Things come back
Shapes, colors, sounds, or dance steps that come back in the same order make a pattern.
05LOOPS · PATTERNS
Spot the pattern.
Before PyBot writes loops, it looks for patterns: shapes that come back in the same order.
LOOK FIRST
A pattern is a part that repeats.
Find the core
The core is the smallest part that repeats. In circle, square, circle, square, the core is circle, square.
A loop repeats the core
Draw the core 3 times and you have the whole pattern. That is what a loop does!
3 times
YOUR TURN
Read the shapes.
Try each tiny question. A wrong answer becomes something to review.

Fix the pattern
One shape breaks the pattern. Tap it to change it until the pattern is right.
Fix the long pattern
Two shapes break this pattern. Find the core first, then tap the wrong shapes to fix them.

BIG IDEA
A loop is a pattern: one core, repeated.
Next, you will write that pattern in Python with for.
