AC9M4N02

Elaborations

• AC9M4N02_E1identifying even numbers and explaining why all numbers that end in the digits 0, 2, 4, 6 and 8 are even and that numbers ending in 1, 3, 5, 7 and 9 are odd
• AC9M4N02_E2explaining why some materials can be shared evenly between 2 people without leaving a remainder and some cannot
• AC9M4N02_E3explaining the patterns involved in adding, subtracting and multiplying odd and even numbers; for example, even + even = even, odd + even = odd, odd + odd = even and using this to decide whether answers to addition, subtraction and multiplication calculations are correct or not
• AC9M4N02_E4following an algorithm consisting of a flow chart with a series of instructions and decisions to determine whether a number is even or odd; using the algorithm to identify which elements of a set of numbers are divisible by 2
