Odd and Even Numbers
Year 1 Mathematics NSW Curriculum 30 minutes
WALT - We Are Learning To
Understand what odd and even numbers are Sort numbers into odd and even groups Use objects to show odd and even numbers Explain our thinking to friends and teachers
What Are Odd and Even Numbers?
Even numbers can be grouped in pairs with none left over Odd numbers have one left over when grouped in pairs Example: 4 dots can make 2 pairs (even) Example: 5 dots make 2 pairs with 1 left over (odd)
Hands-On Pairing Activity
Work in pairs or small groups Use 20 objects (counters, buttons, blocks) Group objects into pairs Test if numbers are odd or even Use number cards 1-20 to sort into piles
Let's Discuss Our Findings
What patterns did you notice? How can you tell if a number is odd or even? Which numbers from 1-10 are even? Which numbers from 1-10 are odd?
Reflection Activity
Choose 3 numbers from 1-20 Draw pairs of dots for each number Show if your numbers are odd or even Share your drawings with a partner Explain your thinking
Success Criteria - Can You Do This?
I can explain what makes a number odd or even I can sort numbers into odd and even groups I can represent odd and even numbers using objects I can explain my thinking to my teacher and friends
Supporting All Learners
Extra support: Start with numbers 1-10 and use buddy system Visual aids: Pictures of pairs help understanding Challenge: Explore odd and even numbers up to 50 Extension: Connect to skip counting by 2s
