# Coin Bubble: A Game’s Worth of Practice

Knowledge Constructor and Computational Thinker

### Overview​

In this online game, Coin Bubble by Greg Tang Math, students make a given monetary figure using a ten frame of coins. Students work with higher value denominations as the game progresses. In addition, students can use exchanges to get to their figure faster.

Students will:

• Be able to make a given monetary amount using coins and/or bills for numbers less than \$20.

• Be able to use monetary exchanges for both coins and bills to create monetary amounts faster.

Vocabulary Words:

1. Monetary Exchange: A monetary exchange is the use of a different combination of coins and bills to represent the same value.

To prepare for this lesson:

To prepare for this task, the teacher should:

• Have at least one device per two students that has internet access. The activity will work best if there is a one-to-one device to child ratio.

• Ensure the Coinbubble website is not blocked.

• Watch the tutorial video and/or play the tutorial video for students in a whole-class setting.

See Accommodations Page and Charts on the 21things4students.net site in the Teacher Resources.

Directions for this activity:

1. Watch the tutorial as a whole class or direct students to the tutorial at:  https://www.gregtangmath.com/coinbubble

2. Have students play the Coinbubble game

Different options for assessing the students:

• Observations
• Check for understanding
• To assess a student’s mastery of the concepts presented in this resource, teachers could:
• Have students create a given monetary value using coins and bills.
• Have students create more than one way to represent a given monetary value.
• Have students create anchor posters of the different monetary exchanges.

MITECS: Michigan adopted the "ISTE Standards for Students" called MITECS (Michigan Integrated Technology Competencies for Students) in 2018.
