Take three hands-up answers, not open call-outs. Display real photos of the three objects if you have them, otherwise sketch them on the board.

Steer the talk toward two ideas the lesson needs: straight sides and corners. Don't name the shapes yet, that comes in Watch and Notice.

The shapes are shown already sorted into side-count groups on the slide. Count aloud as you point to each group.

Triangle: 3 straight sides, 3 corners. Touch each side and corner as you count. Introduce vertex, and vertices for more than one, as the proper word for corner.

Square: 4 sides all the same length, 4 vertices. Name any four-sided flat shape a quadrilateral; a square is a special one with all sides equal.

Pentagon: 5 sides, 5 vertices. Link penta to five if the class enjoys word-roots.

Hexagon: 6 sides, 6 vertices.

Let the class notice sides always equal vertices themselves. Vocabulary to lock in today: vertex, vertices, quadrilateral.

This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.

Show one shape card at a time. Ask a pupil to count the sides aloud before dragging. The class confirms the count, then the pupil drops it in the matching group.

Deliberately include a few rotated shapes so pupils learn that turning a shape does not change how many sides it has. Revoice strong reasoning: so even though the pentagon is upside down, it still has five sides.

These are the practice questions — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.

The challenge bank rises in difficulty. For the last round, say each shape's name aloud as it appears (rhombus, trapezium) and point out that the square, rhombus and trapezium have four straight sides, so they share the 4 sides group even though their names differ — counting sides gets you to the group; the name needs a second look.
