Shapes and Crystal Flowers KS2: Use repetition in programs

Stage Blocks Pallete Scripting Area Which blocks come from which script areas? Hint look at the colour! Helpsheet

Can you use the repeat block to make this code draw a square? Helpsheet 2

What is the difference?

Challenge Why are repeats (or loops) useful when we program?

Today we are learning about: Programs & Repetition I can write a program that uses a repeat command I can explain what the repeats do in my program

Why are repeats (or loops) useful when we program? Challenge Drawing a Pentacontagon - 50 sided shape Can you see a mistake? Why are repeats (or loops) useful when we program?

Nested Loop Why does this not change the shape?

Nested Loop What is the inner shape? How many times does it draw this shape? Why are loops useful?

Nested Loop What is the inner shape? How many times does it draw this shape? Challenge: Can you make a crystal flower that is different? What will your inner shape be?

Nested Loop Challenge: Can you make a crystal flower that is different? What will your inner shape be?
