Odd or even numbers

Here you get to practice recognizing even and odd numbers.

Instructions for Odd or even numbers

All numbers are either even or odd. If a number is a multiple of two (2), it is an even number; otherwise it is an odd number.

You will see a number between one and twenty (1-20) on the screen. Your task is to choose whether it is an even or odd number by clicking the correct answer below the image. On the second level, choose the number that is either odd or even.

Calculation of knowledge points

Each completed game level gives 1 knowledge point in Odd or even numbers. The maximum number of points (6 knowledge points) is achieved when you pass all 6 levels. You'll get a bronze medal when you complete a level 2 times and a silver medal after 5 completed rounds. A gold medal will be received after 10 completed rounds. In Odd or even numbers, the maximum number of collectable gold medals is 6. You only earn knowledge points for levels that has not been cleared before. A cleared level has a green background above. Even when you have completed a level, you can continue practicing at that level, but it gives you no more knowledge points.
