Note to Grade 6 students: Use Australian spelling for these measurement terms – Metre and litre (not meter or liter as listed in these international image sources).

Working with measurements can be tricky. Visualising can help.

Often students have difficulty remembering which is bigger, kilo or milli-. Using a graphic organiser such as this can be helpful. Students can see the visual connection for the larger portion of the chart, kilo, shrinking to the smaller, milli-.

Working with patterns, multiples of 10, and shifting decimals is another strategy to help students complete conversions between larger and smaller units. Connecting to decimal work with multiplication and division patterns in previous work builds confidence with this new concept.

Using conversion factors is an additional strategy. A conversion factor is a rate in which two quantities are equal but use different units. Make sure to use the correct conversion factor. The units you are converting from should divide out, leaving you only with the units you are converting to.

All of the different strategies may take practice. Doing one practice problem may not be enough. You may need to practice to develop proficiency. Like most things in life you may have to work and practice these skills in order to improve but the effort is worth it.

Stop right there! Right now on the Maths page on this blog is a great resource ready for you to download! Yes it is a chart explaining the King Henry strategy which employs the greek words kilo, hecto, deca, unit, deci, centi and milli to explain our measurement system and HELP YOU with ALL measurement conversions!

Remember though,

1cm = 10mm

Multiply when converting to the right (and move that decimal place accordingly)

Divide when converting to the left (and move that decimal place accordingly)
