Understanding that negative numbers represent values below zero, using temperature as the primary context (e.g., -5°C means 5 degrees below freezing).
Where your child meets this in real life: Understanding weather forecasts in winter, freezer temperatures, or reports about cold countries
SEAGReady breaks understand negative numbers into 2 steps, taught in order so each skill builds on the last.

Compare negative numbers correctly, understanding that -10 is less than (colder than) -5
Three free sample questions from our understand negative numbers course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Jamie’s temperature reading is marked on the number line. How many degrees below freezing is it?
Weather stations A and B plot their readings on the number line. Which station had the colder temperature?
Poppy plots three freezer readings on the number line. Which temperature is coldest?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Mei checks a winter weather forecast. The thermometer shows the temperature is −5°C.
How many degrees below freezing is this temperature?
−5°C
Zero degrees (0°C) is the freezing point of water
Step 1 of 4
Mei checks a winter weather forecast. The thermometer shows the temperature is −5°C.
How many degrees below freezing is this temperature?
The temperature is 5 degrees below freezing.
The key insight: The minus sign means 'below zero' - think of going underground!
Common mix-up: Thinking −5°C is warmer than 0°C. Negative means below zero, so −5°C is actually colder than freezing point.
These are the misconceptions we see most often in understand negative numbers, including the ones our practice questions are specifically designed to catch.
Struggling with understand negative numbers? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
