Objective
Learners read a digital clock at :00, :15, :30, or :45 and say the time in words by choosing an hour word and a minute word.
What this practice covers
Learners see a digital clock showing a time on the hour or at a quarter hour, such as 2:15. They choose the hour word from three choices, then choose the minutes from o’clock, fifteen, thirty, and forty-five. Together the two choices say the time aloud, as in two fifteen. Choose a 5-question Quick check or a 15-question Practice session; the difficulty progression adjusts to the selected length.
Standards alignment
Prepares for Common Core: CCSS.MATH.CONTENT.2.MD.C.7 — Tell and write time from analog and digital clocks to the nearest five minutes.
Who it’s for
This practice is designed for Grade 1 learners building an early understanding of clocks and time. It is also useful for older learners who want a calm visual review of how hours and minutes are represented.
What to know first
- Learners should recognize numerals through 12 and understand that a clock describes an hour and a number of minutes after that hour.
Difficulty and scaffolding
Developing · Representational stage
Problem representations
- Digital clock
Three worked examples
- 5:00 is read as five o’clock. Choose five for the hour and o’clock for the minutes.
- 2:15 is read as two fifteen. The 15 after the colon is the word fifteen.
- 9:45 is read as nine forty-five. Read the 45 after the colon as one number, forty-five.
Likely misconceptions
- Learners may read the minute digits one at a time, as in “one five” for 2:15, or choose o’clock for 3:30 because it ends in a zero. Read the hour before the colon first, then read the two digits after the colon together as one number.
Hints and explanations
- 5:00 is read as five o’clock. Choose five for the hour and o’clock for the minutes.
- 2:15 is read as two fifteen. The 15 after the colon is the word fifteen.
- 9:45 is read as nine forty-five. Read the 45 after the colon as one number, forty-five.
What to practice next
Next, practice digital time to the minute, where the minutes can be any number from 1 to 59.

Digital time to the quarter hour FAQs
What does digital time to the quarter hour teach?
It teaches learners to read a digital time in two parts and say each part in words. The hour comes before the colon, and the minutes after it are always 00, 15, 30, or 45.
Why does the quiz use only 00, 15, 30, and 45 minutes?
These quarter-hour times use only four minute words. Learners can practice reading a time in two parts with a small set of words before the next quiz adds any minute from 1 to 59.
Should telling-time practice be timed?
No timer is necessary. Accuracy and explanation should come first. Ask the learner to read the hour, read the minutes, and then say the whole time aloud to check it.
How can an adult help after a mistake?
Have the learner point to the digits before the colon and say the hour, then point to the digits after it and say the minutes. Keep the correction brief and let the learner retry the same problem before showing the answer.
