Real-life examples help 7th graders understand variables and constants in math.

Let’s take a car's speed as an example.

Here, the variable $s$ stands for speed.

On the other hand, the constant $60$ could be the speed limit.

When you want to find out how far the car travels, you use the formula $d = s \cdot t$.

In this formula, $t$ stands for time, which is another variable.

By seeing how these parts work together in real life, students can build a strong foundation in algebra.
