## Making a clock

#### Materials

12 sheets of laminated paper or tag board with the numbers 1-12

12 sheets of laminated paper or tag board with the numbers 0, 5, 10, ... 55

1 long arrow (minute hand)

1 short arrow (hour hand)

White board, dry erase marker

1 large clock face with hands that can be moved to different positions

Small clock faces with hands that can be moved to different positions (1 for each pair of students)

A cut-out circle with the sun on one side and moon on the other.

#### Actions

The students sit in a large arc/rainbow. The teacher explains that they are going to make a giant clock to practice telling time.

The teacher shows students a clock and asks what numbers they see on it. After students respond, the teacher has students help position the tag board sheets with the numbers 1-12 in a circle on the floor to represent a clock. Students count from 1 o'clock through 12 o'clock as the numbers are laid out.

Then the teacher says,

There are 60 minutes in an hour. When the minute hand goes from one number to the next, that means five minutes have passed. It starts on the 12; that means 0 minutes have passed.

Then the teacher has a student put the paper with the 0 below the paper with the 12 on it. Next, the teacher models counting by 5's, having a student place the corresponding number of minutes below each of the numbers 1-11.

Then the teacher says,

When the minute hand reaches 12 again, that is 60 minutes, and one hour has passed. Now the count starts over for the next hour.

The students and teacher can count by 5s together pointing to each of the numbers 1-11.

The teacher then discusses the hour and minute hands and shows how they move in a clockwise direction. The teacher models moving the hands to show time to the hour and half hour.

In pairs, the students create the same time on their mini-clocks. The teacher guides the students in telling the times to their partner and shows them how to write the times on the whiteboard in both word format (i.e. eight o'clock) and digital format (8:00).

Once students have demonstrated proficiency in identifying what time it is, the teacher uses the moon/sun icon to show that the same time can occur at night or during the day. For example, she can model 12:00 lunchtime and hold up the sun icon, and model 12:00 while the students are in bed and hold up the moon icon. This can be extended with other events that are relevant to the students' lives.

over 4 yearsI like this idea of building a clock together. I've taught telling time for 7 years and my students respond the best to the concept in this order... 1) The hour hand is the little hand and little hands get to go first. So in the time 2:30, the 2 is the little hand. 2) The minute hand is the big hand and big hands go second. 3) The beginning of the day is 12:00, which is tricky, because you would think it would be called 0:00. 4) If you count to 60 one time, that is roughly one minute. The little hand would move only 1 line. 5) Then I teach just the hours, like 1:00, 2:00, etc. 6) Then I teach the half hours. The most important part is that they understand why straight down is :30. We label every minute line around the clock so they see there are 30 lines to get straight down. Then we talk about how the hour hand starts to head toward the next hour as the minutes go by. This seems to stick with them conceptually.

over 5 yearsWorking with the hour hand first really helps students to interpret analog clocks and understand why the placement of the hour hand matters. I found that students were able to estimate the time as "half-past 2" when the hour hand was between the 2 and 3. Representing the clock at the half hour was such a common misconception on student work and assessments that I just addressed the hour hand first and it really improved student work and representations. I found my first graders placing the hour hand first and then adjusting the minute hand to represent 30 minutes. The other time phrases students began to use regularly were "Just past the hour", "almost 3 o'clock", "halfway to 3 o'clock".
