Changing "Our Products" in each screen to the category name

I hope this hasn't come up yet as I searched and couldn't find anything.

I am using the gridmarket child-theme to build a website and wondered how easy it would be to display the name of the category at the top of each page instead of each category page displaying "Our Products." It seems like a pretty simple task as just about every other page/post in Wordpress works this way, but I am fairly new to the whole php/css thing.

Thanks in advance for your help.
