This model is a printable deck of numbered cards (0–20) with +, −, and = symbols, designed for Kindergarten through Grade 2 number work and math-based games.

These cards are great for:

• Number recognition and counting
• Simple addition and subtraction
• Games like War, Memory, matching games, and basic math challenges
• Open-ended play—use them for any age-appropriate game you can come up with

Each card is 4 layers thick at 0.08 mm per layer, giving them a very solid feel and making them surprisingly satisfying to shuffle compared to real cards. 

Design Details

• Black card body to prevent numbers from showing through the back
• High-contrast numbers and symbols for easy readability
• Two included color sets:
  • Black & White
  • Black & Purple

Feel Free to customize as you want with your favorite color combo.
