Thousandths 2
This 11-question quiz keeps decimal addition at the thousandths place while pushing the numbers into the hundreds.
You will work through sums like 128.684 + 10.254 = ? and 504.871 + 24.215 = ?, along with a few true or false items.
The longer the number, the more it helps to keep every place value lined up, so writing the digits in neat columns saves a lot of mistakes.
One of the false statements has too many digits after the point, a classic trap when you are adding thousandths.
Recommended level: intermediate.
