Step 4 · Place value to 1,000 topics
Read clocks to the nearest five minutes, use a.m. and p.m., and count coins and dollars.
Time to five minutes
The minute hand takes 5 minutes to move from one number to the next. So count by 5s around the clock from 12: the 1 is 5 minutes past, the 2 is 10, the 3 is 15, and so on to the 11 at 55.
| Long hand on | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Minutes past | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 | 55 |
Read the hour from the number the short hand has passed. At 7:45 the short hand is nearly at 8, but it has not reached it, so the hour is still 7.
a.m. and p.m.
A day has 24 hours, and the clock goes round twice. Times from midnight to noon are a.m.: the morning. Times from noon to midnight are p.m.: the afternoon and evening.
- Breakfast at 7:30 a.m.
- Lunch at 12:15 p.m.
- Bedtime at 8:00 p.m.
Counting coins and dollars
Each coin has a value in cents (¢): a penny is 1¢, a nickel 5¢, a dime 10¢ and a quarter 25¢. A dollar is 100¢, written $1.00.
To count a mix of coins, start with the coins worth most, then count on: quarters by 25s, dimes by 10s, nickels by 5s, pennies by 1s.
Example: Counting on
How much are 2 quarters, 1 dime, 2 nickels and 3 pennies?
- Quarters: 25, 50.
- Dime: 60.
- Nickels: 65, 70.
- Pennies: 71, 72, 73.
