I listed a bunch of ideas off for my son to pick from with Halloween type themes and black cats was what he wanted to do today so black cats it is.
We found a cat printable pack and my son traced the numbers on this page.Making Learning Fun has a lot of pet activities. This was a fun one rhyming -at words. My son came up with most of these on his own.
The Home Teacher has a great selection of Black Cat activities as well.
