Whole numbers to one billion

Practice 3 items →

Same place-value machine, three more zeros. Multiplying by a power of ten is a shift, not a superstition about adding zeros. Students read and round through one billion and multiply and divide by 10, 100, 1,000, and 10^k.

Ready when

$3.07 \times 10^3$ and $4{,}800 \div 10^2$ are both automatic.

Watch for

$4.2 \times 100 = 4.200$ ; $56{,}000 \div 100 = 56{,}0$ .
