Learn Counting Sequence and Patterns from 10s to 120
Count:
To say numbers one after the other in order, or to calculate the number of people or things in a group.
Count by 10s to 120:
We can use ten frames to count 10s to 120:
12 tens are 120.
One hundred twenty.
Use ten–frames to count by 10s
Example1:
How can you count to 60 by tens?
Sol:
I can use ten frames to count by 10s.
Example2:
How can you count to 90 by tens?
Sol:
Use a pattern to count by 10s:
Pattern:
A repeating arrangement of numbers, colors, and shapes.
The above numbers follow ‘0 ‘in one’s place.
- Write the missing numbers:
Sam wrote a pattern. He forgot to write some numbers.
What numbers did Sam forget to write?
50, 60, 70, ______, 90, ______, 110, 120.
Sol:
50, 60, 70, ______, 90, ______, 110, 120.
Skip count by 10s
70 after 80
90 after 100
Sam forgets 80 and 100
50, 60, 70, 80, 90, 100, 110, 120.
