There are so many options with the Gumball Machine.
OT: Use it like a craft and place stickers, spangles, dots, or write in it. You can use it for alphabet learning if that is what you are working on. You can make a themed gumball machine by cutting out pictures that fit a chosen theme or just practice drawing circles. The options for skill-building are awesome.
PT: You may work on stairs, but have your autistic kids place a fuzz ball in the machine each time they climb the stairs. Kids will easily reach high if they get to place a sticker in it as well.
ST: This can be wonderful for collecting words or placing items of a particular group inside the gumball machine. You can also use it as a sticker chart. If articulation is a goal, you may have them write in the letters that they can say correctly.
