Question

regroup and rename numbers
1 use structure miguel uses base - ten blocks to show that 3,200 people are at a museum. how can you regroup and rename the number 3,200?
2 use the place - value chart to help you regroup and rename the number.
83,000 = 83 hundreds
regroup and rename the number.
3 5,300 = 5300 tens
4 680,000 = 680 thousands
5 71 thousands = 710 hundreds
6 82 ten thousands = 820 thousands
7 some students are playing a math game. each of them must regroup and rename 47,000. circle all of the ways that 47,000 is regrouped and renamed correctly.
47 ten thousands
47 thousands
470 hundreds
47 hundreds
470 tens
4,700 tens
8 math on the spot a toy store is ordering 3,000 remote control cars. the store can order the cars in sets of 10. how many sets of 10 does the store need to order?

Explanation:

Step1: Recall place - value concept

To find the number of a certain place - value unit in a number, divide the number by the value of that unit.

Step2: Solve for 3,200

Since 1 hundred = 100, then $3200\div100 = 32$, so 3,200 = 32 hundreds.

Step3: Solve for 83,000

Since 1 hundred = 100, then $83000\div100=830$, so 83,000 = 830 hundreds.

Step4: Solve for 5,300

Since 1 ten = 10, then $5300\div10 = 530$, so 5,300 = 530 tens.

Step5: Solve for 680,000

Since 1 thousand = 1000, then $680000\div1000 = 680$, so 680,000 = 680 thousands.

Step6: Solve for 71 thousands

71 thousands = 710 hundreds (because 71000÷100 = 710).

Step7: Solve for 82 ten - thousands

82 ten - thousands = 820000, and $820000\div100 = 8200$ hundreds, $820000\div1000=820$ thousands.

Step8: Solve for 47,000

47000÷100 = 470 (so 470 hundreds is correct), 47000÷10 = 4700 (so 4700 tens is correct), 47000÷1000 = 47 (so 47 thousands is correct). 47 ten - thousands = 470000≠47000, 47 hundreds = 4700≠47000.

Step9: Solve for toy - store problem

The store has 3000 remote - control cars and wants to order in sets of 10. Since $3000\div10=300$, the store needs to order 300 sets of 10.

1. 32
2. 830
3. 530
4. 680
5. 710
6. 8200, 820
7. 47 thousands, 470 hundreds, 4700 tens
8. 300
