# 1.9 - Time & Calendar

**The student will **

**investigate**the passage of time and

**tell time**to the hour and half-hour, using analog and digital clocks; and

b)

**investigate**the passage of time and**read and interpret**a calendar.*Adopted: 2016*

### BIG IDEAS

- So that I make it to resource on time (a)
- So that I get up in time for school (a)
- So that I know what resource I have today (b)
- So that I know what day it is today (b)
- So that I know what days are special events (i.e. my birthday) (b)

### UNDERSTANDING THE STANDARD

- Many experiences using clocks help students develop an understanding of the telling of time to the hour and half-hour, including:
- identifying the parts of an analog clock (minute and hour hands);
- demonstrating a given time to the hour and half-hour, using a model clock;
- writing digital time to the hour and half-hour;
- relating time on the hour and half-hour to daily routines and school schedules (e.g., bedtime, lunch time, recess time); and
- connecting the hour and half-hour to fraction concepts.
- Practical situations are appropriate to develop a sense of the interval of time between events (e.g., club meetings occur every week on Monday; there is a week between meetings).
- The calendar is a way to represent units of time (e.g., days, weeks, months).
- Using a calendar develops
the concept of day as a 24-hour period rather than a period of time from
sunrise to sunset.

### ESSENTIALS

**The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to**

- Identify different types of clocks (analog and digital) as instruments to measure time. (a)
- Tell time shown on an analog clock to the hour and half-hour. (a)
- Tell time shown on a digital clock to the hour and half-hour. (a)
- Match a written time (e.g., 1:00, 3:30, 11:00) to the time shown on a digital and analog clock to the hour and half-hour. (a)
- Read a calendar to locate a given day or date (e.g., What day of the week is the 10th? What date is Saturday?). (b)
- Determine the day/date before and after a given day/date (e.g., Today is the 30th, so yesterday must have been the __?). (b)
- Given a calendar, determine the number of any day of the week (e.g., How many Fridays are in the month of October?) (b)
