**TrellisMATHS Properties of Number** includes six
programs which focus on sequences of positive integers including
even, odd, triangle, prime, square and cube numbers, multiples,
factors and powers.

**Numbers, Multiples and Factors** are resource
programs which allow students to explore sequences of integers,
involving number properties, displayed on grids of varying size. Up
to three sequences at a time can be displayed on the grid. Numbers
common to all sequences are highlighted on the grid.

**Numbers** includes a range of sequences. **
Multiples** is a variation of **Numbers** with a
focus on multiples. **Factors** is a variation of
**Numbers** with a focus on factors. **Define**
challenges students to define a number uniquely by selecting from a
list of statements involving number properties.

**Identify** challenges students to identify a
number, chosen at random by the computer, by selecting from a list
of questions involving number properties.

**Factor Challenge** is a strategy game played
against the computer which develops students’ understanding of
factors and prime numbers. In all six programs, students are able to
choose the number of rows and columns in the grid and, in all
programs except Factor Challenge, the starting number.

Within each program there is a ‘Make Notes’ facility which
allows students to copy a screen display and paste into a
word-processing package (using the buttons on the tool bar). This
allows students to keep a record of their work and allows them to
further analyse their results away from the computer. It can also be
used to generate blank number grids of varying size.
