Color-coded time
This lesson introduces telling time to the minute using the analog and digital clocks. The hands are color-coded to assist with hour and minute hand discrimination. The student will use the time on the digital clock, which can then be transferred to the more difficult analog clock.
A lesson plan for grade 3 Mathematics
Learning outcomes
The goal of this lesson is to teach the students to transfer the numbers read from the color-coded digital clock face to the color-coded analog clock in order to tell time to the minute.
Teacher planning
Time required for lesson
45 minutes
Materials/resources
- Small, manipulative mini-clocks for the students with a red hour hand and blue minute hand
- One large demonstration clock for the teacher.
- digital clock faces on cards
- Worksheet with clock faces to be drawn on the page without the hands present.
Pre-activities
The students will be able:
- To count by 5’s using the numbers on the analog clock face and tell time to 5 minute intervals.
- To add one, two, or three to a number less than 59 (ex. 55 + 2= 57).
- To recognize and discriminate the red and blue hands as hour and minute hands.
- To recognize which direction is clockwise motion.
- To read the numbers on the digital clock face, such as 1:30 or 1:35, etc.
Activities
The teacher will demonstrate with mini clocks and/or digital clock cards:
- The students will review counting by fives around the analog clock face.
- Clockwise rotation of the clock hands.
- Red is the hour hand and the black is the minute hand.
- Digital clock face is red for hour (colon): black for minute.
- Teacher demonstrates with the large clock on five minute intervals, and the students are asked to add one to the number. (For example, 1:35 plus one equals 1:36). Students demonstrate with the mini clocks.
- Match the digital clock cards with a mini clock on the five minute intervals.
- Use digital clock card face with hour and specific minutes to set the mini clock to match. (see attachment below)
- Counting by 5’s clockwise motion and add (+1) or add(+2) to set the clock accurately to the minute (ex., 1:31, or 1:32).
Guided Practice
- Worksheets for the students to make the digital clock cards match the analog mini clock. (see attachment)
- Hands on a clock are provided and the students must write the correct time to the minute on the digital clock line.
- Any combination of transferring time in analog and digital forms using the color-coded concept.
Assessment
Hands on a clock are provided and the students must write the correct time to the minute on the digital clock line.
Teacher shows a time to the minute on the demonstration clock and the students must write the correct time on their paper as a digital clock face, for example: ___:___ (hour is written in red and minute is written in blue)

Extension Activities:
The teacher states a hypothetical time word problem and have the students solve using the mini clocks in analog or digital. For example, Johnny arrived at the bus stop at 2:35. If he boarded the bus two minutes later, what time did he board?
