This Mountain measures 27” in diameter and 12” high and is modestly portable. Its peak elevation is 60. It is excellent for introducing concepts and developing fluency in multiplication. With its expanded number range and number of steps it is better suited to pattern recognition activities than the Mini. The number of players varies by activity up to six. More advanced skills and superior strategies have a bigger payoff when the games are played on the Mega Mountain. Ages 4 to 94.
