Dive deep and start your treasure hunt! In this ocean-themed digital game, students answer time-based questions to collect treasure from the sea floor. Each correct answer helps them unlock a new piece of treasure; some small, some large, each with a different point value!

In this version of the game, students practise converting percentages to their decimal equivalents. Each multiple-choice question displays a percentage, and students must select the correct decimal match. The activity includes a range of question types, including extension challenges featuring percentages greater than 100%, encouraging deeper understanding and application of place value knowledge.

Let’s Sail: Percentages to Decimals provides targeted practice for a key concept in upper primary and beyond. The underwater adventure theme adds excitement, while the point-based rewards motivate students to stay focused and strive for accuracy as they master this vital maths skill.
