Seconds, Minutes, HoursOrder the units seconds, minutes, and hours and know 60 seconds make a minute.Time comes in three sizes: seconds are quickest, minutes are longer, and hours are longest. They fit together, with 60 seconds in a minute and 60 minutes in an hour.
Which Takes LongerCompare durations and match everyday activities to the right time unit.The activity that uses more time takes longer. Sorting tasks into seconds, minutes, or hours makes it easy to see which ones are quick and which are long.
Ordering by TimeOrder activities from quickest to longest by how long they take.Activities can be ordered from quickest to longest, like a clap, then eating lunch, then sleeping all night. Comparing their time units puts them in order.
Time Compare PracticeCompare which of two activities takes longer using their time units.Putting it together, you compare durations by their units: hours beat minutes, and minutes beat seconds. This lets you say which of two activities takes longer.
