will set a scenario to make a
sandwich & children will need to
explain, how to do so. This can be
discussed.
Children will record their dance
routines. They will use the Scratch
block cards to put this routine into an
algorithm that can be used on the
Scratch website. Children can swap
algorithms & try out each others; peer
assessing to highlight positives &
improvements.
Children go home and create a
video or poster explaining
decomposition. This helps them
apply their newly-learnt knowledge.
