This really improved my own ability to understand subtracting! Why do the subtraction facts not include 19?
Glad it was helpful, Sarah! Children should definitely be able to quickly calculate 19 -9 or 19-10. It’s a little bit of a technicality, but I consider those mental math/place-value questions rather than subtraction facts. They’re in the same category as problems like 79-9 or 79-10–questions that kids should be able to answer quickly using place-value knowledge, even if they don’t know them by heart.
Happy Math!
