Estimating & Measuring the Dimensions of an Object Establishing Relationships Between Units of Measure for Length
Learning Goal Today we will be learning about different units of measure so that we can understand the relationship between different units of measure for length. We’ll know we’ve got it when we are able to estimate and measure the dimensions of an object using conventional units.
Vocabulary Centimetre Decimetre Equivalency Fraction Kilometre Length Millimetre Natural Number Perimeter Unit of Measure Width
Measuring Length The international system of units is used for measuring length. The metre is the base unit for this system. Kilometre Hectometre Decametre Metre Decimetre Centimetre Millimetre km hm dam m dm cm mm
Representing Length Units of measure represent length in a precise way There are units for smaller objects and units for bigger ones
Representing Length Unit of Measure Useful for Measuring… Millimetre (mm) Length of an ant Thickness of a piece of string Centimetre (cm) Length of a magnifying glass Thickness of a sandwich Decimetre (dm) Height of a microscope Length of a hand Metre (m) Size of a building Dimensions of a classroom Kilometre (km) Distance between 2 cities
