Introduction
I have designed this webquest to help students learn the maths of how to investigate the properties of odd and even numbers in year 4.
Do you struggle knowing the difference between which numbers are odd and which are even? Then this is the webquest for you. We will be learning how to investigate the properties of odd and even numbers, how to formulate rules to identify whether a number is odd or even, recognising patterns and relationships between numbers and calculations, and how to use different operations on combinations of numbers and whether these will result in calculating odd or even answers. When you are ready to find out your task click on the "task" button. I wish you speedy learning.
Task
Investigating the properties of odd and even numbers in year 4 :
This webquest will lead to three different lessons on odd and even numbers.
We will learn about:
1- how to formulate rules on identifying whether a number is odd or even.
2- recognising patterns and the relationships between odd and even numbers.
3- Using different operations on combinations of numbers and whether these will result in calculating odd or even answers.
I hope that this webquest helps answer any uncertainties students may have, and that it will help students to know and learn the difference between odd and even numbers. Click on the "process" button to continue to the three pre-planned lessons.

In this movie, you’ll learn about even and odd numbers.
Even Numbers
Any integer that can be divided exactly by 2.
The last digit is 0, 2, 4, 6 or 8
Example: −24, 0, 6 and 38 are all even numbers
Odd Numbers
Any integer that cannot be divided exactly by 2 is an odd number.
The last digit is 1, 3, 5, 7 or 9
Example: −3, 1, 7 and 35 are all odd numbers
Adding and Subtracting:
When we add (or subtract) odd or even numbers the results are always:
| Operation | Result | Example (red is odd, blue is even) |
|---|---|---|
| Even + Even | Even | 2 + 4 = 6 |
| Even + Odd | Odd | 6 + 3 = 9 |
| Odd + Even | Odd | 5 + 12 = 17 |
| Odd + Odd | Even | 3 + 5 = 8 |
(The same thing happens when we subtract instead of adding.)
