Mario's Early Years: Fun With Numbers is a Super Nintendo educational game intended for younger audiences and part of The Software Toolworks's series of educational games featuring Nintendo's Mario, named the Mario Discovery Series. It was the first of three "Mario's Early Years" games, released across September, October and November of 1994.
Mario, Princess Peach and Yoshi explore a series of islands that teach them about numbers, shapes and differences. The player uses the SNES Mouse to select their answer from the screen. Luigi works as the assistant for each of the mini-games, and other Mario characters (like Toad and Bowser) make cameos to encourage the player.
