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, crisp black line-art on white paper, readable construction marks and labels, smooth transitions. Show each ruler/compass action clearly and slowly enough for learners to follow. One continuous core lesson, no duplicated intro/outro lines. 16:9 landscape. Do not mention source textbook or publisher.
SCENE 0:00–0:20 — RECALL THE TOOLS
Briefly recap a compass drawing a circle and a ruler drawing a straight line. Show the three target designs side by side: A Person, Wavy Wave and Eyes. Yuvan: “We’ll build each figure from simple lines, circles and arcs.” On-screen: “A PERSON • WAVY WAVE • EYES”.
SCENE 0:20–1:15 — CONSTRUCTION 1: A PERSON
Show the head as a circle, then the straight sides and base of the body. Focus on the curved line forming the top of the body. Show the challenge: choose where the compass needle should be placed and what radius should be used. Demonstrate testing the compass position and radius on a practice sheet, then tracing the curve that joins the top ends of the body. Yuvan: “The head is a circle, but the top of the body is a curve. Where should the compass point go?” Yuvan: “We need to test the compass position and radius so the curve fits between the two sides.” On-screen: “A PERSON: CIRCLE + STRAIGHT LINES + CURVE”; “TEST THE CENTRE AND RADIUS”. Keep the construction exploratory; do not imply a unique compass setting if the source does not specify one.
SCENE 1:15–2:25 — CONSTRUCTION 2: WAVY WAVE
Draw a straight central line AB and label AB = 8 cm. Mark its midpoint X so AX = XB = 4 cm. Use AX as the diameter of the first half-circle above the line and XB as the diameter of the second half-circle below the line. Each half-circle has radius 2 cm. Animate compass centre at the midpoint of each 4 cm half-segment, with radius 2 cm, then trace each semicircle. Yuvan: “The full central line is eight centimetres long. How can we make two matching waves?” Yuvan: “Split it into two equal four-centimetre parts. Each part is a diameter, so the radius is two centimetres.” On-screen: “AB = 8 cm”; “AX = XB = 4 cm”; “RADIUS = 2 cm”. Show the first arc above AB and the second below AB, meeting smoothly at X.
SCENE 2:25–3:25 — CONSTRUCTION 3: EYES
Show the two eye outlines from the lesson. Build one eye as a pointed lens-like outline formed by two matching arcs meeting at left and right tips; then repeat for the second eye. Demonstrate placing compass points at suitable endpoints/centres and maintaining a consistent radius so the upper and lower arcs meet neatly. Add the black circular pupils as separate filled circles. Yuvan: “How can we make both eyes look alike?” Yuvan: “Use the same compass opening and repeat the arc construction for the second eye.” On-screen: “SAME COMPASS OPENING → MATCHING ARCS”; “REPEAT FOR THE SECOND EYE”. Do not invent exact dimensions absent from the source; show the construction logic and matching shape.
SCENE 3:25–3:45 — CHECK THE CONSTRUCTIONS
Show each finished figure. For A Person, check that the curved top meets both body sides. For Wavy Wave, check that the central line is 8 cm, each half is 4 cm, and the two semicircles are identical and face opposite directions. For Eyes, check that both outlines are matching and pupils are circular. Yuvan: “The small measurements help the artwork look balanced.” Yuvan: “And checking the joins helps every curve meet neatly.”
SCENE 3:45–4:00 — QUICK THINK + HANDOVER
Show the three designs with a short learner challenge. Ask: “For the wavy wave, what is the radius if each half-circle has a diameter of 4 cm?” Pause, then reveal “2 cm”. Yuvan: “Now we can use a ruler and compass to make artwork!” Yuvan: “Try making your own design with circles, straight lines and curves.” On-screen: “MEASURE • CONSTRUCT • CHECK”.
MATHEMATICAL ACCURACY
For the Wavy Wave, AB = 8 cm and the two equal half-segments are 4 cm each. Each half-circle has a 4 cm diameter and a 2 cm radius.
The two half-circles must be identical and lie on opposite sides of the central line, meeting at the midpoint.
For A Person, the source presents the curved top as a challenge to explore; do not assert an exact compass centre or radius that is not specified.
For Eyes, preserve the matching lens-like outlines and circular pupils. Demonstrate repeated compass use without adding unsupported fixed dimensions.
Show compass points, pencil traces, endpoints and joins clearly. Keep geometry marks clean and do not allow decorative animation to obscure construction steps.
