Understand Place Value Relationships - 4th Grade Math

$2000$. The $2$ is in the thousands place: $2 \times 1000 = 2000$.

$200$. The $2$ is in the hundreds place: $2 \times 100 = 200$.

$20$. The $2$ is in the tens place: $2 \times 10 = 20$.

$2$. The $2$ is in the ones place: $2 \times 1 = 2$.

$10$. To get from $900$ to $9{,}000$, multiply by $10$.

$10$. To get from $56$ to $560$, multiply by $10$.

$10$. The $6$ moves one place right, so divide by $10$.

$10{,}000$. The $1$ is in the ten thousands place: $1 \times 10{,}000$.

$500$ is $10$ times $50$. Check: $50 \times 10 = 500$ (true), but $5 \times 10 = 50$ (false).

$300$. Moving one place left multiplies by $10$: $30 \times 10 = 300$.

$80$. Moving one place right divides by $10$: $800 \div 10 = 80$.

The $9$ in $900$. The $9$ in $900$ is one place left of the $9$ in $90$.

Thousands place. The $5$ represents $5$ thousands in this number.

Its value becomes $10$ times as great. Each place to the left is worth $10$ times more than the place to its right.

$70$. The $7$ is in the tens place, so it represents $7 \times 10$.

$700$. The $7$ is in the hundreds place, so it represents $7 \times 100$.

$10$. Moving one place right divides by $10$: $700 \div 70 = 10$.

Thousands place. The $6$ is in the fourth position from right, which is thousands.

The $4$ in $40$. The $4$ in $40$ is in the tens place, which is $10$ times the ones place.
