When it comes to fractions, I always think of it in terms of money. Like, how many $0.50 candy bars I can buy for three bucks.

how would you do this with multiple fractions? I like the multiple molders to describe how to do it!

You’re amazing! I’m an English teacher with a different math mind. So every time I answered a math exercise my teacher used to say: “yes, that’s the result, but now do the math the way I taught you.” And here I can see different ways of solving the same thing.

Awesome! Have you made any similar videos about negative numbers? Students have a really hard time understanding how two negatives multiply to become a positive.

Something that's often not pointed out is that the ambiguity of division (dividing by group size, or number of groups?) is a direct consequence of the commutative property of multiplication.

Love this video. It shows how pictorial representation and real life contexts are so important in maths. For concrete learners, you could have them physically scooping half cups of rice etc.

I’m doing this right now with my 6th graders!!! Do you have a video explaining the models when it’s a fraction divided by a whole?
