·       Applying relationships among kilometres/ hectometres/ decametres/ metres/ decimetres/ centimetres/ millimetres, litres/ millilitres, and kilograms/ grams

·       Using relationships to rename measures

·       Applying referents for various measurement standards (e.g., 30 cm is like  a ruler, 1 dm is about a small hand span) 

 SI Measurement: pattern in changing units

·       Understanding that a smaller measurement unit increases the number of those units and that a larger measurement unit decreases the number of those units 

·       Apply the above relationship to reason through conversions

·       Understanding the relationship between metric prefixes will help students in many measurement situations
