Meet Alex, the Math Whiz!
March 1, 2012

Alex has been able to add numbers up to 8. He can also add objects from three different groups up to a total of 8. Not even chimpanzees have been able to do this. The researchers at Harvard University are amazed! Way to go, Alex:)

A funny part of this story is that the discovery of Alex being able to add was a surprise! A researcher was working with another parrot, Griffin, to see if he could notice more than one click sound. After two click sounds, Griffin said nothing. The researcher clicked twice more and Alex said, “four.” After two more clicks, Alex said, “six!” That is when the adding experiments began with Alex.

STEM Challenge: Why do you think Alex can only count to 8?
