38. Finding Differences in Weight

Children of your age should weigh about 56 pounds. Mary, who is of this age, weighs 44 pounds. How much underweight is she?

1. Find out how much below or above average

weight these children are:

John 66 pounds.

Ellen 42 pounds.

Mary 68 pounds.

James 76 pounds.

2. See if your weight is below or above 56 pounds.

2. Count by 2's from 2 to 50; 52 to 80; 82 to 100. 3. Write in words the numbers from one to twenty. 4. Beginning with 2, count by 2's to 100 and write the numbers as you count.

5. Beginning with 5, count by 5's to 100 and write the numbers as you count.

6. Count by 10's from 10 to 100. Write the numbers.

40. A Relay Race

Your teacher will write these numbers on the blackboard. They may be used for relay races in both addition and subtraction.

Divide your class into two teams with a captain for each team.

At a signal the captains run to the board and write the answers to the examples at the opposite ends of the line.

Each captain then gives the chalk to the pupil next in line. As each pupil receives the chalk, he runs to the blackboard and writes his answer, and passes the chalk to the team-mate next in line.

The team that writes the greatest number of correct answers and finishes first wins the game.

41. Telling Time

1. Read the figures on the clock. Which hand tells the hours? Which hand tells the minutes?

8

6 5

ය

It is 12 o'clock.

2. When both hands point to 12, it is 12 o'clock. When the short hand points to 1 and the long hand points to 12, it is 1 o'clock.

3. The long hand goes all the way around the face of the clock in 1 hour. It goes half way around the face of the clock in half an hour. It goes one quarter of the way around the face of the clock in a quarter of an hour.

4. What time is shown by each of the clocks on this page and the next?

5. Make a toy clock face and fasten hands on it with a pin, or bring an old clock to school. Show by your clock the time you get up.

6. Show the time you go to school; you go to bed.

7. Move the clock hands to show what John did on his busy day:

He got up at 7 o'clock.

He had breakfast at half past 7.

He went to school at half past 8.

He had lunch at 12.

He went home at quarter past 3.
He played until 5.

He brought in wood at half past 5.
He had supper at quarter past 6.
He went to bed at half past 8-

Here are two clocks. Are they alike? Find the difference.

Make two clock faces like these. Set both clocks at one o'clock. Set them at 6 o'clock. Set them at seven o'clock.

Now set both clocks for your busy day, showing when you do different things.

What have you found out by doing this?

Can you write to twelve in two ways?

The numbers you wrote in the new way are called Roman numbers.
