The Fewest Pieces Rule

The TIMS Candy Company decided that the best way to record the amount of candy it makes is to use the smallest possible number of base-ten pieces. The company calls this the Fewest Pieces Rule. For example, the best way to record 32 candies is to use 3 skinnies and 2 bits.

The best way to record 457 candies is to use 4 flats, 5 skinnies, and 7 bits.

Writing a number showing partitions using the Fewest Pieces Rule is using expanded form. Expanded form for 457 is 400 + 50 + 7. Standard form is 457. So we write 457 = 400 + 50 + 7.

13. Show each number using base-ten shorthand. Make sure your answer uses the Fewest Pieces Rule. Write a number sentence with expanded form on one side of the equal sign and standard form on the other like the example above.
    1. 236
    2. 507
    3. 5235
    4. 6048

In Questions 14–20:

1. Write a number sentence and tell how many Chocos were made.
2. Then, check if the Fewest Pieces Rule is followed. If it is not, use base-ten shorthand to show the candy using the fewest pieces possible. Write a new number sentence to match.
