Teaching guide
Design and describe step-by-step algorithms that sort and classify shapes by their attributes.
Write the sorting rule as a clear sequence of yes/no questions (for example 'does it have 4 sides?'), test it on real shapes, and trace how each shape moves through the steps.
Overlapping or incomplete questions that leave a shape with no path, and steps written in an order that changes the outcome.
