### Integer subtraction

I recently finished another video of mine, this time on the topic of subtraction of integers. You can watch it here:

In it, I explain three different models that we can use to justify the rules for subtracting integers to the students. The three models are:

1) number line jumps;

2) concept of difference;

3) counters.

Please read about these models in more detail in my updated article How to teach operations with integers.
