Metric Conversion Game

Fifth Grade Math Activities: Metric Conversion Game

What You Need:

  • 1 sheet white paper
  • 1 black marker
  • 1 friend

What You Do:


1. Let your child draw a standard nine-square tic-tac-toe grid on the sheet of white paper using the black marker.

2. Have your kid use the left side of the following chart and the black marker to fill each of the squares in the grid randomly. This chart can also be the gamekeeper's cheat sheet during game play.

1 millimeter = 0.001 metre

1 centimeter = 0.01 metre

1 decimeter = 0.1 metre

1 decameter = 10 meters

1 hectometer = 100 meters

1 kilometer = 1000 meters

You'll want to fill it out in such a way that each square contains a single figure. For example, you could write MillimeterIn the top left square, DecameterIn the top centre square, CentimeterIn the top right square, 100 metersIn the centre square and so on. Try to be as random as possible.

3. To play the game, your child and her friend should decide who will go first.

4. The child who goes first should pick a random square and then try and convert it to or from meters. For example, if she picks a square that contains the term hectometer, she needs to correctly guess how many meters a hectometer equals.

5. If she guesses correctly, she gets to write an X or an O in the square.

6. Then, the next child should take his turn.

7. The game continues until someone gets three squares in a row. Whoever gets three squares in a row first—wins!

8. The best part is that this game could easily be converted to other metric measurements (liters, grams) instead of meters for added replayability.

Maths Review:

Here are some more conversions in case you want to mix it up a little:

  • 1 m = 10 dm (For example, 4 m x 10 = 40 dm)
  • 1 m = 100 cm (For example, 4 m x 100 = 400 cm)
  • 1 m = 1000 mm (For example, 4 m x 1000 = 4000 mm)
  • 100 m = 1 hm (For example, 4 m / 100 = .04 hm)
  • 1000 m = 1 km (For example, 4 m / 1000 = .004 km)
