**Voyager Game:**

**Data Canister:** If the
numbers are
getting bigger, they are either adding or multiplying by the same
number.
Compare the first two numbers... in this case, to go from 3 to 11, they
are probably adding 8. Check by adding 8 to 11... you get the next
number:
19. If adding doesn't work, try multiplying. When you've found the
pattern,
use it to get the missing number.

As students continue, the
Data Cannister
problems start to include patterns with fractions. In this example, the
denominators are all the same, (8), while the numerators are increasing
in a recognizable pattern, so the missing number is 6/8. As these get
harder,
students may need to convert some of the fractions to get a common
denominator.

**Ballast Control Panel: **click
on
numbers until they add up to the amount of ballast you need. For
instance,
to get 59 pounds, you could click on 25, then another 25, then 5, then
on four 1s. Click Done when you're finished.

**Toxicity Graph:** To
find how much
the toxicity has decreased or increased over two days, find the amounts
for each day and subtract. Note that in this example, the amount for
Yesterday
was 1800-- in between the 1600 and 2000 lines.
