Main teaching video — ONE TomoMotion master prompt TOOL: TOMOMOTION Attach: all four geometry reference images from Section 4. Submit the following as ONE prompt. The internal sequence headings are instructions within the same continuous generation, not separate prompts. COPY INTO TOMOMOTION — ONE MASTER PROMPT Create one continuous, coherent premium educational geometry animation for Grade 6 Mathematics, 16:9 landscape. Topic: “Mili & Tara’s Angle Mission — Turn, Classify & Connect”. This is a problem-solving mission and recap, not a repeat lecture. Use clean vector-style geometry, smooth connected transitions, a light uncluttered background, restrained blue/teal/amber accents, consistent line thickness and large mobile-readable diagrams. Use the attached acute, right, obtuse and straight-angle references only to preserve geometry. Do not generate spoken dialogue, subtitles, labels, captions, logos or written text. The source-script narration and all exact text will be added by the editor. Do not include clip-duration estimates. CONTINUOUS SEQUENCE 1 — MISSION 1: ROTATE Show two rotating-arm models starting from the same initial position, with each pivot fixed. Model A shows a smaller turn; Model B shows a farther turn and a wider opening. Ask visually through the sequence by holding both models still for a learner-thinking pause, then compare the openings. Make clear that a greater amount of turn creates a wider opening. Do not change the pivot position or confuse arm length with angle size. CONTINUOUS SEQUENCE 2 — MISSION 2: MATCH Show one fixed angle-shaped slit/target and three rotating-arm models. A is too narrow, B is too wide, C has exactly the same opening as the target. Show Tara testing A, then B, then C one at a time. Animate C fitting exactly over the target by matching the vertex and aligning one arm, then comparing the other arm. Next, lengthen both arms of the matching pair without changing either arm’s direction or the opening. The angles remain equal. The visual must communicate that opening—not arm length—determines angle size. CONTINUOUS SEQUENCE 3 — MISSION 3: IDENTIFY THE SPECIAL TURN Use one clearly visible fixed pivot and one stationary arm. Rotate the second arm through these exact positions in order: A) Stop before a quarter turn: the opening is smaller than a right angle. This is acute. B) Stop at an exact quarter turn: the arms form a right angle. Add a precise square-corner marker at the vertex. C) Continue beyond a quarter turn but stop before a half turn: the opening is greater than a right angle but smaller than a straight angle. This is obtuse. D) Continue to an exact half turn: the arms point in opposite directions on one straight line. This is straight. For each challenge, show the geometry first, hold a clear thinking pause, and only then move to the next geometry state. Do not generate answer text. Then show all four states together in the order acute, right, obtuse, straight. The right-angle marker must appear only on the right angle. CONTINUOUS SEQUENCE 4 — MISSION 4: REAL-LIFE ANGLE DETECTIVE Show three clean, photorealistic or premium 3D inserts connected to the geometry workspace: 1) Notebook corner: show an open notebook with a clearly visible corner that forms a right angle; highlight the corner without adding text. 2) Scissors: show safe, realistic scissors opening around the fixed central screw. First show a small acute opening, then open them farther so the opening becomes obtuse only after it passes a right angle. Do not imply scissors always make one type of angle. 3) Straight edge: show a ruler edge or two straight arms lying exactly on one straight line, representing a straight angle. Keep each example uncluttered and return smoothly to the main geometry style. CONTINUOUS SEQUENCE 5 — FINAL MIXED CHALLENGE Show four mathematically accurate angles in different orientations and in a deliberately mixed arrangement, not ordered from smallest to largest. Hold the four examples for a learner-thinking pause. Then spotlight each in sequence for the editor to add the answer labels acute, right, obtuse and straight. Rotate the entire set together without changing any angle’s opening. The angle types remain unchanged when orientation changes. CONTINUOUS SEQUENCE 6 — FINAL RECAP Return to the rotating-arm model with Mili and Tara absent from this core animation. Show a visual four-step progression using geometry only: TURN → LOOK AT THE OPENING → COMPARE WITH A RIGHT OR STRAIGHT TURN → CLASSIFY. End on a clean still composition with the four angle types arranged together and a separate comparison pair ready for editor overlays. The final frame must be uncluttered and leave safe space for a transition card. STRICT GEOMETRY AND QUALITY RULES Keep every pivot fixed while an arm rotates. Angle arcs must match the real openings. Do not alter an opening when only arm length or orientation changes. A right angle must be exact and marked with a square. A straight angle must have opposite rays on one straight line. An obtuse angle must be greater than a right angle and less than a straight angle. No degree numbers, no protractor, no measurement demonstration, no reflex angles, no incorrect perpendicular lines, no floating points, no malformed arms, no garbled labels, no watermarks, no decorative particles and no extra characters. Use smooth transitions and pauses; never reveal an answer before the thinking pause. Core animation note for the editor The TomoMotion render is the visual track only. Add the source PDF’s exact teaching dialogue once as one narration track, synchronised to the sequence above. Do not repeat the opening lines or closing lines in this narration. If the master render cannot produce reliable pause timing, hold the relevant still frame in editing before revealing the answer.

Video narration

Does a longer door edge make a bigger angle? At its hinge, the pivot stays fixed as the door swings. Open it farther, and the gap gets wider. But a longer arm does not make a bigger angle. Only the opening changes its size. Compare the door's opening with a right turn, like a notebook corner: smaller is acute; exactly a quarter turn is right. Wider than right, but not straight, is obtuse. A half turn, with arms pointing opposite ways on one line, is straight. Scissors can move from a small opening to a wider one, so judge how far they open. Now sort four angles, even when they face different directions: their type stays the same when you turn them. No-the door's angle depends on how far it opens, not how long its edge is. Compare its opening with a right or straight turn.
