This is the problem with relying on secondary sources, including press releases written by IRS flacks who must stay around during the holidays because they don't have the seniority to take "use or lose" leave.  I suggest you rely on primary sources, like the law itself.  It's not that difficult to download, and much of it is written in language that a high school student can understand.

‘‘(1) $600 ( $1,200 in the case of eligible individuals filing a joint return), plus
‘‘(2) an amount equal to the product of $600 multiplied by the number of qualifying children (within the meaning of section 24(c)) of the taxpayer.
