Display a first-quadrant grid as pupils settle, then extend both axes through zero live on the IWB — push both lines out past zero so the new regions appear. Take two or three hands-up answers, not open call-outs. Don't name the word "quadrant" yet — let pupils describe "below" and "to the left" in their own words first.

Reveal one term at a time, pausing visibly before each so the three ideas don't arrive at once. First point to the origin and say its name and co-ordinate aloud: "zero, zero — the very centre." Pause.

Next, trace the quadrant numbering with your finger: top-right is I, then sweep anticlockwise. Pause. Then walk the four points one at a time, reading the signs: quadrant I is (+,+), quadrant II is (−,+), quadrant III is (−,−), quadrant IV is (+,−). Pause before each reveal and ask the class to predict the signs.

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

Ask the class to read the signs before the point is plotted, then plot to confirm. Revoice a strong answer: "both numbers negative, so it has to be quadrant three." Watch for the common slip of reading the y sign first — keep saying x sign, then y sign. Rotate four pupils to the board.

This round is the practice bank — 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 final challenge is the high-ceiling one: a point on an axis (like (0, 4) or (−3, 0)) belongs to no quadrant because one co-ordinate is zero. Let the class debate it before checking. Revoice: "if a number is zero, the point sits on the line, not in a corner."

Recap the sign patterns quickly by pointing to each quadrant and taking hands-up answers for the signs. Flag the next lesson moves from naming quadrants to plotting negative points precisely.
