When I was in Kindergarten I did a camping theme that included:
A bulletin board with 3D S'mores that read "S'more Books You'll Love!" (I used a wooden skewer but a thin twig would be better, sheets of craft foam for cracker and chocolate, and a "fake" marshmallow that was part of a foam snowman craft from Oriental Trading...too cute!)
I crumbled a long sheet of brown kraft paper to resemble rocks and made a cave in the corner so the children could read inside it. I had low bulletin boards and so I could staple it on for support but you could use a small table or desk as the base on which to place the paper.
I had a backpack with a compass, map, binoculars, butterfly net, pencil, etc. so the children could hike around the room and collect bugs, rocks, and butterflies that I "hid" in plain site. Each had sight words, letters, values, numbers, etc. depending on what was being practiced that week.
I had a set of steps that flipped to be a rocking boat which I placed on paper water. The hikers could pretend it was a raft and float downstream back to their base camp where activities could be completed.
At Halloween we did lots about bats and the cave had a spelunkking physical activity drawn on picture cards.
Some title you might be able to use:
Take a Hike
H.I.K.E. notebooks that stand for "Helping Independent Kids Explore"
Climb to the Top
Going in the Right Direction (Use GSP or compass)
Trail Guides for your job board if you have one ...or Seasonal Naturalists
Scale to the Top
