🎯 Core Features
-
Equation Display: Dynamically updates
multiplier × 3 = product, making each step clear and intentional. -
“Dino‑group” Visualization: Each group of 3 is represented by 3 dinosaur emojis in a dashed box — visually emphasizing the grouping pattern.
-
Counter Controls:
-
Next: increment the multiplier, showing the next multiple up to ×20.
-
Reset: start over at zero.
-
-
Audio-Synced Multiples: Optionally play a song; the script listens to timestamps and auto-advances the multiplication based on predefined sync points — combining music and maths in real time.
-
Timer Display: Shows elapsed playback time, reinforcing the connection between time and sequence.
-
Responsive Design: Resizes beautifully — from mobile to large displays.
-
Visual Cues: “Song is playing…” glows, signaling active playback with motion.

🧠 Why It Works
-
Cognitive Load Reduction
Visual groups and clear equations cut through tension: skip-counting feels natural — even playful. -
Multisensory Reinforcement
Seeing (emojis), hearing (song), and doing (clicking) combine for deeper retention. -
Self‑paced & Autonomy
Learners click or watch along. Supplementing with a song adds an element of performance and anticipation. -
Scaffolded Learning
The code supports up to ×20 — giving structure and boundaries to practice.
🧩 How It Fits in Classrooms
| Mode | Description |
|---|---|
| Demonstration | Teacher projects the interface, pushes “Next” to spark conversation: “What’s 4×3? 5×3?” |
| Individual Practice | Students work independently with headphones, experimenting and checking progress. |
| Music Integration | Pair with a 36‑second song that cues multiples from 1×3 up to 12×3 — ideal for primary-level rhythm lessons. |
🔧 Behind the Scenes (Code Highlights)
-
Uses flexbox for layout and
.containerfills the viewport. -
The
syncPointsarray maps audio timestamps to multiplier values. -
On playback,
timeupdatedetects when toupdateDisplay(), auto-advancing scaffolded visuals in time. -
Taps into CSS transitions and animations like
pulse-glowandgrow-infor visual feedback. -
A clean separation between controls, display, and logic makes it easy to adapt: change the multiplier, replace emojis, or update the sync map.
📌 Extensions & Customizations
-
Parameterize the Multiple
Instead of just 3, allow students to pick any integer (e.g., 4, 7). ChangecurrentMultipleaccordingly. -
Emoji Libraries
Use themed icons — stars, counters, animals — to match different grade levels or content (e.g., 4 groups of 5 coral for 4×5). -
Flexible Sync Maps
Create alternate sync maps for different songs or adjust timestamps to make songs align with visual progression. -
Max‑Multiplier Slider
Let students set a max value (e.g., up to ×10, ×15, etc.). -
Accessibility Tweaks
Add alt-text, ARIA roles, and make the play/pause keyboard-navigable.
✅ Final Thoughts
This mash‑up exemplifies how simple code can’t just explain math — it celebrates it. Learners see the why behind skip counting. They feel the rhythm of repetition. And with a few smart updates, this becomes a toolkit for any multiple, any theme, any grade.
