Hi This is my place velu maths and I used a object.

Rename numbers using the Learning Object

Use the Learning Object

Example:  Put 15 tens in the tens column.  What is the total? 150.

1. Put 12 tens in the tens column. What is the total? 120
2. Put 9 tens in the tens column.  What is the total? 90
3. Put 20 tens in the tens column.  What is the total? 200

Try without the Learning Object

4. What is the total of 16 tens?160
5. What is the total of 22 tens? 220

Make these numbers with the Learning Object. Finish writing on the lines.

6. 140 =  1  hundreds  + 4  tens  +   0 ones
7. 140 =  1  hundreds  + 4  tens  +   0 ones
8. 243 =  2  hundreds  +  4 tens  +   3 ones
9. 243 =  2  hundreds  +  4 tens  +   3 ones
10. 602 =  6  hundreds  +  0 tens  +   2 ones

Try these with the Learning Object. What is the total number?

11. 0 hundreds + 5 tens + 12 ones = 62
12. 3 hundreds + 12 tens + 9 ones = 429
13. 2 hundreds + 7 tens + 14 ones = 284               
14. 3 hundreds + 13 tens + 12 ones = 342

How many tens?

What is the total number of tens in these numbers?  Use the Learning Object to help you.

1. 245 = 4  tens
2. 421 =2 tens
3. 653 =  5 tens
4. 325 =  2 tens
5. 252 = 5 tens

What is the total number of tens in these numbers?  Try without the Learning Object.

1. 563 =  6 tens
2. 371 =   7 tens
3. 264 = 6  tens
4. 535 =  3 tens
5. 646 =  4 tens

What is the total number? Try without the Learning Object.

1. 17 tens = 170
2. 23 tens = 230
3. 47 tens =   470         
4. 35 tens = 350
5. 24 tens =240
