Teacher Script: "Let's look at another way to express multiplication. When we say 'Ten multiples of nineteen,' we're talking about multiplication. The phrase 'multiples of' tells us we're multiplying. So 'Ten multiples of nineteen' becomes 19 * 10 in math language. Notice how the order of the numbers changes in the math expression. Can you think of other situations where you might use 'multiples of' to describe multiplication? How would you write those as math expressions?"
