  1. I’ve been planning to use toothpicks and marshmallows to build SOMETHING- and now we have a book to use an amplifying activity…I am in LOVE with the bridge book and concept. We will be doing that activity in the future for sure….

  2. I love building activities sparked by books. Building is my favorite kind of creativity, I think because it all goes back to my days of Lego building as a kid! The variation in this post is awesome!

  3. What an amazing camp! I would have loved to have been in your class.

    Thank you for linking to Read.Explore.Learn. I am pinning this post.

  4. I love all of these! So creative and so clever. How fun.

  5. Can I just say awesome?! You did most of the work for us. I love connecting books with projects. My son’s two favorite things. My son’s a little old for some of these things, but we can certainly work on them together or have friends over to create together. I would LOVE to see more of the same. Thanks!

  6. This is incredible! Am pinning and reposting now!

  7. Found you from “I Can Teach My Child”. I love these ideas and the creativity it sparked. I’m going to pin this to use next summer, when I try to do activities and fun stuff with my own children. Thanks so much!

  8. Great ideas. I love when the children create their own challenges. We will have to try your bridge penny challenge.

  9. I love everything about this post! We have some tin can robots just like that too – we used magnetic letters to give them names too!

  10. These are amazing! How you need for each lesson? Do you think an hour is long enough for the read aloud and activity?
