Activity Guide
The Primary Time Teacher™ (LER2995), with its new and improved design, will help your students make connections between analog and digital time- telling formats. The Primary Time Teacher™ is unique in that it has both an analog clock and a digital clock that work simultaneously. Turn the knob on the minute hand and watch both the synchronized hour hand and the digital numbers turn. The hours and the minutes on both the analog and the digital clocks are color coordinated so your students can make transitions between the clocks with ease.
The Primary Time Teacher™ can be used in a variety of learning environments. Place the clock in a learning center for students to explore or to use in directed activities. Your students will love to turn the hands, watch the mechanisms move, and learn to tell time making connections between analog and digital clocks.
Connections
Point out the hour hand on the analog clock. Ask the students to describe its features. Students might notice that the hour hand is short and that it is red. Then, ask students to guess which numbers on the digital clock are the hours. The hours are printed in red. Point out the minute hand and ask students to describe its features. Make connections between the color of the minute hand and the printed minutes on the digital clock.
Slowly turn the minute hand. Encourage students to describe what happens. Students should notice that the minutes change frequently on the digital clock, but the hours only change when a complete revolution has been made. Explore the relationship between how often the digital clock’s numbers change and the distance the minute hand travels.
Minutes
The Primary Time Teacher™ helps students find the number of minutes in an hour. Ask students if they know how many minutes are in an hour. Then, ask students how they can find out.
Discuss their suggestions and try them. The minute hand points to the tick marks around the edge of the analog clock. Ask students what they think these tick marks represent. (The space between each tick mark shows one minute.)
Count the tick marks on the clock. There are sixty minutes in an hour. As soon as sixty is reached, the minutes start all over again. Each time you move the minute hand, the minute numbers on the digital clock turn.
Hours
The Primary Time Teacher™ tracks both analog and digital time through a

Time Clocks
Time for play! The Primary Time Teacher™ is similar to a clock used often in work places everywhere. Encourage students to pretend they are going to work. They should tell the time they will arrive and show it on the clock. You can even make time cards for students to practice writing times in digital formats or in words. For example, students could write 15:00. Encourage students to punch in and out of class each day to practice modeling and telling times.
Elapsed Time
Use the Primary Time Teacher™ to practice elapsed time. Students should write down the time the "punch in" and the time they "punch out." Then, they can use the clock to find the elapsed time. Students can turn the crank and count the hours and minutes elapsed. Students could tell how long they were in a class, how long they spent on a particular task, or how long the were "at work."
