52 legs, there are 16 animals, how many chickens and pigs are there

You can solve this with algebra. The following solution can be done mentally by a 5th grade student.
Start with 16 pigs, that gives 64 lesg.
Each pig changed for a chicken reduces 2 legs, and we need to reduce 6452=12 legs.
So change 6 pigs for chickens to get 10 pigs and 6 chickens.
