Overall Expectations
Area and Perimeter – Non-Standard Units
Grade 2
Students will
• Estimate, measure, and record length, perimeter, area, mass, capacity, time, and temperature, using non-standard units and
standard units (2m28)
• Compare, describe, and order objects, using attributes measured in non-standard units and standard units (2m29)
Specific Expectations
Students will:
• Estimate, measure, and record the distance around objects, using non-standard units (2m34)
• Estimate, measure, and record area, through investigation using a variety of non-standard units (2m35)
• Describe, through investigation, the relationship between the size of a unit of area and the number of units needed to cover a
surface (2m41)

Learning Focus
Measure and record the distance around objects
using a variety of flexible tools (e.g., ribbon,
string)
o transfer the flexible tool length to
non-standard units (e.g., take the ribbon
length and identify the number of equivalent
pencil lengths)
Measure and record the distance around
straight-sided objects using a variety of rigid
tools of non-standard units (e.g., popsicle stick
lengths)
Estimate, measure and record the distance
around objects using a variety of rigid tools of
non-standard units (e.g. pencils, popsicle sticks)
o measure a variety of sized spaces/objects
