Shapes and Crystal Flowers KS2: Use repetition in programs

scripting area blocks pallete stage Which blocks come from which script areas? Hint look at the colour! Helpsheet

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

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

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

Nested loop. Why does this not change the shape?

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

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

Nested loop. Challenge can you make a crystal flower that is different? What will your inner shape be?
