Students correctly answer questions to reach the top of the mountain. How far will they make it up the mountain? As they progress higher up the mountain, the scenery will change from grassy trails to snowy peaks. At the end, a polaroid snapshot shows how far they climbed and their final score. This is a cooperative game where, if there is more than one player, they must work together to reach the summit as a team.

In this version, students practise identifying numbers that are 10 more or 10 less than a given number, within the range of 1 to 100. This foundational place value skill helps develop number sense and mental computation fluency. Support students may use a hundreds chart to assist with visualising the patterns and relationships between numbers.

Let’s Hike – 10 More 10 Less to 100 is ideal for Foundation to Year 2 students learning to navigate the number system. It’s perfect for numeracy warm-ups, place value rotations, or as a fun, goal-oriented activity using the QR code.

Key Learning Outcomes:

• ✅ Identify numbers that are 10 more or 10 less within the range to 100
• ✅ Strengthen understanding of place value and number patterns
• ✅ Develop mental strategies for number manipulation
• ✅ Build confidence with counting in tens using visual supports
• ✅ Engage in cooperative gameplay to promote team problem-solving

How to Play:

1. Students are presented with a number and asked to identify either 10 more or 10 less.
2. Each correct answer helps the team climb further up the mountain trail.
3. The game continues until all questions are answered or the team reaches the summit.
4. At the end, students see how far they made it and receive a polaroid-style score snapshot.

Ideas for Classroom Use:

• 💡 Use during place value units or numeracy blocks to reinforce number patterns
• 💡 Great for Foundation–Year 2 students developing counting strategies with visual supports
• 💡 Pair with a classroom hundreds chart to help visualise adding and subtracting 10
• 💡 Follow up with a written challenge: fill in 10 more/less tables or complete a number maze

Top Teacher Tips:

• 💛 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
• 💛 Send the QR code home for students to play as a homework or revision task

Let’s Hike – 10 More 10 Less to 100 builds number sense, teamwork, and place value understanding all in one exciting mountain adventure!
