Here is a great craft you can do indoors or outdoors: Kartoffeldrucken (potato prints)!
Parent supervision / help will be needed with the knife and cutting part, but the rest children can likely do themselves.
You can download and watch Lisa3’s lesson about Kartoffeldrucken in German.
Tip 1: If you plan to do letters, make sure to cut out the mirror image so when you print it, it will be the right way around.
Tip 2: If you are ready to make a new print shape, just slice off your old shape and start again on the same potato.
Tip 3: After a good wash, your potato scraps are ready to make delicious German Kartoffelpuffer (potato pancakes)!
