FAQ

What relationship does the word 'so' express in a combined sentence?

'So' signals a result or consequence — the second sentence is what happened because of the first (It was raining, so we stayed inside.).

How does using 'so' to combine sentences build reasoning skills?

Students must understand a cause-and-effect relationship between two ideas before they can use 'so' correctly, connecting grammar to logical thinking.

Is 'so' harder than 'and' for 1st graders to use?

Yes — 'and' simply adds information, while 'so' requires understanding a logical relationship between two events, making it a step up in conceptual difficulty.
