Blast off into outer space! In this interactive digital game, students will warp between galaxies and collect fascinating objects as they work through a series of measurement questions. Each correct answer helps them earn space badges and unlock new cosmic worlds to explore.

In this version of the game, students will decide which informal unit of measure is best suited to measure a given object’s length. Options may include paperclips, counters, pop sticks, or blocks, supporting practical understanding of length in everyday contexts. Each question strengthens comparison skills and reinforces when and why to use different informal tools.

Let’s Explore – Choosing Informal Units of Measure: Length blends curriculum-aligned maths content with space adventure. The more correct answers students give, the more objects they collect and at the end of the game, they’ll see just how many badges they earned among the stars.

Key Learning Outcomes:

• ✅ Identify appropriate informal units to measure length
• ✅ Compare and describe lengths using everyday items
• ✅ Develop foundational measurement vocabulary and reasoning
• ✅ Strengthen estimation and tool selection skills
• ✅ Engage in meaningful maths learning through interactive gameplay

How to Play:

1. Students are shown an object and asked to choose the best informal unit to measure its length.
2. A correct answer unlocks a new space object and warps them to the next galaxy.
3. Each object collected contributes to their space badge tally.
4. The game continues through a series of questions.
5. At the end, students are shown how many space badges they’ve earned across the journey.

Ideas for Classroom Use:

• 💡 Use during your measurement unit to introduce or consolidate informal measuring tools.
• 💡 Great for Year 1–2 students learning to compare and estimate lengths.
• 💡 Pair with hands-on classroom tasks using actual informal units (e.g. measure your pencil with paperclips).
• 💡 Replay to build familiarity and fluency with different informal tools.

Top Teacher Tips:

• 💛 Send the QR code home for students to play as a homework or revision task.
• 💛 Let students personalise their experience by choosing from six 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.
