CONCEPT SEQUENCES

All 10 research- and curriculum-based Concept Sequences have both an Empirical and a Logical Basis, and explicitly uncover links between concepts.
The Empirical Basis means that later Levels are both harder than and also include earlier Levels. The Logical Basis means that specific earlier Levels
are prerequisites for specific later Levels. The videos linked here take you through every concepts’ learning sequence.
