## Lesson: Time

Developing the Concept

Review the concepts taught in Introducing the Concept. Explain to children that today they will learn about telling time to the hour. When children understand the concept of hour, you may then introduce the minute hand, adapting the lesson for the minute hand.

**Materials:** A demonstration clock with only the hour hand and another clock with both hands. If you can prepare clocks for each child, prepare one with the hour hand and one with both hands.

**Preparation:** Make a clock to use on the overhead projector, using three sheets of acetate. On one, draw a clock face with no hands. Cut a small hole in the center and put a brad through it from the back side, but do not spread the prongs. Cut out the other two circles, one the radius of the hour hand and one the radius of the minute hand. Draw the appropriate hand on each circle. Cut holes in the center of each circle. For the beginning of the lesson, place only the circle with the hour hand on top of the clock face. You could also use a demonstration clock with the minute hand removed.

**Prerequisite Skills and Concepts:** Children should be able to count from 1 to 12. They should have had experience with sequencing events, duration of events, and the vocabulary terms *first, next, last, long time, short time, before, after, same time, day, night.*

**Wrap-Up and Assessment Hints**

Children will need many experiences telling time with a clock. Take the opportunity often throughout the day to return to the clock and talk about the time. Use the vocabulary *o'clock,* *a little before,* *a little after,* and so on. Keep a demonstration clock out at all times and encourage children to practice using it, thereby building children's understanding of time.
