Summer Curriculum

I know the kids are still young, but I am really trying to take advantage of the weather and get in as many outdoor types of activities as possible...while we have more sun than rain.

So, far, we have spent our summer involved in the following activities:
building sand castles
practicing pouring and digging on the beach
collecting shells and rocks
city walks (often helped by a stroller ride)
exploring all areas of the zoo
tending to Georgia's veggie garden (tomatoes, radishes, and strawberries)
feeding our compost worms
practicing balance and gravity at the park
writing with sidewalk chalk
more pouring with water in our backyard pool
learning to balance and ride G's Skuut bike (balance bike)
Berry picking

We plan to also include:
horseback riding on our horse, Star
camping with our friends, Leah and Thom
visiting a water park
swimming in an outdoor pool

Any other suggestions?
