## Maths Connections

### Factors

Students explore the connection between multiplication and division, and between factors and multiples. They use data about the characteristics of numbers to develop number sense and explore multiple representations.

Eric Weisstein's MathWorld bills itself as "the web's most extensive math resource." MathWorld's pages on square numbers, triangular numbers, and prime numbers contain lots of interesting information and links, and include content that will appeal to everyone from middle-school students to college professors.

The MacTutor History of Mathematics, hosted by the University of St. Andrews, Scotland, has a detailed history of prime numbers.

The Prime Pages includes lists of prime numbers, brief histories of prime numbers, and an ongoing record of the largest known prime number.

### Number Properties

Students recognise and generalise patterns in types of counting numbers. Specifically, students will create different arrangements of the numbers from 1 to 100; colour all of the square numbers, triangular numbers, or prime numbers; and then describe, explain, and extend the patterns they see.

### Guess My Decimal

Students play games in which they are asked to guess a mystery decimal. They complete six games, each of which has a mystery number between two values, attempting to guess the number in as few guesses as possible.
