This is a simple, yet very engaging activity that you can use to enhance your students' learning of ratios and ratios in simplest form. It uses the typical pattern blocks that you see in most classrooms, yellow hexagon, red trapezoid, etc...and it allows students to get in groups and create whatever they'd like. I've had students create Minion replicas, flower gardens, houses, words, and even cars out of these pattern blocks and they are amazing!

You can even make it more difficult by creating your own ratios and having students use those ratios to create something amazing!
