Solve, climb and win! Players will enjoy solving Betty the Yeti's addition and subtraction problems in order to race their way up the mountain as they play Summit Sums Addition & Subtraction Game. As they make their way up this educational game’s mountain, children will draw Betty the Yeti’s equation cards and need to answer the addition or subtraction problem correctly to advance that number of spaces. Watch out though, as the mountain comes with its fair share of hazards, from gigantic boulders to that meddlesome Frankie the Goat, who’d love nothing more than to block the path of an advancing maths mountaineer! Suitable for 2 to 4 players.
