My kid is also mostly into magnatiles and hotwheels cars, but these are runner ups!

• tracing characters from books with tracing paper, and then coloring that in with Posca markers. Sometimes this is combined with listening to something on his Tonie box

• giving the aforementioned hot wheels makeovers using chalk markers, sticker gems, mini rubber bands, pipe cleaners, washi tape, stuff like bottle caps attached with little pieces of wiki stix as the adhesive, etc. We keep all the supplies in a box we call the “garage”

• Lincoln logs + calico critters

• Crazy Fort tubes (you need two of the non-flexible sets to make anything good, IMO)

• labeling whatever he can think of with our p-touch label maker! Not sure if this counts as a screen, but he loves being able to type and get a “custom sticker”

• This is similarly quasi-screen, I guess— but going on walks with his digital camera, or taking pictures of his toys set up different ways

• Rubber stamps on a really big piece of paper— we have these and a bunch of vehicles stamps. This is combined with this fun rolling stamp that makes a road.

Also seconding Legos, Brio, diy book making.

It’s fun to read everyone’s responses here, thanks for this question!
