What this worksheet covers

Grade: Grade 3 (Elementary School)
Topic: Time and Duration

Children trace the clock face to read the time ○ Minutes After and ○ Minutes Before a given moment. Seconds arrive as a new unit, bringing conversions such as minutes to seconds and seconds to minutes and seconds, plus word problems asking for Time Taken, The Later Time and Total Time (Minutes, Seconds).

Treating an hour as 100 minutes is the most frequent error, turning 30 minutes after 9:50 into 9:80 or 10:80. A minutes figure above 60 identifies it. In ○ Minutes Before problems, adding where subtracting was needed sends the time forward instead of back.

The units in play increase, and calculations with time become more fine-grained. Expressing a time as a number has stayed unchanged since Time and Duration in grade 2. This way of looking at time changes shape in grade 6, resurfacing in The Structure of Measurement Units as time rewritten using fractions.
