Metric-ominoes Game

Introduction

Make learning metric prefixes and their corresponding numerical values entertaining and enjoyable with this metric units version of the classic dominoes game.

Concepts

• Metric system
• Metric prefixes
• Conversion factors

Background

The metric system of measurement is based upon divisions of 10 using the same prefixes for length, mass and volume. Most countries today use this system for all their measurements. Why does the United States still use the English system of measurement? The United States was mainly developed from English heritage, so it ended up with the English measurement system. Several attempts have been to promote the use of the metric system in the United States, but all have failed due to strong public sentiment for the English system. Ironically, the British and their Commonwealth countries now use the metric system of measurement, but the United States, for the most part, still holds onto the English system. One area that does use the metric system as a standard is the field of science. The metric system is the foundation for most measurements and calculations used in all divisions of science. The Metric-ominoes Game will introduce and help strengthen students’ knowledge of the metric system and their ability to carry out conversions between the prefix of a measurement and its corresponding numerical value. The eight most commonly used prefixes—mega, kilo, deka, deci, centi, milli, micro and nano—will be used in this game. A table of the prefixes and their numerical values is listed below, and may be reproduced and given to students if desired.

Materials

Safety Precautions

The materials in this kit are considered nonhazardous. Please follow all normal classroom guidelines.

Prelab Preparation

1. Make a copy of the Metric-ominoes Rules for each student.
2. Cut out the set of tiles from the transparency. These tiles can be used on an overhead projector to explain the rules and play of the game.
3. (Optional) Make copies of the conversion table sheet. Cut out the individual conversion tables. These can be given to each student.

Procedure

1. Divide the students into groups. The group’s size can range from three students to five students.
2. Hand out a set of Metric-ominoes tiles to each student group and give each student a copy of the game instructions.
3. Review the game rules with the students.
4. Go over an example of play using the overhead projector and the transparency tiles.
5. When ready, instruct students to begin the activity.

Teacher Tips

• The tile cards may be laminated to increase durability and allow for extended use.
• Enhance the game by giving a prize or extra credit to the student who uses up all of his or her tiles first. Instruct students to start their games simultaneously so there is no unfair time advantage to any group.
• Students may or may not be allowed to use a conversion table.
• Use the Table of Conversion Units (Prelab Preparation section) to confirm matches.
• This activity can be completed in one 50-minute class period.
