Unit 4E: Modelling effects on screen Section 7: INTEGRATED TASK
Objectives
Children should learn:
to write repeating procedures to produce a desired outcome
Activities
Outcomes
Children:
Explain to the class that they will create a number of 'crystal flowers' on screen. Tell them that they will need to write a number of procedures, such as square, rectangle, triangle, pentagon, and that they will combine the shapes into a larger procedure; the larger procedure will allow them to rotate the shapes 360 degrees and produce a flower. An example procedure might be: repeat 36 [square, right 10] which would produce 36 squares with a rotation of 10 degrees in between, producing a flower effect.
Ask children to work in pairs to create their own flowers and get them to print out their work. They could colour in their flowers and produce a garden display for the classroom.
learn how to write procedures using standard commands
learn to combine procedures to produce a desired outcome
Points to note
Extension work could include using more than one shape to produce a flower, for example a square and a triangle rotated. Some children may need example 'flowers' to get them started.
Children will need to know that 360 degrees produces a full turn.
