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:

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.
