Do Surviving Children of a Veteran Qualify for Benefits?

Probably not. As an active reserve member, your son probably didn’t have any GI Bill benefits for which he was eligible (except, perhaps, the Montgomery GI Bill – Selected Reserve, if he signed up for it, but that must be used while on active drill status). Even if he was eligible, his benefits would have expired by now, so there are no benefits to pass on. There is also no mechanism for transferring old benefits to dependents.

If your son’s death were service-related, or if he was totally and permanently disabled due to a service-related condition when he died, then his children may have qualified for the Survivors’ and Dependents’ Educational Assistance Program (DEA). They would have to use these benefits, if they qualified, before their 26th birthday.
