Animation Specification for Grade‑3 UK Place‑Value Lesson (Elimination Method)

Goal: Introduce and reinforce the concept of place value for three‑digit numbers using the elimination method (isolating each digit by “eliminating” the others). The video is aimed at UK Year 3 pupils, so the language and pacing are child‑friendly.
Style: Bright, colourful, cartoon‑like visuals with smooth, playful transitions. No heavy text; information is conveyed through numbers, colour‑coded blocks, and simple on‑screen labels with opaque backgrounds when needed.
Duration: ~25 seconds (well under the 30‑second limit).

Core formula (shown as a block):
$\text{ABC} = A\times100 + B\times10 + C\times1$
Elimination steps (illustrated visually):
1. Original number – e.g., $342$ .
2. Hundreds elimination: Replace tens and ones with zeros → $300$ . Show that $300 = 3\times100$ .
3. Tens elimination: Replace hundreds and ones with zeros → $40$ . Show that $40 = 4\times10$ .
4. Ones elimination: Replace hundreds and tens with zeros → $2$ . Show that $2 = 2\times1$ .
Final recombination (brief flash): $300 + 40 + 2 = 342$ .

Element	Description	Colours / Styling
Background	Light pastel gradient (soft blue to light pink) to keep focus on foreground.	—
Number Tiles	Large, bold digits (e.g., "3", "4", "2") on separate rectangular tiles. Each tile has a thick, rounded border.	Hundreds tile – royal blue, Tens tile – emerald green, Ones tile – sunset orange.
Place‑Value Blocks	Three stacked block groups representing 100‑s, 10‑s, 1‑s. Each block is a 3‑D‑style cuboid with a subtle shadow.	Same colour scheme as tiles; each block labelled with a small opaque label (e.g., "100", "10", "1") in white text on a dark semi‑transparent background.
Elimination Highlight	When a digit is being isolated, the other two tiles fade to 30 % opacity and a bright halo (yellow) surrounds the active tile.	Halo – bright yellow; faded tiles – low opacity.
Animated Arrows	Curved arrows that move from the active tile to the corresponding place‑value block, indicating the multiplication (e.g., "3 → 300").	Arrow colour matches the active tile; arrowheads are cartoon‑style.
Number Line (optional)	A short horizontal line appears during the final recombination to show addition of 300, 40, and 2.	Light grey line with colourful markers for each term.
Labels	Minimal on‑screen text such as "Hundreds", "Tens", "Ones" appears only when a step begins, inside a rounded rectangle with an opaque background (white text on dark navy).	Background: dark navy; text: white.

Time (s)	Segment	Details
0‑2	Intro – Fade‑in background, then the full number "342" appears centered, each digit on its coloured tile.
2‑5	Hundreds elimination – Tens and ones tiles fade, halo around "3". Arrow from "3" to a stack of three hundred‑blocks (each block labelled "100"). Blocks appear with a pop‑up bounce. Fade‑in label "3×100 = 300" (opaque background).
5‑7	Hold for comprehension, then all tiles return to full opacity.
7‑10	Tens elimination – Similar process for "4" (green). Arrow to four ten‑blocks, label "4×10 = 40".
10‑12	Hold, then reset opacity.
12‑15	Ones elimination – Highlight "2" (orange). Arrow to two single‑unit blocks, label "2×1 = 2".
15‑17	Hold, then all three results (300, 40, 2) slide down to a short number line.
17‑20	Recombination – Numbers on the line merge with a gentle sparkle effect, forming "342" again. Brief flash of the formula $300 + 40 + 2 = 342$ .
20‑22	Summary label – "Place‑value using elimination method" appears with opaque background.
22‑25	Fade‑out to black.

Static camera throughout; slight zoom‑in (1.2×) when a tile is highlighted to draw attention, then zoom back to original framing after the step.
Pan is not required; all elements fit comfortably in a 16:9 frame.

Sound‑free (as per constraints). All emphasis is visual.
No extra text beyond the minimal labels described; each label uses an opaque rounded rectangle for readability.
Consistency: All colours, fonts (simple sans‑serif), and animation easings (ease‑out bounce for block appearance, linear for arrows) remain consistent across steps.
Scene constraint: The entire sequence fits within a single Manim Scene class.
