In Lesson 3, students solved problems using nickels and dimes. Since two nickels can be traded for a dime, you need twice the number of nickels as dimes to have the same value. You may demonstrate this trading on the overhead with nickels and dimes.

  1. 4 dimes
  2. 8 nickels
  3. 7 dimes
  4. 14 nickels
  1. Answers will vary. Possible response: I skip count more times using nickels than I do dimes. 5 is less than 10 so you need more 5s than 10s to make 100. You need more nickels than dimes to make 100¢.

Ongoing Assessment

Use DPP item P to assess students' abilities to use skip counting to find the value of a collection of coins [E6] and to recognize the relationship between larger and smaller units of measure (1 dime is 2 nickels) [E8].
