How do I build the Mission Models?

1. Sort the LEGO element bags (found in your Challenge Set box) by bag number. They are labeled 1-10.
2. Match the bag numbers with the corresponding bag numbers below.
3. Open the correct pdf files and have an awesome time assembling the models. We strongly recommend opening one set of bags at a time so elements are not mixed up.
4. Once all models are assembled, go to the Challenge page to assemble the field and find out what the missions are.
   Have fun!
