Volunteer Work near Chicago?:'/

Hi so I live near Chicago Ilinois and I'm looking for a place that I cab volunteer at that helps kids one-on-one not the whole raise money stuff, and I'd like to work with younger kids, but everything says you have to be 18 or with an adult but I'm 14 and my parents don't want to help out so won't do it (and I know no one else except kids my age, who'd volunteer) so I was wondering if anyone knew of any good places or websites I could check out? Thanks!!:)
Btw I've already searched through some of the things off of Volunteermatch.com so please don't just restate for my to check that site again.
