Lesson 16

Identify Quarters

Lesson Purpose

The purpose of this lesson is for students to identify quarters and find the total value of a set of coins including quarters.

Lesson Narrative

In a previous lesson, students recognized dimes, nickels, and pennies and learned their values. They used different strategies to find the value of a mixed set of coins.

In this lesson, students recognize the quarter and learn its value. They find the value of groups of coins and look for ways to represent the same value with different coins. Throughout the lesson, students make connections between quarters and combinations of other coins and notice that if they look for ways to use coins with a larger value first, they can be more certain they are using the fewest amount of coins (MP8).

In both activities, students continue to practice finding the values of coin collections using methods for adding within 100. Throughout the lesson, look for the different ways students find the value of coins collections and organize their thinking. While some students will continue to group like coins and add to find the total value, others will count on from the largest value (25, 35, 45, 50, 55, 56, 57, 58) or look for other ways to use ten (25, 30, 40, 50, 55, 56, 57, 58).
