# Numbers with Whole ThousandsFree lesson for 4th grade math

On this number line you see whole thousands from one thousand to fifteen thousand.

The colored digits are the “thousands period” and count as the whole thousands. Read the colored digits as its own number. Say the word “thousand” for the comma.

We continue with whole thousands until reaching a thousand thousands.

That number has a new name: one million.

 7 8,0 0 0 Read:  78 thousand 1 5 3,0 0 0 Read:  153 thousand 8 0 2,0 0 0 Read:  802 thousand 9 9 0,0 0 0 Read:  990 thousand 9 9 9,0 0 0 Read:  999 thousand 1,0 0 0,0 0 0 Thousand thousand = 1 million

The rest of the digits tell us our hundreds, tens, and ones
just like you have learned.

 1 7,5 4 4 Read:  17 thousand five hundred forty four 6 0 9,2 3 0 Read:  609 thousand two hundred thirty 7 0,0 8 0 Read:  70 thousand eighty 9 0 2,0 0 5 Read:  902 thousand five

1. Place a comma in the number. Fill in the missing parts.

 a.  1 6 4 0 0 0 ______ thousand b.  9 2 0 0 0 ______ thousand c.  3 0 9 0 0 0 ______ thousand d.  3 4 0 0 0 ______ thousand

2. Place a comma in the number. Fill in missing parts. Read the numbers aloud.

 a.  1 6 4,4 5 3  164  thousand  453 b.  9 2 9 0 8 ______ thousand ______ c.  3 2 9 0 3 3 ______ thousand ______ e.  5 5 0 0 5 3 ______ thousand ______ f.  7 2 0 0 1 ______ thousand ______ g.  8 0 0 0 0 4 ______ thousand ______

 a. 456,098       e. 78,304 b.  950,050 f.  266,894 c. 23,090 g. 1,000,000 d. 560,008 h. 306,700

4. Think in whole thousands and add!

 a.  30,000 + 5,000 =         think: 30 thousand + 5 thousand b.  200,000 + 1,000 = c.  400,000 + 30,000 = d.  710,000 + 40,000 = e.  300,000 + 700,000 = f.  700,000 + 70,000 =

5. Add and subtract, thinking in whole thousands.

 a.  35,000 + 5,000 = b.  711,000 + 10,000 = c.  420,000 + 30,000 = d.  700,000 –  70,000 = e.  300,000 –  60,000 = f.  1,000,000 – 200,000 = g.  30,000 – 5,000 = h.  200,000 –  6,000 = i.  723,000 – 400,000 = j.  500,000 – 1,000 =

6. On the number line below, 510,000 and 520,000 are marked (at the “posts”).
Write the numbers that correspond to the dots.

7. Make a number line from 320,000 to 340,000 with tick-marks at every whole
thousand, similar to the one above. Then mark the following numbers on the
number line:
323,000   328,000   335,000  329,000  330,000
