If you have three counters, you can arrange them on a grid to make a rectangle like this:

Are any other rectangles you could make with just three counters?

If you had six counters, you could make a rectangle like this:

Are there any other rectangles that you could make with six counters?

Imagine you have 18 counters to put on a grid.

Arrange any number of counters on the grid to make a rectangle (not just its outline).
How many different rectangles can you make with each number of counters?
