  1. 2.7 Multiplying Whole Numbers (With Renaming): Using Area Models

  2. Review • Solve using standard algorithm and an area model • 73 x 64 • 648 x 35 • 48 x 35

  3. Objective • SWBAT find partial products by: • Using standard algorithm with renaming • Using the distributive property • Using area diagrams.

  4. Problem A • The length of a school bus is 12.6 meters. If 9 school buses park end to end with 2 meters between each one, what’s the total length from the front of the first bus to the end of the last bus?

  5. Problem 1 • Solve first by using an area diagram/model. Then solve using standard algorithm. • 524 x 136

  6. Problem 2 • Solve first by using an area diagram/model. Then solve using standard algorithm. • 4,519 x 326

  7. Problems 3-4 • Partner A, use the standard algorithm to solve. Partner B, draw an area model to solve. • 321x 326 • Repeat for the second problem with partners switching roles. • 509 x 306

  8. Exit Ticket • Draw an area model, and then solve using the standard algorithm. • a. 642 × 257 = ____ 6 4 2 • × 2 5 • b. 642 × 207 = ____ 6 4 2 • × 2 0 7
