Study the above pictures. Do we first compare how many TENS the numbers have or how many ONES the numbers have?
For example,
92 has more TENS than 89. Therefore 92 is greater than 89.
The symbol > means "greater than", and
< means "less than".
The open end or open mouth of the symbol ALWAYS points to the bigger
number.
For example,
|
3 < 5 |
14 > 3 |
60 > 50 |
48 < 99 |
7 < 17 |
You can also use the number line for help.
Since 44 comes before 47 when you read the number line from left to right, 44 < 47.
1. For each number, draw sticks to represent the tens and dots to represent the ones. Then write either < or > in between the two numbers.

|
2. Find the numbers on the number line and write either < or >.

5 + 20 |
30 + 5 | 70 + 2 | 70 + 7 | 80 + 5 | 8 + 50 |
6. What are these numbers? All numbers are less than 100.
| a) "I am more than 55 and less than 65. I
have the same amount of ones as 27." |
| e) "I don't have any whole tens. If
you add five to me, you get a dozen." |

P.S. ....
| Check out these short video clips from my favorite band - Rockabilly.US. They play oldies, Elvis, country, and top hits of the 50s and 60s. It's a show with large band, costumes, choreography, little skits, "Kid Kritters", 6 dancing/singing girls, junior dancer troupe, etc. | |
|
"Be My Baby" originally by the Ronettes |
Impossible Dream (Elvis song) |
| Most importantly, the band wants to use the uplifting and energetic music to bring some fun, happiness and encouragement into people's lives. They're doing it selflessly to help others, and don't get paid for any of it themselves. And I admire that! | |
