• 3 category label cards
• 2 versions: Color-coded backgrounds and white backgrounds with borders
• 7 PDF pages ready to print on US Letter or A4

💡 Learning Benefits

• Develop visual discrimination by comparing physical attributes
• Practice categorization and sequencing skills
• Build early math concepts through hands-on exploration
• Strengthen focus and concentration with intentional sorting tasks

🎯 How to Use

• Print and laminate cards for durability

🍂 Teaching Tip from a Montessori Guide

Size sorting is a foundational sensorial skill that prepares children for understanding mathematical concepts like greater than, less than, and seriation. Start with just 3-5 objects and gradually add more as confidence builds. Encourage children to verbalize their reasoning: "This tulip is larger than this one because..."
