Sep 24, 2022
link

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. 

parallel

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: 

parallel

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.
