Learning objects The Metrix: asteroid: decimals

TLF ID L8150

Captain the Metrix spacecraft on its mission to save Earth from an asteroid collision. Use the metric measurement tables for mass, length and volume to help you make metric unit conversions involving decimal numbers. Some of these will involve rates, such as speed and frequency. (For example, to blow up the asteroid, find the spacecrafts's speed in km/ms that matches the asteroid's speed of 24 km/s.) Beat two other spacecraft to the asteroid to save Earth. This learning object is the sixth in a series of six learning objects.



Educational details

Key learning objectives
  • Students apply knowledge of relationships in metric measurement by converting between units of mass, length and capacity.
  • Students interpret terminology for mass, length and capacity to solve problems involving other units and rates.
Educational value
  • Provides opportunities for students to transfer their knowledge of converting units of measurement for mass, length and volume, involving decimal fraction calculations, to rates and other measurement units.
  • Presents metric tables that show the relationships between units, and highlight decimal place value concepts.
  • Provides feedback that supports the development of strategies for conversion between units.
  • Encourages repeated use by providing three random sets of tasks.

    Platform requirements
    • This object may not display correctly on the Mac OS X platform in Safari unless viewed with Flash 9 Player 9, 0, 24 (for Safari). Use of earlier increments of the Flash 9 Player may result in playback issues on both PowerPC and Intel based hardware. Indications of an incompatible player are looping and/or flashing animations which are likely to relate to flawed interaction with the API or rendering engine. Due to the use of rich media content, this learning object is suitable for a connection speed of 256 kbit/s or faster.
