We're a day late due to the holiday but we did do an unplugged project.
I printed out some pictures of animals using Microsoft word clip art - two sets, one for each child. Some were insects, some were not. Some were tricky (spiders), some were not (elephants). We got two pieces of paper for each child, labeled "Insects" and "Not insects" and the kids cut and pasted the animals into the right category.
They liked it a lot and are proud of their "posters" on our wall. It was super simple for me and was a great learning opportunity for both.
