... Interpret the product (a/b) × q as a parts of a partition of q into b equal parts; equivalently, as the result of a sequence of operations a × q ÷ b. For example, use a visual fraction model to show (2/3) × 4 = 8/3, and create a story context for this equation. Do the same with (2/3) × (4/5) = 8/15. ...

SCIENTIFIC NOTATION
... Calculating with Scientific Notation Not only does scientific notation give us a way of writing very large and very small numbers, it allows us to easily do calculations as well. Calculators are very helpful tools, but unless you can do these calculations without them, you can never check to see if ...

If the first digit you remove is 4 or less, drop it and all following digits. 2.4271 becomes 2.4 when rounded off to two significant figures because the first dropped digit (a 2) is 4 or less. • RULE 2. If the first digit removed is 5 or greater, round up by adding 1 to the last digit kept ...
