Grade 2 - Measurement
Standard 2.MT.1 - Practice reading analog clocks to the precision of 5 minutes.
Included Skills: Time
Attributes, Units, and Measurement Sense • choose benchmarks --in this case, personal referents -- for a centimetre and a metre (e.g., "My little finger is about as wide as one centimetre. A really big step is about one metre.") to help them perform measurement tasks; • estimate and measure length, height, and distance, using standard units (i.e., centimetre, metre) and non-standard units; • record and represent measurements of length, height, and distance in a variety of ways (e.g., written, pictorial, concrete) (Sample problem: Investigate how the steepness of a ramp affects the distance an object travels. Use cash-register tape for recording distances.); • select and justify the choice of a standard unit (i.e., centimetre or metre) or a nonstandard unit to measure length (e.g., "I needed a fast way to check that the two teams would race the same distance, so I used paces."); • estimate, measure, and record the distance around objects, using non-standard units (Sample problem: Measure around several different doll beds using string, to see which bed is the longest around.); • estimate, measure, and record area, through investigation using a variety of non-standard units (e.g., determine the number of yellow pattern blocks it takes to cover an outlined shape) (Sample problem: Cover your desk with index cards in more than one way. See if the number of index cards needed stays the same each time.); • estimate, measure, and record the capacity and/or mass of an object, using a variety of non-standard units (e.g., "I used the pan balance and found that the stapler has the same mass as my pencil case."); • tell and write time to the quarter-hour, using demonstration digital and analogue clocks (e.g., "My clock shows the time recess will start [10:00], and my friend's clock shows the time recess will end [10:15]."); • construct tools for measuring time intervals in non-standard units (e.g., a particular bottle of water takes about five seconds to empty); • describe how changes in temperature affect everyday experiences (e.g., the choice of clothing to wear); • use a standard thermometer to determine whether temperature is rising or falling (e.g., the temperature of water, air).
