Curriculum: Investigate and use the properties of odd and even numbers (ACMNA071)
Elaboration:
Elaboration:
- using the four operations with pairs of odd or even numbers or one odd and one even number, then using the relationships established to check the accuracy of calculations
Number Maze
Tuning In:
1) What makes a number odd or even?
2) Do you know of ways that people use odd and even numbers to check their answers? e.g. smart lazy?

Problem Solving: Number Maze
Students are presented with a number maze. As they move through the maze, students need to total the numbers on the path they follow. The challenge is to complete the maze with an odd total. By exploring possible solutions to the maze, students form generalisations about the results of adding odd and even numbers. They see that an odd number of odds in the sum is required to get an odd total.

Lesson 2: 10 to 1
This task challenges students to use addition, subtraction and the numbers 10 down to 1 to make a total of 27 and a total of 12. They will see that it is possible to create only an odd total with these numbers. Students look at the largest and smallest positive totals for the problem. They also look at the ways in which they can modify the task to create even totals.
