Two of a Kind

Students have been working on multiplying 2-digit by 2-digit numbers.  They have used many of the strategies we have practiced to help them find the products.  One key strategy we practiced is breaking the number apart into smaller numbers. 

The Problem: A theater has 14 rows of seats with 23 seats in each row.  How many total seats are in the theater?

We used an array first to show our problem and then we broke the array into smaller arrays to find partial products.  The students did really well! Below are two examples of this practice.
