In this unit you are going to need your ruler to measure the
length of fish. The measurements and other information about
the fish will be our data to tell a story about a fish farmer.

Collect and organise data

Jabu farms with goldfish. He sells the fish to people who keep
them as pets. He has three kinds of goldfish: Huna (blue-grey),
Hibuna (gold) and Syubunkin (spotty).

Goldfish live up to 20 years and they require good care.
Fish of different sizes have different prices. We are going to
imagine we use data to help Jabu find the sizes of his goldfish.

Huna goldfish Hibuna goldfish Syubunkin goldfish

Jabu has 20 goldfish in Tank A. Imagine that they are the goldfish
that you see on pages 88 and 89. You have to measure these
goldfish and make a list of their measurements.

Plan ahead
Make a plan so that you will know
which measurements are of Huna
fish and which are of Hibuna fish.
Plan how to measure accurately.
Measure from the nose to the end
of the body. Fish don’t keep their
tails still, so you can’t measure
their tails accurately!
