Lesson begins with

Effective lessons start by connecting with students’ prior knowledge. This activates memory; builds bridges between old and new concepts; and increases comprehension. Teachers may use brainstorming; questions; or short reviews to recall earlier lessons. This approach aligns with constructivist learning theory where new knowledge is built on existing foundations. If prior knowledge is not activated; students may face difficulty understanding new material. Good lesson planning always includes an introduction that links past learning with present objectives.
