Generate one continuous core lesson. Scene descriptions include visual direction, narration and exact on-screen labels. Do not include intro/outro dialogue again. GLOBAL TOMOMOTION PROMPT Premium polished 3D educational animation for Grade 6 Mathematics. Use approved Yuvan and Yuvan references exactly; preserve character designs and voices. No other human characters. Bright clean learning space, warm Indian classroom, teal-and-white cards, readable geometry labels, smooth transitions. Generate narration and visuals together where supported; keep music low. One continuous core lesson, no duplicated intro/outro lines. 16:9 landscape. Do not mention source textbook or publisher. SCENE 0:00–0:30 — ARTWORK AND TOOLS Show simple examples of circles, overlapping circles, straight lines and a face made from circles, matching the artwork examples in the lesson. Transition to a ruler and compass on the table. Yuvan: “Geometric artwork can be made from simple shapes and curves.” Yuvan: “A ruler helps us draw straight lines, and a compass helps us draw circles and arcs.” On-screen: “RULER → STRAIGHT LINES”; “COMPASS → CIRCLES AND ARCS”. SCENE 0:30–1:00 — HOW A COMPASS DRAWS A CIRCLE Close-up of a compass. Show the needle point fixed at one location on paper while the pencil moves all the way around. Keep the centre stationary; only the pencil traces the circle. Yuvan: “The pointed end stays in one place while the pencil moves around.” Yuvan: “That fixed point is the centre. Every point on the circle stays the same distance from it.” On-screen: “FIXED POINT = CENTRE”; “SAME DISTANCE ALL AROUND”. SCENE 1:00–1:35 — SET THE RADIUS TO 4 CM Show compass tips measured against a ruler. Open the compass until the distance between the needle and pencil tip is exactly 4 cm. Then place the needle at point P and draw a full circle. Label the centre P and a segment from P to the circumference as 4 cm. Yuvan: “Set the compass opening to four centimetres. Keep the needle at P and rotate the pencil around.” Yuvan: “Every point on the circle is four centimetres from P.” On-screen: “RADIUS = 4 cm”. SCENE 1:35–2:10 — CENTRE AND RADIUS Zoom into the circle and highlight P, then a line segment from P to a point on the circumference. Yuvan: “The point P is called the centre of the circle.” Yuvan: “And the distance from the centre to any point on the circle is the radius.” On-screen labels: “CENTRE: P”; “RADIUS: 4 cm”. Keep the radius line ending exactly on the circumference. SCENE 2:10–2:50 — ALL POINTS 4 CM FROM P Show point P and several marked points around it, each connected to P by a dashed segment labelled 4 cm. Then reveal the circle passing through those points. Yuvan: “If we mark many points that are four centimetres from P, what shape do they make?” Pause for learner thinking. Yuvan: “Together, all points at this fixed distance from P form a circle.” On-screen: “ALL POINTS 4 cm FROM P → A CIRCLE”. SCENE 2:50–3:30 — TRY IT YOURSELF Show a notebook page with point P. Animate a compass being set to 4 cm using a ruler, the needle placed at P, and a circle drawn. Show the learner prompt. Narration: Yuvan: “Your turn! Mark point P in your notebook.” Yuvan: “Use a compass to draw a circle with radius four centimetres. Check the distance from P to a few points on your circle.” On-screen: “YOUR TURN: CENTRE P • RADIUS 4 cm”. SCENE 3:30–4:00 — RECAP AND HANDOVER Show the finished circle with centre P and radius 4 cm, alongside a small artwork collage of circles and straight lines. Yuvan: “A circle has a centre, and every point on it is the same distance from the centre.” Yuvan: “Now let’s use these ideas to construct artwork: a person, a wavy wave and a pair of eyes.” On-screen: “CENTRE + FIXED RADIUS = CIRCLE”.
