Overall Expectations
By the end of Grade 2, students will:
• estimate, measure, and record length, perimeter and area using non-standard units and standard units
• compare, describe, and order objects, using attributes measured in non-standard units and standard units

By the end of Grade 3, students will:
– estimate, measure, and record the perimeter of two-dimensional shapes, through investigation using standard units (Sample problem: Estimate, measure, and record the perimeter of your notebook.)
– estimate, measure (i.e., using centimetre grid paper, arrays), and record area (e.g., if a row of 10 connecting cubes is approximately the width of a book, skip counting
down the cover of the book with the row of cubes [i.e., counting 10, 20, 30, …] is one way to determine the area of the book cover)
