About this adventure
Odd and Even Numbers is an interactive maths game that teaches children aged 6–8 how to tell odd and even numbers apart, matching Year 2 maths in the national curriculum for England. Children help Pip the puffin seat friends in two-seat boats: when everyone has a partner the number is even, and when one is left over it is odd.
Next, players build the 2 times table by counting puffin feet in twos along a number line, then use division by 2 to work out how many pairs there are. They discover a shortcut for numbers up to 100: only the ones digit decides, because every ten is five pairs.
The final island explores number patterns, from house numbers on a street to the odd, even rhythm of the 5 times table. Spoken narration, gentle hints and typed answers support every step, and a ten-question challenge rounds it off.
Questions and answers
How do you know if a number is odd or even?
To tell if a number is odd or even, look at its ones digit. If the ones digit is 0, 2, 4, 6 or 8 the number is even, and if it is 1, 3, 5, 7 or 9 the number is odd.
What is an even number, in simple words?
An even number is one you can share into pairs with none left over, such as 6 or 12. An odd number always has one left over when you make pairs, such as 7 or 15.
Is zero an odd or even number?
Zero is an even number. With zero objects there is nothing left over when you make pairs, and numbers ending in 0, such as 10, 20 and 30, are always even.
What age is this odd and even numbers game for?
The game is designed for children aged 6 to 8 and matches Year 2 (KS1) maths in England. Confident younger counters and older children who want a refresher can also play it comfortably.
What does the odd and even game include and how long does it take?
It includes four chapters, an optional counting-in-2s warm-up and a ten-question final challenge, and takes about 35 minutes to play through. Children can start with any chapter and go back to the map whenever they like.
