Greatest Product

Directions:
Partner A chooses a number card and writes the number in one of the blanks for Round 1.
Partner B does the same.
Repeat until each partner has a two-digit by three-digit multiplication problem.
Find the product.
The partner with the greater product wins a point.
The partner with the most points after 5 rounds wins the game.

Desperately Seeking 9 New Units (Optional)

Tyler notices that when he uses the standard algorithm and composes a new unit, sometimes there is 1 new unit, sometimes 2, all the way up to 8. He has not seen an example with 9 of the new unit.

For each of these products, how many of each new unit do you compose?
