You’ve reached the tomb, and it’s time to get the treasure! Do you play it safe and take the small pieces of treasure, or risk it all to get the big score?

Use this game to reinforce the skill of adding six when mentally adding simple sums to 15. Students will practise using +6 strategies to solve problems quickly and accurately, deciding along the way whether to keep their treasure or risk it for more.
