Are you looking for a way to teach your students to add that makes it easy and quick? It is very similar to an abacus.
The use of the slash crutch is what makes this algorithm quick and easy. Students are working single digit computations - and have no need to hold or add large numbers mentally or to write out separate equations. Because of this they are less prone to errors or confusion, and more likely to excel at multi digit addition.
The superiority of the efficient algorithm becomes most apparent
when students have larger stacks of multi digit numbers.
