Otter Ocean
Learn Odd & Even Numbers in an Underwater Adventure
Dive into the deep blue with Otter Ocean, the refreshing way to learn about Odd and Even numbers. Designed primarily for Year 2 students, this game combines swimming mechanics with number sorting to reinforce a key property of numbers.
Help Oliver the Otter collect the correct pearls while avoiding the jellyfish! It's an underwater test of number sense and reflexes.
🦦 How to Play
- Check the Rule: At the start of the round, you'll be told to collect either ODD numbers (1, 3, 5...) or EVEN numbers (2, 4, 6...).
- Swim!: Use your mouse or finger to guide the otter through the ocean.
- Collect Pearls: Swim into the clams holding numbers that match your rule. Collecting a correct number earns points and a happy crunch sound!
- Avoid Hazards: Don't touch numbers that break the rule, and watch out for stinging jellyfish!
📚 Curriculum Focus (Year 2)
Otter Ocean supports the Year 2 National Curriculum objective for Number and Place Value:
- Odd and Even Recognise the parity of numbers (odd or even).
- Pattern Recognition Understand that even numbers end in 0, 2, 4, 6, or 8, and odd numbers end in 1, 3, 5, 7, or 9.
- Recall Rapidly categorize numbers as they appear on screen.
🧠 Why Learn Odd & Even?
Understanding parity (odd/even) is essential for mental division and recognizing patterns.
- It helps with division: Only even numbers can be halved into whole numbers.
- It's a checking strategy: "I added two odd numbers, so the answer must be even. My answer is odd, so I must have made a mistake."
👨👩👧 Tips for Parents
The "Pairing" Test:
"Get a pile of socks (or coins). Count out 5. Can you put them all in pairs?"
Child: "No, there is one left over!"
Parent: "That means 5 is an ODD number. Odd numbers always have an 'odd one out'!"
Designed for UK Year 2. Compatible with White Rose Maths "Properties of Number".
