Integers and Negative Numbers
Year 5 students explore integers by extending the number line below zero to understand negative numbers in real-world contexts such as temperature and debt.
What You Need to Know
Key Concept Diagram
Integers include all whole numbers, both positive, negative, and zero
Negative numbers sit to the left of zero on the number line
Comparing integers: −3 is less than −1 because it is further left on the number line
Real-world contexts for negative numbers include temperature below 0 °C, floors below ground, and money owed
