If you can visualize, try that.

Imagine a stack of a stack of 5 pennies and a stack of 4 pennies. Pile them into 1 stack and how many?
If you're a good visualizer you may wanna learn the abacus. Once you learn it, you can visualize an abacus and do math that way. It's quite common and is the reason why some countries still teach with this tool, but it relies entirely on visualization processing so it's not for everyone.
