Take your class on a deep-sea adventure with One More, One Less - Let's Sail! In this exciting underwater quest, students answer questions correctly to collect treasure from the ocean floor. Each piece of treasure carries a different point value, adding an extra layer of excitement as they compete to collect the most points.

As they dive into learning, students will be challenged to identify the number that comes before or after a given number, with values up to 101. This foundational skill supports number fluency, sequencing, and place value understanding - all through a game that keeps learners hooked from start to finish.

One More, One Less - Let's Sail is the perfect game for numeracy warm-ups, early finishers, small group interventions, or centre rotations. Students will love the ocean theme and competitive element, while teachers will appreciate the curriculum-aligned focus on number patterns and mental maths.
