A suggestion for children, which can be implemented very easily.
Find the materials together.
The children can make all the variations they think of.
You can use the materials you want to use.
As an idea, you can create lay combinations in advance (see example photos) and photograph them, then print them and laminate them, or develop them as photos.
This creates images that the children can reproduce.
Here are a few examples of picture cards that you could use printed as a default!
Templates of outlines can also be used as lay possibilities or as a follow-up. Print, laminate and play.
With this variant, kindergarten children can play with it.
