Skip Counting by 2s, 5s, 10s to 120 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. fives
2. tens
3. twos
4. skip
5. count
6. pair
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 20, 30, 40, 50, 60
This pattern adds 10 each time, so the number between 40 and 60 must be 50.
2. 5, 10, 15, 20, 25
Counting by 5s, we add 5 to 10 to get 15, which fits right before 20.
3. 2, 4, 6, 8, 10
The numbers jump by 2 each time, so 4 plus 2 gives us 6.
4. 70, 80, 90, 100, 110
Each number grows by 10, so after 100 the next number is 110 — that is ten tens plus one more ten.
Part C: True or False?
Read each statement. Circle True or False.
1. Skip counting by 5s: the next after 45 is 50.
True False
True — adding 5 to 45 gives 50, and 50 is the very next number when you count by 5s.
2. Skip counting by 2s: 10, 12, 15 is correct.
True False
False — 15 is an odd number, but counting by 2s should stay on even numbers like 12, 14, 16.
3. Skip counting by 10s: 100, 110, 120 is correct.
True False
True — each number adds 10 more, so 100, 110, 120 is a perfect count by tens.
