Curriculum – Measurement
For students to measure and compare length, mass, capacity, area, temperature of objects/materials, and the passage of time, using non-standard units, through free exploration, focused exploration, and guided activity.
Students and the teacher begin by sitting on the floor. Students should have some previous experience with clocks and telling time.
- Pre-cut circles – one for each student (Appendix A)
- Long thin strips of paper to make the hour and minute hand – one for each student
- Pencils and Markers
- Butterfly clips
For Appendices download the lesson plan here.
- Explain that you are going to make clocks today.
- Review the different parts of the clock – round face, numbers, cardinal numbers (12, 3, 6, 9).
- Review the position each cardinal number on the clock.
- Take students through the steps necessary to make their clock accurately.
- First they will need to fold their clock in half to get the exact position of the cardinal numbers 12 and 6. Then they will need to fold their clock again to get the exact position of the 3 and 9.
- Students are instructed to put little pencil notches or markings and the appropriate number at that spot.
- Show students how to mark the rest of the numbers on the clock. Keep the following in mind:
- Students need to ensure the distance between each number is close to equal. Have students put notches at the spots where numbers should go before writing in the numbers. Ask students to check with an adult regarding their notches to ensure equal spacing before beginning to write the numbers.
- Explain that when students begin to write the rest of the numbers in pencil on the clock that the number 12 should always be facing them to avoid having numbers turned to the side and upside down.
- When students have completed writing the numbers in pencil and checked with an adult to make sure the numbers are all facing the right way, students can go over the pencil in marker to make the numbers stand out.
- Students then take a long strip of paper and cut the minute and hour hand. Remind students that the hour hand must be shorter than their minute hand.
- Students must find an adult to pierce a hole through the center of their clock, hour and minute hand.
- A butterfly clip can be threaded through the hands and clock.
- Allow students to play/explore with their finished clocks.
