Shapes & Crystal Flowers Repetition

RESOURCE OVERVIEW:

In this activity pupils design algorithms to draw patterns made of simple shapes before writing a Scratch program to draw their shapes. In doing so, they learn about repetition.

PUPIL OBJECTIVES:

• I can write a program that uses a repeat command.
• I can explain what the repeats in my program do.

TEACHING ASSESSMENT OPPORTUNITIES:

• Informal teacher assessment of progress during the lesson. Key pupil knowledge and skills to identify include:
  • Do pupils understand the concept of repetition?
  • Do pupils see the benefit of using repetition commands?
  • Can pupils use repletion commands to draw shapes?
  • Can pupils nest repletion commands to create crystal flowers?
  • Can pupils debug their programs when required?
• Formal, summative assessment of Scratch projects (pairs).
• Peer assessment and feedback of crystal flower programs during the plenary.

LESSON TIMING: 60 min
