At this daycare, kids mostly do a lot of free play. It's not structured at all, which is great. But usually they do some small art or crafts project and go for a walk in the nearby park. The teacher tries to introduce numbers, letters, shapes, etc. through each game and I think it works. Mark has learned a lot of words there.
The rest of the time it's just me and Mark. Again, usually our days are pretty unstructured. We drive Chris to work and stop by to watch the daily Amtrak train on the way back. We go to the Marbles museum, to different parks and playgrounds, feed ducks, pick strawberries, play in the yard, watch cartoons, read, ride a toy train and a carousel at Pullen Park, and cook and do other stuff around the house.
So I've made lots and lots of different little games centered around the dinosaur theme. And I got some colorful dino books at the library. Unfortunately, Mark decided to renew his interest in trains that same week. Instead of being into dinosaurs (per my plan), he was and still is into drumming and trains (per his plan).
We still managed to learn a few new things:
1. New color - purple (and no, we didn't watch Barney at all). So now Mark knows all his basic colors - black, white, red, green, yellow, blue, orange, purple and can name all of them.
3. New letter - Д for dinosaur
4. A couple more words - volcano, lava
5. Food sorting into "fruits and veggies" and "meats" (when we fed dinosaurs)
6. Dividing and sharing - when Mark was dividing a hot dog and orange into pieces to feed each one of the 4 toy dinosaurs
Sure, that's not much for 2 weeks of dinosaur stuff (ok, my one week stretched into two). But again, we spent maybe 5-10 minutes a day talking about dinosaurs and playing dino-themed games. And some days we didn't bother with dinos at all.
