Power to speaker

I have a student wanting to measure the power input to a speaker. We have
an oscilloscope ( old, single trace, but could get a better one). We can
see the input voltage and the speaker is rated to be 4 -6 Ohms. I regret
that I cannot think of how to measure the power input from what we have.

Any guidance would be appreciated.
