**Middle School Maths Challenge**

**Rates, averages and crazy drummers (That’s all of them, man!)**

Here are 3 classic rock songs. Listen to the tracks and find the beat per minute or bpm of each song.

HINT: Count the beats and ask a friend to time you.

# Beat 1: AC/DC … T.N.T.

………………………………………………………………..

# Beat 2: Queen … Another one bites the dust

# BIG challenge 1:

Drummer: Ramon Sampson

Pick one beat and see if you match the exact bpm. If you don’t have drumsticks use pencils.

HINT: Count the beats and ask a friend to time you.

# BIG challenge 2:

Record yourself drumming to your own natural beat for 10 seconds.

Listen to your recording and count the beats. Multiply by 6 and you have your bpm.

Do this 4 times.

Calculate your **average** bpm.

Then for each of the 4 trials calculate the % error.

Pro drummers do not like to be out by 1 beat or 1 bpm. They want to hit ZERO % error. I beat out per minute for a bpm = 84 would mean an error of approx 1%.
