Steps:
1. Circle the greater factor.
2. Write the greater factor in expanded
form and draw the area model
proportionally.
3. Write the lesser factor in expanded
form on the outer left side of the
area model.
4. Write each equation in the
corresponding place value section
and find the product for each.
5. Add the products to solve.
