Create a premium, clean Grade 6 CBSE/NCERT mathematics animation for Athena Learning Solutions in 16:9 landscape. Mili is the sole guide. Use the attached approved Mili school-uniform image as the character reference. Preserve her recognisable face, warm skin tone, large brown eyes, dark-brown side braid, small gold stud earrings, age appearance and polished 3D character style. Keep the same light-blue collared shirt, navy pleated pinafore with belt and silver buckle, white socks and black Mary Jane shoes throughout this lesson. Do not use the yellow dress or flower-filled braid from the original face reference. Do not redesign her outfit, hairstyle or facial features. Keep her voice and appearance consistent across the opening and ending. Use simple English, a warm clear educator voice, a bright uncluttered classroom/learning space, modern EdTech motion graphics, accurate geometry and large mobile-readable visuals. The sequence headings below are directions within ONE continuous master prompt, not separate prompts. Generate visuals, spoken narration, exact overlays and answer reveals together wherever the current TomoMotion setup supports usable text and audio. Do not add extra dialogue. Do not duplicate Flow Veo opening or ending dialogue in the core narration. If integrated audio is unavailable, use the narration written inside this same prompt as the fallback voice script; do not play duplicate narration.
LESSON TITLE: “Meet the Angle Types”
Keep the visuals and narration synchronized. Show each angle large and clear. The angle arc must mark the intended region. The displayed measure must match the drawn geometry.
SEQUENCE A — RECALL
Visual: Show a right angle with a square corner marker and a straight angle. Then show angle arms opening and closing.
Narration: “A right angle measures 90 degrees. A straight angle measures 180 degrees. Now let’s explore angles that are smaller, larger, or turn beyond a straight line.”
Exact overlay: “WHAT ARE THE FIVE TYPES OF ANGLES?”
SEQUENCE B — ACUTE ANGLE
Visual: Close an angle to show accurate examples of 30°, 45° and 70° in different orientations.
Narration: “An acute angle is greater than 0 degrees and less than 90 degrees. It is smaller than a right angle.”
Exact overlays: “ACUTE ANGLE”; “0° < angle < 90°”; “30° • 45° • 70°”
Ask: “Does an angle stop being acute when we turn the whole picture?” Pause. Narration: “No. Its direction can change, but its measure stays the same.”
SEQUENCE C — RIGHT ANGLE
Visual: Show accurate 90° angles upright, tilted and diagonal. Mark each with a square corner symbol.
Narration: “A right angle measures exactly 90 degrees. It does not need to look like an upright letter L. Its measure is what matters.”
Exact overlays: “RIGHT ANGLE”; “90°”
SEQUENCE D — OBTUSE ANGLE
Visual: Show accurate examples 100°, 120° and 150°, all larger than 90° but smaller than 180°.
Narration: “An obtuse angle is greater than 90 degrees and less than 180 degrees. It is wider than a right angle but smaller than a straight angle.”
Exact overlays: “OBTUSE ANGLE”; “90° < angle < 180°”; “100° • 120° • 150°”
SEQUENCE E — STRAIGHT ANGLE
Visual: Rotate one arm until both arms form a straight line. Show horizontal, vertical and diagonal versions, each exactly 180°.
Narration: “A straight angle measures exactly 180 degrees. The line can point in different directions and still be a straight angle.”
Exact overlays: “STRAIGHT ANGLE”; “180°”
SEQUENCE F — REFLEX ANGLE
Visual: Continue rotating beyond 180°. Show accurate reflex angles of 210°, 240° and 300°. Draw the larger-region arc clearly around the vertex.
Narration: “A reflex angle is greater than 180 degrees and less than 360 degrees. Look carefully at the curved marking. It shows the larger angle we are measuring.”
Exact overlays: “REFLEX ANGLE”; “180° < angle < 360°”; “210° • 240° • 300°”
SEQUENCE G — SAME ARMS, TWO POSSIBLE ANGLES
Visual: Keep two rays fixed. Highlight the smaller region as 60°, then highlight the larger region as 300°. Do not move the rays between these two demonstrations.
Narration: “The same two arms can describe two different angles. The smaller region is 60 degrees. The larger region is 300 degrees. The curved marking tells us which region is intended.”
Exact overlays: “60° — SMALLER ANGLE”; “300° — REFLEX ANGLE”
SEQUENCE H — FIVE-TYPE SUMMARY
Reveal the rules one row at a time, then show the complete chart:
“0° < angle < 90° → ACUTE”
“90° → RIGHT”
“90° < angle < 180° → OBTUSE”
“180° → STRAIGHT”
“180° < angle < 360° → REFLEX”
Narration: “Compare an angle’s measure with 90 degrees and 180 degrees. Remember that a full turn is 360 degrees, so a reflex angle is greater than 180 degrees but less than 360 degrees.”
SEQUENCE I — QUICK CHECK
Show one card at a time. Pause before each answer appears:
“40°” → “ACUTE”
“90°” → “RIGHT”
“125°” → “OBTUSE”
“180°” → “STRAIGHT”
“250°” → “REFLEX”
Narration: “Try each one before the answer appears. Which type matches 40 degrees? Now check. What about 90 degrees? Keep going.”
After the reveals: “Excellent. The measure tells us the angle type.”
SEQUENCE J — RECAP AND BRIDGE
Visual: Mili stands beside the completed five-row chart.
Narration: “Do not classify an angle by its direction alone. Compare its measure with the key values, then classify it.”
Exact overlay: “MEASURE → COMPARE → CLASSIFY”
Final overlay: “NEXT: MILI’S ANGLE MISSION — MEASURE, CLASSIFY & REASON”
STRICT ACCURACY
All angle drawings must match the exact labels. A 300° reflex angle must show the large arc; the 60° smaller angle must be separately highlighted. Do not add unsupported classifications, extra characters or extra dialogue. Keep text readable on a mobile screen.
