If you purchased the Castle Project from Algebrains, you will definitely want to consider getting this extension activity: Beauty versus Destruction! This takes the fun of building a castle to a whole new level. Students will compete in one of 2 categories. The Beauty Category has students vote on the best looking castles. The Destruction Category determines whose castle can withstand barbarian attacks the longest (generated using probability concepts and dice). Students love it and will remember it for the rest of their lives! It can get messy and will require you to get a few items like golf balls, a bat, etc., but if you want your students to have a ton of fun while learning about geometry and probability this product is for you. Product comes with instructions for students, instructions for teachers, a list of supplies needed, a chart with random barbarian attacks for dice rolls, and 6 colorful certificates for the top 3 winners in each category.
