# Lesson Plan

## How Many Months?

Main Subject Area: Mathematics

Duration of Lesson:  30 minutes

Keywords:

• Problem Solving

Brief Description:

Students learn about the first Peter the Mint Eagle, who lived at the Philadelphia Mint from 1830 to 1836. They then determine how many months Peter was there and use pictures, numbers, equations, and/or words to explain how they came up with the answer.

National Standard(s):

• Whole Number Computation

Additional Subject Area Standard(s):

Objectives:

Students will construct number meanings through real-world experiences and the use of physical materials; understand our numeration system by relating counting, grouping, and place value concepts; interpret the multiple uses of numbers encountered in the real world; model, explain, and develop reasonable proficiency with basic facts and algorithms; use a variety of mental computation and estimation techniques; use calculators in appropriate computational situations; and select and use computation techniques appropriate to specific problems and determine whether the results are reasonable.

Materials (online):

Internet access

The H.I.P. Pocket Change(TM) "Meet the Pals" page (Peter)- http://www.usmint.gov/kids/index.cfm?FileContents=/kids/campcoin/pals.cfm

Materials (offline):

Paper

Pencils

Manipulatives, as needed

Coins Used in Lesson:

No specific coins are needed for this lesson.

Grade Level(s):   K-2     3-5

Procedures (online):

1. Have students find the story of the first Peter the Mint Eagle on the H.I.P. Pocket Change(TM) Web site. If needed, guide them to the "Meet My Ancestor" pop-up link on the "Meet the Pals" page that features Peter (http://www.usmint.gov/kids/index.cfm?FileContents=/kids/campcoin/pals.cfm). You may want to have students print the page for later reference.

Procedures (offline):

1. Tell students the story of the first Peter the Mint Eagle.

2. Ask students to determine just how many months Peter lived at the Mint. Have them explain their strategy for solving the problem using pictures, numbers, equations, and/or words.

Assessment / Evaluation:

Were the students able to determine how many months Peter lived at the Philadelphia Mint? How successfully were they able to explain their problem-solving strategies?

Differentiated Learning Options:

With older or more advanced students, you could ask them to calculate how many nights and how many weeks Peter spent at the Mint.

Students in the Philadelphia area could tour the Mint facility and see Peter in his acrylic case.
