... These are open-ended tasks with many correct answers. Encourage students to describe the range of answers in general terms. For example, in the first case, if the digit in the ones place (in the number on the left) is 0, 1 or 2, then the digits in the next two places (tenths and hundredths) can be a ...

significant digits
... 2. All zeros which are between non-zero digits are always significant. Ex. 901 (3), 321.09 (5), 1011(4) 3. Zeroes to the left are NOT significant, and serve only to locate the decimal point. Ex. 0.0987(3), 0.00001(1) 4. Zeros to the right MAY be significant, if it is also to the right of the decimal ...
