thousand and learn about 4-digit numbers.
a. Skip-count by thousands.
1a. Have students find the order where the
number increases by one each time you skip- 1,000 2,000 3,000 4,000 5,000
count by thousands.
In which place value do the numbers 6,000 7,000 8,000 9,000
change? The thousands place.
What is the order in which the numbers b. Skip-count by hundreds.
change? The number increases by one each
time. 9,100 9,200 9,300 9,400 9,500

1b. If you skip-count by hundreds, the 9,600 9,700 9,800 9,900
number increases by one each time.
c. Skip-count by tens.
1e. Have students see the need for another
place value after 9,999. 9,910 9,920 9,930 9,940 9,950
Have them skip-count by one as shown in 1d.
and write ten thousand as the next number 9,960 9,970 9,980 9,990
for 9,999.
Example: 10, 000 d. Skip-count by ones.
You write it as “10,000” and read it as “ten
thousand.” 9,991 9,992 9,993 9,994 9,995

9,996 9,997 9,998 9,999

e. What number comes after 9,999?

10,000

The number that comes after 9,999 is 10,000.
10,000 Ten thousand

2. Build Understanding

In question 1, the numbers generally increase. In question 2, have students solve a type of problem where
the numbers decrease and practice these kinds of skip-counting to familiarize them with “small numbers”
and “large numbers.”
Example: skip-counting by tens

a number, 4240 a number,
which is ten less which is ten more

4230 4250
