Let’s get the idea.

Here’s how it works

Negative numbers sit to the left of zero on a number line.

What we’re exploring

what negative numbers are
how to count down past zero
how to read freezing cold temperatures

Further left means a smaller number, even below zero.

LET’S WORK ONE OUT TOGETHER

A little example

Which is colder: −3°C or 2°C?

1
Mark −3, 0 and 2 on a number line.
2
−3 is left of 2, so it is smaller.
3
−3°C is colder.

Make a little room for your workings.
