Telling Time to the Hour and Half Hour

Grade 2 · Math · Study Guide

Learn to read clocks and tell time to the hour and half hour.

A clock has two hands. The short hand is the hour hand and it points to the hour. The long hand is the minute hand. When the minute hand points straight up to the 12, it is exactly on the hour — like 3 o'clock.

When the minute hand moves halfway around the clock and points to the 6, it is a half hour past. If the hour hand is between the 3 and 4, we say it is 3:30. The ':30' tells us it is thirty minutes past the hour.

Clocks can be analog (with hands) or digital. On a digital clock, 7:00 means 7 o'clock and 7:30 means seven thirty. Knowing how to tell time helps you get to school on time, know when lunch is, and plan your day like a pro!
