# 2.9 - Time

The student will

• tell time and write time to the nearest five minutes, using analog and digital clocks.

### BIG IDEAS

• So that I will be able to read a clock for everyday life skills such as being on time
• So that I will be able to divide hours into five minute increments
• So that I can see the patterns of telling time

### UNDERSTANDING THE STANDARD

 Telling time requires reading a clock. The position of the two hands on an analog clock is read to tell the time. A digital clock shows the time by displaying the time in numbers which are read as the hour and minutes.Counting by fives is beneficial when telling time to the nearest five minutes.Students should develop an understanding that there are 60 minutes in an hour.The use of a demonstration clock with gears ensures that the positions of the hour hand and the minute hand are precise at all times.

### ESSENTIALS

 The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to Show, tell, and write time to the nearest five minutes, using an analog and digital clockMatch a written time (e.g., 4:20, 10:05, 1:50) to a time shown on a clock face to the nearest five minuteMatch the time (to the nearest five minutes) shown on a clock face to a written time
