1. On Saturday, 264 people ride a carousel in the park. On Sunday, 3 times as many people ride the carousel. How many people ride the carousel on Sunday?

A. What is the first step for showing the problem in an area model?
The first step for showing the area model is to express  the number in expanded form.
B. Why do you multiply the hundreds first?

Explanation:
I multiplied hundreds first to find the sum of all partial products we need to find the product of big number first.

Write the partial products in each section of the area model.

C. How can you use place value to help you record the partial products and find the whole product?
The place value helps us to multiply with the hundreds, tens and ones separately to find the partial products and the whole product.

D. How many people rode the carousel on Sunday?
792 people rode the carousel on Sunday.

My estimate is 260 x 3 = 780
The product of 264 and 3 is 792
