## Summary

Students will play a coin identification game to familiarize themselves with coin values. They will add coin values to determine the game's winner.

## Objectives

- Students will compare numbers between 1 and 100 using manipulatives.
- Students will recognize and express the value using cent notation of penny, nickel, dime, and quarter.
- Students will add coin amounts together.

## Subject Area

- Math

## Grades

- K
- 1st
- 2nd

## Class Time

- Total Time: 0-45 minutes

## Materials

For each team you need:

- 1 small tackle box or similar sectioned, covered box with labels in each section reading 1, 5, 10, and 25 cents
- Separate (sectioned) containers of coins for the “bank” (one container for each team of 2 or 3 players)
- A handful of play coins of each denomination (1, 5, 10, and 25 cents) for each “bank”
- Counters (such as marbles, small building blocks)
- Math journals

## Lesson Steps

- Introduce this activity to the students by reviewing the coin amounts of 25 cents, 10 cents, 5 cents, and 1 cent. Tell the students they will be working in teams and playing a game together.
- Explain the following rules to the students: A player puts a counter into the box and shakes the box so that the counter lands in one of the coin slots. The player opens the box and reads the amount on the slot aloud. The player then takes a coin or coins equal to that amount from the bank and adds it to his pile. Play rotates clockwise and continues for four turns. Then the players count the total amount of their coins. The player who has the greatest amount wins.
- Divide the class into teams of two to three players and distribute the materials to each team.
- The students can play the game several times. At the end of each game, the students can record their total amounts in their math journals.

## Differentiated Learning Options

For more advanced students, label the tackle box with amounts that require the students to assemble different coin combinations.

## Assess

- Evaluate the day's math journal entries.
- Observe students when they are adding their money together.

## Common Core Standards
