Description

You’ve reached the tomb, and it’s time to get the treasure! In this interactive digital game, students must think carefully and act strategically. After each correct answer, they unlock a piece of treasure, but they’ll need to decide whether to play it safe and collect it, or risk it all and go for a bigger score!


This version of the game focuses on comparing mass. For each question, students are shown two objects and must decide which one is heavier or lighter. This builds understanding of comparative language and measurement concepts through visual reasoning and real-world context.


Let’s Steal – Mass: Heavier or Lighter? encourages critical thinking, risk management, and teamwork when played with others. It’s a great way to reinforce measurement vocabulary in a fun, high-stakes format students love!
