23. Game: "I Have a Number in Mind"

Let one child be leader in this game. He will say, "I have a number in mind. If I add 4 to it, I shall have 7. What is the number?"

The child who answers correctly becomes leader.

This leader may say, "I have a number in mind. If I take away 6, I shall have 3. What is the number?” Continue the game in this way.

24. Children Playing School

One of you may be teacher today. The one who is chosen asks questions like these:

1. I had a dime and spent 6¢. What have I left? 2. Mary gave me 4 marbles and I already had 6. How many have I now?

3. Mother gave me a nickel, brother gave me 3 cents, and John, 1 cent. How much money have I? 4. I live one mile from school. How far do I walk each day going to and from school?

5. John lives 4 blocks from school. How far does he walk each day going to and from school?

6. How much are 4 and 2?

7. William bought a horn for 5 cents, a soldier for 3 cents, and a top for 2 cents. What did the three toys cost?

8. The leader will give any questions he thinks the class can answer.

This is a way for two teams to play bean bag. Your teacher appoints a captain for each team. These captains choose sides. The teacher then pins red badges on one team and blue badges on the other.

The children in the teams take turns in throwing the bean bag. A bag in the outer circle counts 10; in the next circle, 20; and one in the inner circle, 30.

The Red and Blue teams have just finished a game. One of the captains is checking the addition.

Tell which side won. By how much did it win? Play this game and keep the scores as shown in the picture. Change the numbers often.

John puts all the money he has saved in his toy bank each week. Once he had a large number of pennies to count. He counted them by ones and found that he had 50 cents.

"I can show you an easier way to count your pennies," said Mary. "Put ten pennies in each pile."

John did that.

"How many pennies have you in the first pile?" asked Mary.

"Ten," replied John.

"You may call that pile 1 ten," said Mary. "In 2 piles you have 2 tens."

"Yes," said John, "and in 3 piles I have 3 tens. In 4 piles I have 4 tens, and in 5 piles, 5 tens."

After that John always counted his money in this easy way. He liked to count by tens.

1. One ten is written 10.

2. When we write 2 tens, we write 20.

3. We call 2 tens twenty.

4. How do we write 3 tens?

5. How do we write 4 tens?

We call 3 tens thirty.

We call 4 tens forty.

6. Write fifty; sixty; seventy; eighty; ninety. 7. Write by 10's from 10 to 100; from 100 to 10.

28. Using Tens in Keeping Score

Here is another way to play the bean bag game.

Draw one circle on the floor and use ten bags. Each bag in the circle will count 10; a bag outside the circle or on the line will not be counted.

1. These are the records of some children who played the game in this way. Give the score of each child:

29. Using Fives in Keeping Score

1. Play the bean bag game again, using ten bags.

This time you may let each bag count 5.

2. Add the scores given below and tell how many

1. One week John put a dime and one cent in his bank. He put in eleven cents.

Ten and one are eleven. It is written 11.

2. The next week John put in a dime and two cents. He put in twelve cents.

Ten and two are twelve. It is written 12.

3. The left-hand figure shows the tens and the righthand figure shows the units.

4. How many are ten and three? Write that number. Which figure stands for the ten? Which stands for the units?
