This is an activity we’ve done on an airplane that works really well.
Prep: I printed out pictures of a road, the water and the sky. You could definitely just draw these as part of the activity on the plane. I then cut out stickers of things that were found in each location. I placed the stickers in a zip-up pencil bag. J pulled out one sticker at a time and decided which setting it should be placed in. This worked really well and kept him occupied for awhile (he had a lot of stickers to place).
We’ve also done a similar activity in a hotel room. I drew a train track, road and lake on some paper and he found stickers to place on each. He was then quite content to drive his cars around the tiny road for quite awhile!
Finally we’ve done something similar at a restaurant. I have a random assortment of items in my purse at any given moment. In this case stickers and index cards. We drew a setting on each one and he sorted the stickers.
These type of activities would also work well for long doctor appointments and car rides.
We do lots of sticker sorting around here since it is a great way for J to practice categories and also helps him with fine motor skills (getting the stickers off really works those pincher muscles). It also requires little prep on my part and the only supplies necessary are paper and stickers!
Here are a couple other examples I’ve posted on in the past:
We’ve also done shapes, seasons, letters and animal homes. The possibilities are limited only by your sticker collection.
