Printable Preschool Learning Worksheets

I need a fresh set of classroom-ready worksheets for preschoolers that I can print straight from a PDF. The pack should gently introduce three core concepts: basic counting, alphabet recognition, and identifying shapes and colors.

Here is what I have in mind:
• Visually engaging pages that keep three- to five-year-olds interested without overwhelming them.
• Clear instructions and plenty of white space so teachers or parents can explain each activity easily.
• Consistent style across all pages—same fonts, color palette, and illustration style—so the collection feels like a single unit.
• Print-optimized PDFs (A4 and US Letter) with margins that accommodate home or school printers; no interactive features needed.

Please build each worksheet from original or properly licensed graphics and include a brief answer key where relevant (e.g., counting totals). When the set is complete, send over the finished PDFs plus the editable source files you used (Illustrator, InDesign, or similar) in case I need to tweak wording later on.

If this sounds clear, let me know how many worksheets you think suit these topics and your estimated turnaround time.
