Students skip count by fives after trading pennies for nickels. They group pennies by five and count on to then find the value of a set of coins.

Content in this Lesson

  • Grouping and counting objects by fives and tens [E1].
  • Skip counting by five to find the value of a set of coins [E2].
  • Reading and writing numbers to 50 [E3].
  • Representing and identifying numbers using coins and ten frames [E4].
  • Connecting representations of quantities
    (e.g., coins, ten frames, counters) [E5].
  • Connecting the value of a nickel to the quantity of pennies.
  • Choosing good tools and an efficient strategy to count [MPE2].

Materials Preparation

Prepare Construction Paper. Each student will need a 6-inch by 18-inch sheet of construction paper. Cut several 12-inch by 18-inch sheets in half along the long edge.

Prepare to Display Hand Tracings. In the lesson, students will display their hand tracings side by side. Identify a space that is large enough and easily seen to display these.

Highlight Fives and Tens on Classroom Number Line. Highlight multiples of five and ten on the classroom number line. Use two different colors of self-adhesive notes. Place one color above the multiples of five and the other color above the multiples of ten. Multiples of 5 will have two adhesive notes: one for 5 and one for 10, since they are multiples of both 5 and 10. Leave the adhesive notes on the classroom number line for use in later units.

Prepare Bags of Pennies. Prepare plastic bags of 35–50 pennies each, one bag per student pair. Vary the number of pennies in each bag. Try not to have multiples of five.
