Image descriptions and plain text captions of written content are expected of all screenshots. Here are some image text extractors (I looked these up quick and will gladly take FOSS recommendations):

-web

Please begin copied raw text posts (lacking a screenshot that makes it apparent it is from Tumblr) with:

I guess we used it for an exercise or something a couple times, but never for more than indicating how numbers work. They've taken that idea and kind of run with it, instead of leaving it behind once the basics of addition have been mastered. I learned multiplication as just repeated addition, and there's no reason IMO to get a number line involved because addition should already be mastered.

This is a 2nd grade class, and I expect them to have long since mastered addition. At that point, a number line feels like a crutch more than a useful tool. Sure, use them in kindergarten and first grade to grasp how counting works (and counting by 2s and 10s), but that should honestly be as far as it goes. But they still use it for fractions and larger sums and products.
