Reading thermometer scales that extend below zero, correctly identifying negative temperature values, and ordering temperatures from coldest to warmest including negatives.
Where your child meets this in real life: Reading freezer thermometers, weather reports during cold spells, comparing winter temperatures across cities
SEAGReady breaks read and order negative temperatures into 3 steps, taught in order so each skill builds on the last.
Read thermometer scales that show negative temperatures, counting down from zero
Order a set of negative temperatures from coldest to warmest
Order temperatures that include both positive and negative values
Three free sample questions from our read and order negative temperatures course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Sean checks the outdoor thermometer on a cold February morning. The scale is marked in 2s and the liquid is 2 marks below zero. What temperature does the thermometer show?
Answer: A. -4°C
The scale is marked in 2s, so each mark represents 2 degrees. 2 marks below zero = 2 x 2 = 4 degrees below zero. The temperature is -4°C.
Stuck? Start here: The thermometer is below zero, so the temperature will be negative.
Niamh compares the temperatures in three freezers: -6°C, -2°C, and -10°C. Which order shows these temperatures from coldest to warmest?
Answer: A. -10°C, -6°C, -2°C
With negative temperatures, further from zero = colder. -10°C is furthest from zero (coldest). -6°C is in the middle. -2°C is closest to zero (warmest). Order: -10°C, -6°C, -2°C.
Stuck? Start here: Remember: with negative numbers, the bigger the digit, the colder the temperature.
Aoife records temperatures in three European cities: London 3°C, Moscow -8°C, Paris 1°C. Which order shows these from coldest to warmest?
Answer: A. -8°C, 1°C, 3°C
Negative temperatures are always colder than positive ones. -8°C (negative) is coldest. Then 1°C (positive, smaller digit). Then 3°C (positive, larger digit) is warmest. Order: -8°C, 1°C, 3°C.
Stuck? Start here: Remember: all negative temperatures are colder than all positive temperatures.
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Aoife checks the outdoor thermometer on a frosty January morning. The scale is marked in 2s and the liquid is 3 marks below zero.
What temperature does the thermometer show?
0 - (3 x 2)
Step 1 of 4
Aoife checks the outdoor thermometer on a frosty January morning. The scale is marked in 2s and the liquid is 3 marks below zero.
What temperature does the thermometer show?
The thermometer shows -6°C.
The key insight: Below zero, the numbers get more negative as you go further down - just like going deeper into a freezer!
Watch out: Reading -6°C as 6°C. Forgetting the minus sign means you've ignored that the temperature is below freezing.
These are the misconceptions we see most often in read and order negative temperatures, including the ones our practice questions are specifically designed to catch.
Struggling with read and order negative temperatures? 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.
