By default Cisco routers will load balance using static routes. It may be session based or packet based or flow based, but it should balance with the above settings.

A "show Interface summary" should show traffic per interface.

Here's a snippet from a router that's currently in production that has 3 T1s with 3 default routes on one side and 3 sets of routes on the other.
