2 × 10 =
0:00 of 3:04
Times 10 moves each digit one place left.
A zero fills the ones place.
5 × 10 = 50: 5 jumps of 10 from 0 land on 50: 10, 20, 30, 40, 50. Jumps of 90 work the same way: 2 jumps of 90 land on 180.
Each jump of 10 is 1 ten, so 5 jumps of 10 is 5 tens: 50.
3 × 10 = 30: 3 jumps of 10. And 2 × 90 = 180: 2 jumps of 90.
Bigger jumps work the same way: count the jumps, read the landing. 90 is 9 tens, so a jump of 90 is 9 tens at once.
The number of jumps times the size of a jump is where you land.
Adding instead of jumping: 5 and 10 make 15.
5 jumps of 10: 10, 20, 30, 40, 50. So 5 × 10 = 50.
7 × 10 = ___ — 70. 7 jumps of 10: 10, 20, 30, 40, 50, 60, 70. So 7 × 10 = 70.
Let's find 3 groups of 10. How many is that in all?
Here are 3 groups of ten, all lined up.
Let's count by tens: ten, twenty, thirty.
There's a fast way too. Start with the number three.
Now put a zero right after it — every digit shifts one place to the left, and a zero fills the ones place.
So three times ten equals thirty.
Three times ten is thirty! This trick works for any number times ten.
