Much to our surprise, after reading the story of Jack and the Beanstalk, our magic beans actually worked!!!! After we had left them on the floor they must have sprouted - even without the things that we learned most plants need to grow! (That's water, sunlight and, in most cases, soil!) Our beanstalk reached right to the ceiling and at the top - a castle! 
Monday morning a GIANT letter for us - we had a challenge from the giant himself. Here we are measuring, finding things that were longer and shorted than his footprint.
