This unit is intended
for students in their third year of secondary education. It aims to
reinforce their ability to connect algebraic terms to data, which is
usually given in the form of a table. It also helps them to match
tables of values to given graphs and introduces them to the
basic characteristics of graphs. Furthermore, there are activities
which encourage students to compare two graphs and give a detailed
interpretation of them. In addition, the data used in the examples is
based on situations which are intended to be as realistic as possible.
