Measurement

In Grade 2, students develop their understanding of measurement concepts and skills. They learn to measure length, time, and money using appropriate tools and units, and begin to understand the relationship between different units of measurement.

Grade Two Expectations for Measurement

Essential Learning Outcome 1: Understanding What and How We Measure

Choose and use non-standard units appropriately to measure lengths
Describe the inverse relationship between the size of a unit and the number of units needed
Explain the relationship between centimeters and meters as units of length
Use benchmarks for these units to estimate lengths
Measure and draw lengths in centimetres and metres, using a measuring tool
Recognize the impact of starting at points other than zero
Use units of time, including seconds, minutes, hours, and non-standard units, to describe the duration of various events
Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
Count a mixed collection of coins whose sum is less than or equal to one dollar

Specific Curriculum Outcomes

By the end of Grade Two, the learner will be expected to:

Inclusive Assessment Strategies

Assessment strategies that provide information about learning:

Teacher Content Knowledge

The measurement strand is mathematically powerful, and it enables the identification and quantification of attributes of objects so that they can be compared and ordered. It plays a crucial role in everyday life and it provides a link among the different strands of mathematics. It is important for students to understand linear measurements and their attributes, how to measure them accurately and use the appropriate units and tools of measurement. They will develop the skill to measure objects using units.
