Visit the robot factory where you will mix and match various body parts to build a robot.

Use this game to reinforce the skill of adding one when mentally adding simple sums to 10. Students will practise recognising number patterns and build fluency with one more than a given number. Each correct answer unlocks a new robot part, encouraging repeated practise while giving students the joy of creating their very own robot character.

Who will build the ultimate robot while mastering the skill of adding one?

Key Learning Outcomes:

• ✅ Mentally add one to numbers within 10
• ✅ Strengthen automatic recall of number facts
• ✅ Recognise number patterns and build number sense
• ✅ Develop fluency through repeated, meaningful practise
• ✅ Engage in independent or collaborative learning through interactive play

How to Play:

1. Students are presented with a simple equation requiring them to add one to a number between 1 and 10.
2. They must select the correct answer.
3. Each correct answer unlocks a new robot part to add to their custom-built creation.
4. Once they have completed their robot, students can watch their finished creation celebrate their success!
5. Replay the game to build different robots and reinforce learning.

Ideas for Classroom Use:

• 💡 Use during maths warm-ups, rotations or number fact fluency lessons
• 💡 Great for Foundation to Year 1 students developing early addition strategies
• 💡 Pair with number lines or manipulatives to support concept development
• 💡 Replay regularly to build confidence and consolidate skills with adding one

Top Teacher Tips:

• 💛 Let students personalise their experience by choosing from six robot characters before the game begins
• 💛 Select the number of players or teams at the start of the game to suit individual, paired, or group play
• 💛 Send the QR code home for students to play as a fun revision or practise activity
