# 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.

1. 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.
