Make sure you have first read:
If you are just having someone read for 60 seconds and then stopping them and counting how many words they read, this isn't an issue. But if you, like me, want to have a child read the entire passage or maybe see how she does over, say, 5 minutes, here's how to calculate words per minute:
WORDS divided by SECONDS.
You'll get an answer ranging anywhere from .17 to 2.5 - what is this number? This is words per second.
You can then take that number and compare it with the following chart:
Someone whose number was .42 (this is words per second) is reading at a 25 words per minute level. Someone whose number is 1.00 is reading at a 60 words a minute level.
Remember to subtract the missed words from the word total before you do the calculation. If a child reads 54 words in 68 seconds but had 6 mistakes, her number is .70 (48/68, around 43 WPM), not .79 (54/68, 50 WPM.)
