How to Create Shadow Matching Worksheets Step by Step

1

Set Your Page Layout

Open the Page Setup panel and choose a page size: Letter Portrait, Letter Landscape, A4 Portrait, A4 Landscape, Square (1200×1200), or any custom dimension. Pick a page color using the color picker as a fallback background. Select a background theme and adjust its opacity (0–1 in 0.05 steps), then choose a border theme with its own independent opacity control. These layout choices frame your shadow matching worksheet before you configure any content.
2

Choose Exercise Mode and Configure Options

Open the Exercise Configuration panel and select your mode: Shadow Match or Make It Whole. Shadow Match generates black silhouettes from your selected images using pixel-level processing. Make It Whole splits images into halves — choose horizontal (top/bottom) or vertical (left/right) cut direction using the radio buttons that appear in this mode. Toggle the "Show Labels" checkbox (default ON) to display A/B/C/D and 1/2/3/4 identifiers on the worksheet. Toggle "Include Name/Date Fields" to add name and date lines.
3

Select 4 Images from the Library

Open the Image Library panel and browse 104 themed collections with 3,100+ colorful illustrations — animals, food, vehicles, nature, holidays, and dozens more. Filter by theme using the dropdown or search by keyword with 300ms debounce. Click images to select them — the counter shows your progress toward the required 4 images. A selected images preview confirms your choices before generating. You can also upload custom PNG, JPG, or GIF images using the Upload Custom Images panel.
4

Generate the Shadow Match Worksheet

Click Generate to create the matching worksheet. In Shadow Match mode, the app processes each image at the pixel level — loading it to a canvas, extracting pixel data via getImageData, and converting every pixel with alpha > 10 to pure black (R=0, G=0, B=0, A=255) to produce accurate silhouettes. In Make It Whole mode, images are split along the chosen cut direction. Both modes apply Fisher-Yates derangement to guarantee no item appears in its original position. A styled header appears with an amber background (#FFC107), white pill container, and 3px amber border displaying "Shadow Match" and instructions in the selected language.
5

Generate the Answer Key and Download

Switch to the Answer Key tab to see the auto-generated answer key. In Shadow Match mode, each cell shows the original image alongside its silhouette with a label like "A → 2" indicating the correct match. In Make It Whole mode, each cell shows the complete original image with its match label. Download both versions using four dedicated buttons: Worksheet JPEG, Answer Key JPEG, Worksheet PDF, and Answer Key PDF at 300 DPI. Toggle grayscale for ink-friendly versions. Every export is production-ready for Etsy listings, Amazon KDP interiors, and Gumroad product files.

Why Shadow Matching Is an Underserved Preschool Niche

Auto-Generated Silhouettes via Pixel-Level Image Processing

Shadow Match mode creates black silhouettes through real pixel-level manipulation — not CSS filters or pre-made assets. The app loads each image onto a canvas, extracts pixel data using getImageData, and converts every pixel with an alpha value greater than 10 to pure black (R=0, G=0, B=0, A=255). This preserves the exact transparency profile of each image, producing accurate silhouette outlines that reflect fine details like animal ears, vehicle shapes, and object contours. CORS handling ensures cross-origin images process correctly, with a fallback to a solid black rectangle if the canvas is tainted.

Two Exercise Modes: Shadow Match and Make It Whole with Cut Direction Options

One generator delivers two distinct visual matching activities. Shadow Match mode places 4 colored images in the top row and 4 auto-generated silhouettes in the bottom row — solvers identify each image by its outline shape alone. Make It Whole mode splits 4 images into halves and presents first halves and second halves separately — solvers reconnect the pieces to complete each picture. In Make It Whole mode, choose horizontal cut direction (top/bottom halves) or vertical cut direction (left/right halves). The layout adapts automatically: landscape pages use 2 rows × 4 items, portrait pages use 2 columns × 4 items.

Derangement Algorithm Ensuring No Trivial Matches

Both exercise modes use a Fisher-Yates derangement algorithm that guarantees no item appears in its original position. In Shadow Match mode, no silhouette sits directly below its matching image. In Make It Whole mode, no second half appears adjacent to its matching first half. This eliminates the possibility of guessing correctly by position alone and ensures every worksheet presents a genuine matching challenge. The derangement recalculates on every generation, producing different arrangements from the same image set.

Auto-Generated Answer Key with Letter-to-Number Match Labels

Every shadow match worksheet automatically generates a companion answer key on a separate canvas tab. The answer key uses a grid layout where each cell displays the original image alongside its silhouette or complete image, labeled with the correct match like "A → 2". The grid uses 4 columns with 50px gap before the second row and 15px vertical spacing between elements. No manual answer key creation — the answer key stays synchronized with the worksheet. Download it separately as answer_key.jpeg or answer_key.pdf alongside the puzzle worksheet.

Image Library with 104 Themed Collections and 3,100+ Illustrations

Browse 104 themed image collections covering animals, food, vehicles, nature, professions, holidays, sports, seasons, and dozens more. Each theme provides colorful illustrations that produce distinctive silhouettes with recognizable outlines — animal shapes, vehicle profiles, and object contours that challenge visual perception. Filter by theme using the dropdown or search for specific images by keyword. The Commercial tier includes 10 colorful themes for getting started; Full Access unlocks all 104 themes for maximum creative variety across both exercise modes.

Optional Labels and Name/Date Fields

Toggle the "Show Labels" checkbox (default ON) to display A, B, C, D identifiers on images or first halves and 1, 2, 3, 4 identifiers on silhouettes or second halves. When labels are hidden, the worksheet becomes a pure visual matching challenge without letter-number scaffolding — ideal for advanced activities or puzzle books where written answers aren't needed. The "Include Name/Date Fields" checkbox adds name and date lines at the bottom of the page for a polished, professional layout.

Print-Ready PDF and JPEG Export at 300 DPI with Grayscale Toggle

Download shadow match worksheets and answer keys as high-resolution JPEG images or print-ready PDF documents rendered at 300 DPI (6× multiplier, JPEG quality 1.0). Four dedicated download buttons export worksheet and answer key files separately. Page sizes include Letter Portrait, Letter Landscape, A4 Portrait, A4 Landscape, Square (1200×1200), and fully custom dimensions. PDF orientation is automatically detected. Toggle grayscale for ink-friendly versions. Every export is production-ready for digital downloads, printed workbooks, and bulk printing.

Full Canvas Editing with Text Tools, Alignment, and Layering Controls

The Fabric.js canvas provides complete control over every element on your shadow match worksheet. Drag, resize, rotate, and reposition images, text, and generated content freely. Layer controls manage stacking order — bring elements forward or send them back. Lock finished elements while you edit others. Add custom text with seven font options (Lexend Deca, Baloo 2, Nunito, Quicksand, Fredoka, Arial, Verdana), adjustable size and color, and text outline width from 0 to 10 with 0.5-step granularity. Six alignment options plus center-on-page keep layouts precise. Zoom from 25% to 300% for detail work. Undo and redo with unbounded history using Ctrl+Z and Ctrl+Y.
