THIRD GRADE-FIRST HALF*

READING AND WRITING NUMBERS

1. One hundred one is written 101. Write in figures: one hundred four; one hundred seven.

2. Read; then write in words: 103, 105, 107, 109. 3. Add 100 to 100. The sum is two hundred, written 200. Add 200 to 100. The sum is 300.

4. Read; then write in words: 400, 500, 601, 700, 802, 900, 501, 404.

Read; then write from dictation:

The largest number that can be written with three figures is 999. The next number is one thousand, written 1000.

The first figure on the right is called the ones' figure; the next is called the tens' figure; the next is called the hundreds' figure; the next is called the thousands' figure. The tens are always read as so many ones. Thus, 625 is read, " 6 hundred 25." In 25, the 2 tens

are read as 20.
