First we read the book Iggy Peck, Architect
In the story, Iggy, a budding second grade architect, has to save his teacher and classmates when they become stranded on an island. He builds a beautiful Golden-Gate-Bridge-esque suspension bridge and saves the day.
I asked students to channel their inner Iggy Peck and challenged them to build bridges over "streams" using only 10 legos (if they finished the first challenge, their stream got wider!).
Narrow stream challenge:
Wider stream challenge:
Students were also able to try STEM-themed centers during book checkout. I had additional legos (with challenge cards) and magnatiles (also with challenge cards).
