Supporting grades: 5

Description: A short lesson showing two approaches to finding 2/3 × 6: making 6 copies of 2/3, or making jumps on a number line diagram. Let's think a little bit about what it means to multiply 2/3 times 6. One way to think about it is to literally take six 2/3 and add them together. And if we wanted to actually compute this, we're going to take these six 2's and add them together.
