• Framework: Montessori
• Unit: Mathematics
• Learning area: Number Concepts
• Level: Ages 4-6

Objectives

• Distinguish even from odd numbers
• Understand pairing concept
• Classify numbers confidently
• Discover number patterns

Materials

• Counters (chips or beads)
• Number cards 1-10
• Even/odd sorting mat
• Number line

1. Place number card 2. 2. Lay out 2 counters in pairs. All paired—'2 is even.' 3. Place number card 3. 4. Lay out 3 counters in pairs. One left over—'3 is odd.' 5. Continue through 10. 6. Sort number cards into even and odd. 7. Discover the pattern: even, odd, even, odd... 8. Test larger numbers.
