Yay. This is a grade 3 Common Core strategy. Now use that same area model to visualize division. The number in the “box” is the area. And the divisor is one of the side lengths and the quotient is the other.

Thanks @howie_hua I remember when I was first shown this approach (as an adult…) which helped me expand the process of “why” within multiplication a bit better than “number of apples on trees in an orchard” I usually used as a metaphor

If you can do it I highly recommend watching 1 shining moment live when your team cuts down the nets. Hits totally different.

[Q]: Why doesn't Europe go to [President] Trump and say, "If you want assistance in the Gulf, here's what we want you to do on Ukraine"? President Stubb: I think it's a really good idea. I think it's actually a really good idea. I'll think about it.

The Drama is now available on streaming and I highly recommend you give it a shot if you haven’t seen it in theaters. Robert Pattinson & Zendaya really impressed me & the story itself is strong. There’s something endearing about this film that I think will give it lasting power.

Robert John Carr is an Australian retired politician. This is what he said recently, what do you think about this? Do you agree with him or not? If you do, why? If you don't, why not?

I'm shook that people actually think this way. "Why don't you ask the Andersons if you can borrow their electricity? Um, because I know you're not home, and um, you can't do anything about it technically." What would you do if this was your home?

If you are a sane person who enjoys living in the western world and you appreciate America and it’s freedoms I really recommend you listen to this video in it’s entirety and then I really recommend that you think about it and figure out why this is happening and what you plan on doing to stop it because it is so much deeper than any one country.
