Grade 3 - Measurement and Data
Standard 3.MD.1.3 - Practice finding the appropriate length of various objects. Understand the approximate scale of different metric units.
Included Skills: Measurement
Students will be expected to demonstrate an understanding of measuring length (cm, m) by • selecting and justifying referents for the units centimetre or metre (cm, m) • modelling and describing the relationship between the units centimetre or metre (cm, m) • estimating length using referents • measuring and recording length, width, and height • Performance Indicators - M03.01 Provide a personal referent for one centimetre and explain the choice. - M03.02 Provide a personal referent for one metre and explain the choice. - M03.03 Match a given standard unit to a given referent. - M03.04 Show that 100 centimetres is equivalent to 1 metre by using concrete materials. - M03.05 Estimate the length of an object using personal referents. - M03.06 Determine and record the length and width of a given 2-D shape. - M03.07 Determine and record the length, width or height of a given 3-D object. - M03.08 Draw a line segment of a given length using a ruler. - M03.09 Sketch a line segment of a given length without using a ruler.
