Time and Money in Everyday Life

Students learn to tell time on analog and digital clocks to the hour and half hour, then to five-minute intervals. They explore calendar concepts including days of the week, months, and reading a date. For money, they identify coins and bills, learn their values, and count collections of mixed coins using skip counting. Real-world scenarios connect both skills to daily routines.

Time and Money in Everyday Life

Telling time and counting money are skills you use every single day. Let us learn how clocks work and how coins and bills add up!

Reading a Clock

An analog clock has a round face with numbers 1 through 12. It has two hands:

HandWhat It Looks LikeWhat It Shows
Hour handShort and thickThe hour (1-12)
Minute handLong and thinThe minutes (0-59)

Reading Minutes

The numbers on the clock also stand for groups of 5 minutes. When the minute hand points to 1, it means 5 minutes. When it points to 2, it means 10 minutes. Skip count by 5 around the clock: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60.

Worked Example 1: Reading the Time

The short hand is between 3 and 4. The long hand points to 6.

  1. Hour hand is past the 3 but not yet at 4, so the hour is 3.
  2. Minute hand on 6 means: skip count by 5 to the 6 gives 5, 10, 15, 20, 25, 30 minutes.
  3. The time is 3:30 (three-thirty).

A digital clock shows the time with numbers, like 3:30 or 10:15. The number before the colon is the hour. The number after is the minutes.

Coins and Bills

Dime10 cents10s
Quarter25 cents25s
Dollar bill100 cents (= $1.00)--

Worked Example 2: Counting Mixed Coins

You have: 2 quarters, 1 dime, 3 pennies. How much money?

  1. Start with the biggest coins. Count the quarters by 25s: 25, 50.
  2. Add the dime: 50 + 10 = 60.
  3. Count the pennies by 1s: 60 + 1 + 1 + 1 = 63 cents.
2 quarters + 1 dime + 3 pennies = 63 cents = $0.63

Worked Example 3: Making Change

A pencil costs 35 cents. You pay with 2 quarters (50 cents). What change do you get?

  1. Subtract: 50 - 35 = 15 cents.
  2. Your change is 15 cents, which could be 1 dime and 1 nickel.

Watch Out!

A dime is smaller than a nickel and a penny, but it is worth more! Do not judge a coin's value by its size. A dime = 10 cents, but a nickel = only 5 cents.

Counting Tip

When counting mixed coins, always start with the coins worth the most and work down: quarters first, then dimes, then nickels, then pennies. This makes skip counting easier.

Practice Problems

1. The short hand is on 7 and the long hand is on 12. What time is it?

Show Answer

7:00 (seven o'clock). When the minute hand is on 12, it means zero minutes -- exactly on the hour.

2. The short hand is between 10 and 11. The long hand is on 3. What time is it?

Show Answer

10:15. The hour is 10, and the minute hand on 3 means 15 minutes (skip count: 5, 10, 15).

3. Count the money: 1 quarter, 2 dimes, 4 pennies.

Show Answer

25 + 10 + 10 + 1 + 1 + 1 + 1 = 49 cents.

4. How many days are in 3 weeks?

Show Answer

3 x 7 = 21 days.

5. You have 3 quarters. Can you buy something that costs 80 cents?

Show Answer

No. 3 quarters = 75 cents, which is less than 80 cents. You need 5 more cents.
